Power Input System

The WX3024 supports several power input modes: AC input only, DC input only, and concurrently use of AC and DC inputs. When AC and DC inputs are used concurrently, they serve as backup for each other.

The WX3010 and WX3008 support AC input only. Only an H3C-recommended redundancy power supply (RPS) unit can be used to provide DC input.

AC power supply

Table 1-5 AC power supply specifications


Rated voltage range 100 to 240 VAC, 50/60 Hz

Maximum voltage range 90 to 264 VAC, 47 to 63 Hz

Maximum system power consumption (without external PoE devices)

100 W 50 W 40 W

Minimum power consumption 220 V × 0.282 A = 63 W

220 V × 0.165 A = 36.5 W

220 V × 0.128 A = 28.2 W

DC power supply

DC voltage range: –52 V to –55 V

PoE Power Supply

The WX3000 series supports Power over Ethernet (PoE) to provide –48 VDC supply to attached powered devices, such as IP phones, WLAN APs, security and Bluetooth APs, through twisted pair cables.

Only the H3C-recommended external PoE power supply can be used as the DC input, rather than the –48 VDC power supply of the equipment room, which may cause device damage.

1-6

As a power sourcing equipment (PSE), the WX3000 series supports the IEEE 802.3af standard while being compatible with some PoE powered devices that do not comply with the 802.3af standard.

The WX3000 series provides power supply through fixed electrical Ethernet ports, with the maximum power transmission distance of 100 meters (328.08 ft.).

Each Ethernet port of the WX3000 series provides a maximum of 25 W output power to the attached PoE powered device. In the case of AC input, the maximum output power with full load of the WX3024 is 370 W, and that of the WX3010 and WX3008 is 125 W; in the case of RPS input, the maximum output power of the WX3024 is 25 W × 24 = 600 W (Note that the RPS output power should be at least 700 W).

Ethernet interfaces

1) Introduction The WX3024 provides twenty-four 10/100/1000Base-T Ethernet ports and four 1000Base-X SFP

ports.

Each SFP port and the corresponding 10/100/1000Base-T Ethernet port jointly form a Combo interface. Only one of the two ports of a Combo interface can be used at a time. Table 1-9 lists the SFP and electrical Ethernet ports that form the Combo interfaces.

The WX3010 provides eight 10/100/1000Base-T Ethernet ports and two 1000Base-X SFP ports.

The electrical Ethernet ports support 10/100/1000 Mbps auto-sensing. The working modes of an Ethernet port at different speeds are shown in Table 1-10.

Table 1-10 Ethernet interface speeds and working modes

Interface speed Working mode

10 Mbps (auto-sensing) Half/full duplex auto-negotiation

100 Mbps (auto-sensing) Half/full duplex auto-negotiation

1000 Mbps (auto-sensing) Full duplex auto-negotiation

The WX3008 provides eight 10/100/1000Base-T Ethernet ports.

The electrical Ethernet ports support 10/100/1000 Mbps auto-sensing. The working modes of an Ethernet port at different speeds are shown in Table 1-10.

The electrical Ethernet port status LEDs are above the RJ-45 sockets. The triangular pointer above each LED indicates which port the LED is for.

The optical Ethernet ports of the WX3000 series support 100/1000 Mbps full duplex. The optical port status LEDs are above the 1000Base-X SFP ports, each indicating the status of the corresponding optical port.

The support for the speed of optical Ethernet ports depends on the model of the optical transceivers.

2) RJ-45 connectors

The 10/100/1000M electrical Ethernet ports of the WX3000 series work with Category-5 twisted pair cables with RJ-45 connectors, as shown in Figure 1-10.

Figure 1-10 RJ-45 connector

3) LC connectors

As an indispensable passive component in a fiber communication system, a fiber connector is mainly used for the removable connection between optical tunnels. This facilitates the testing and maintenance

1-10

of the optical system and makes optical inter-connections more flexible.

Currently, the WX3000 series supports only LC connectors.

Figure 1-11 LC connector

When connecting a networking device using optical fibers, first make sure that the fiber connectors will work with the optical transceivers.

Before connecting fiber cables, make sure that the optical power of the receiver end does not exceed the upper threshold of the receiving optical power of the optical transceiver; otherwise, the optical transceiver may be damaged. For the optical power specifications of the receiver end, refer to Appendix A.

Transceiver Modules

The WX3000 series supports the following optical transceivers:

Optical transceivers are optional components and are not supplied with the WX3000 series. Use H3C-recommended optical transceivers. For details about the technical specifications of SFP optical transceiver, refer to Appendix A.

The WX3024 supports all XFP optical transceivers except those requiring –5.2 V power supply. The BIDI optical transceivers must be used in pairs. For example, if an SFP-GE-LX-SM1310-BIDI

is used at one end, an SFP-GE-LX-SM1490-BIDI must be used at the other end. The same is true for FE BIDI modules.

RPS

When the AC power supply fails, an RPS unit can feed power to maintain the normal operation of the system.

The WX3010 and WX3008 do not support the RPS unit. An RPS unit is an optional accessory to be separately orderly if needed. For the RPS unit installation information, refer to section Connecting the RPS Cable on page 3-19.

2 Preparing for Installation

Safety Precautions

Installation and removal of the unit and its accessories must be carried out by qualified personnel. You must read all of the Safety Instructions supplied with your device before installation and operation.

Installation und Ausbau der Anlage und ihrer Zubehörteile müssen von qualifiziertem Personal realisiert werden. Sie m ü ssen vor der Installation oder Bedienung allen beiliegenden Sicherheitshinweise lesen.

负责安装和日常维护本设备的人员必须具备安全操作基本技能。在操作本设备前，请务必认真阅读和执

行产品手册规定的安全规范。

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

Pull the power plug(s) out of the device before cleaning the device. Do not clean the device using wet cloth or liquid.

Keep the device away from water or dampness. Prevent water or moisture from entering the device chassis.

Do not place the device on an unstable case or desk. The device might be damaged severely in case of a fall.

Ensure proper ventilation in the equipment room and keep the vents of the device free of obstruction.

Make sure that the operating voltage is within the range as labeled on the device. To avoid electrical shocks, do not open the chassis when the device is operating or when electrical

hazards are present. When replacing interface modules, always wear an ESD-preventive wrist strap.

2-2

Installation Site Checking

The device is designed for indoor use. You can mount the device either in a rack or on a workbench, but make sure that:

Adequate space is reserved at the air inlet and exhaust vents for heat dissipation. The rack or workbench has a good ventilation system. The rack is sturdy enough to support the device and its accessories. The rack or workbench is well grounded.

To ensure normal operation and a long service life of your device, install it in an environment that meets the following requirements.

Temperature and Humidity

The temperature and humidity in the equipment room must be kept within a proper range.

Lasting high humidity may lead to bad insulation, electricity creepage, mechanical property changes, and corrosion.

If the relative humidity is too low, captive screws may become loose as a result of contraction of insulation washers, and static electricity may be produced in a dry environment to interfere the circuits on the device.

Lasting high temperatures accelerate the aging of insulation materials and thus significantly lower the reliability and service life of the device.

The temperature and humidity requirements for the WX3000 series are listed in Table 2-1.

Table 2-1 Working environment

Item Specification

Temperature 0°C to 45°C (32°F to 113°F)

Relative humidity 5% to 95% (noncondensing)

Cleanliness

Dust is hazardous to the operating safety of the device. Dust buildup on the chassis may result in static adsorption, causing poor contact of metal connectors or metal contact points. When the relative indoor humidity is low, especially, electrostatic adsorption is more likely to happen. This not only shortens the service life of your device but also causes communication failures. The following table lists the dust concentration limit in the equipment room.

Table 2-2 Dust concentration limit in the equipment room

Physical active substance Limit (particles/m3)

Dust particles ≤ 3 × 104 (No visible dust on the tabletop over three days)

Note: The dust particle diameter is ≥ 5 μm

In addition, the equipment room should also meet the rigorous limits on salts, acids, and sulfides to eliminate corrosion and premature aging of some parts. Table 2-3 lists the limits on harmful gases in the equipment room.

2-3

Table 2-3 Limit on harmful gases in the equipment room

Gas Limit (mg/m3)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

ESD Prevention

Static electricity generation and harms

The electrostatic induction that adversely affects the operation of the device mainly comes from:

Outdoor electric fields caused by high-voltage power lines or lightning strikes. Internal systems, such as the indoor environment, floor materials, and the structure of the

integrated equipment.

Although a great deal of electrostatic discharge (ESD) prevention considerations have been taken in the design of the WX3000 series, excessive static electricity is still remarkably harmful to the whole device.

ESD prevention methods

To prevent ESD damage, do the following:

Make sure that the device and the floor are well grounded. Keep the equipment room clean. Keep proper temperature and humidity conditions. When touching a circuit board, always wear ESD-preventive gloves or an ESD-preventive wrist

strap, and wear antistatic work clothes. When mounting, removing, observing, or moving an interface module, always take the printed

circuit board (PCB) by the edges without touching the components on the PCB. After removing an interface module, place the PCB on an antistatic workbench with the

component-side facing upward or place it in an antistatic bag.

ESD-preventive wrist strap

The ESD-preventive wrist strap is not provided with the device.

Follow these steps to use an ESD-preventive wrist strap:

Step1 Put on and fasten the wrist strap and make sure the wrist strap has good skin contact.

Step2 Attach grounding wire to the wrist strap and the alligator clip to the rack.

Step3 Verify that the rack is well grounded.

2-4

Figure 2-1 Wear an ESD-preventive wrist strap

EMI Prevention

All interference sources, from the outside or inside of the device and application system, adversely affect the device in the conduction patterns of capacitance coupling, inductance coupling, electromagnetic wave radiation, and common impedance (including grounding system) coupling, and cable conduction (including power cables, signal cables and output cables). To prevent interference, do the following:

Use a TN system for the system earthing of the AC power supply, and use a single-phase three-wire AC socket with a protection earth (PE) to effectively filter interference from the power grid.

Keep the device away from high-power radio transmitters, radars, and high-frequency heavy-current devices.

Take electromagnetic shielding measures when necessary. For example, use shielded interface cables.

Route the interface cables only indoors to protect signal interfaces against over-voltage or over-current conditions cause by lightning strikes.

Laser Safety

The WX3000 series is the Class 1 laser product.

Do not look directly at any working optical transceivers on the WX3000 series because the high-energy laser beam emitted from the optical fiber may hurt your eyes.

Staring into the laser beam emitted from an optical fiber may hurt your eyes.

3-15

Select the installation location carefully. In the case of poor surface, magnet mounting may not be reliable.

Put the device at a stable place free from vibrations or shocks. Otherwise, personal injuries or equipment damage may occur.

Avoid installing the device at a high place because personal injuries or equipment damage may occur in case of a falloff.

Avoid frequently moving the desk-mounted device because such movements may damage the surface coating.

Keep the front panel of the device facing downwards and the two sides with ventilation holes vertical to the ground, if you want to install the device vertically.

Pay attention that the weight of external cables should not bring about a falloff, which may result in personal injuries or equipment damage.

Keep floppy disks and magnetic cards away from magnets to avoid erasure of any information. Keep computers and monitors that are easily influenced by magnetic fields away from magnets.

Otherwise, faults may occur to these electronic devices. The power cords may vary with different standards of different countries, so you may need to select

a bail latch as needed.

Connecting the Ground Cable

The correct connection of the protection ground cable of the device is an essential safeguard against lightning strokes and interference. You must correctly connect the ground cable before using your device.

The power input end of the device has a noise filter, whose central ground is directly connected with the chassis, forming the protection ground (PGND) of the chassis. This chassis ground must be securely earthed so that the induction and creepage currents can be safely discharged to the earth to enhance the anti-EMI capability of the device. The following describes how to connect the PGND cable in different situations.

If a grounding strip is available

Attach one end of the yellow-green PGND cable of the device to the grounding screw on the chassis and the other end to the grounding terminal on the grounding strip and fasten the nut.

3-16

Figure 3-23 Connect the PGND cable when a grounding strip is available

(1) AC power receptacle (2) Grounding screw (3) PGND cable (4) Grounding strip in the equipment room

The fire main and the lightning rod of the building are not good grounding options. The PGND cable of the device should be connected to the earthing system of the equipment room.

Without a grounding strip

1) If an area with exposed earth is available nearby where a grounding conductor can be buried

Hammer a 0.5 m (1.64 ft.) or longer angle iron or steel tube longer into the earth. Weld the yellow-green grounding cable to the angle iron or steel tube, and treat the joint for corrosion protection.

5 Maintaining Software

Because the display information of the WX3010, WX3024 and WX3008 are similar, this chapter takes the WX3024 as an example.

Introduction

Files Managed by the Device

The WX3000 series consists of two virtual systems: access control engine and switching engine, for which two independent file systems are employed to manage the following four types of files:

BootWare program file Application files Configuration files Web files

The access control engine manages the BootWare program file and application files; the switching engine manages the Web files; both the access control engine and switching engine store and manage their respective configuration files.

BootWare Program File

The BootWare program file is used to boot applications during the startup of the device. A complete BootWare program file includes a basic section and an extended section.

The basic BootWare section is used to complete the primary initialization of the system. With rich human-computer interaction (HCI) functions, the extended BootWare section is used for

initializing the interfaces and updating the applications and the boot system. A complete BootWare program is the combination of the basic and extended BootWare sections.

After the basic BootWare section is started, you can download and update the extended BootWare through the menu of the basic BootWare section.

Do not power off or restart the device when updating the BootWare program file; otherwise, the BootWare program may be damaged and the device may fail to operate normally.

5-2

Application Files

The WX3000 series supports the Dual Image function. By default, the system defines three application files for system boot:

Main application file (referred to as main file) Backup application file (referred to as backup file) Secure application file (referred to as secure file)

These three application files are stored in the flash memory, with the file name extension of .bin.

Typically, the default application files are written into the built-in flash memory before device delivery.

If you have uploaded all the three types of application files in the flash memory, the system uses these three files to boot the device in the sequence of main.bin, backup.bin, and secure.bin. For how to set the type of an application file, refer to section Maintaining the Application and Configuration Files on page 5-22.

The following gives the default names and types of the application files and their priorities for booting:

Main application file. The default name is main.bin and the file type is M. it is the default application file for system boot.

Backup application file. The default name is backup.bin and the file type is B. If the system fails to boot using the main application file, it tries the backup application file.

Secure application file. The default name is secure.bin and the file type is S. If the system fails to boot using the backup application file, it tries the secure application files. If the system fails to boot using the secure file, it gives a startup failure message.

Note that:

Only the application files of the M, B, and S types can be used to boot the system, while an application file of the N type (an application file other than the M, B, or S type) cannot.

You can rename the application files in the flash memory through the command line interface (CLI) after the application program is loaded. You can modify the file type of the M, B, and N types application files through the BootWare menu or the CLI after application startup, while you cannot modify the file type of the S-type application file.

The secure application file is the last resort for system boot; therefore, you cannot change the file type of the secure application file or turn another type of file into a secure file by modifying the file type. The secure file can only be downloaded from the BootWare menu.

Only one file of the same type (M, B, or S) can exist in the flash memory at a time. For example, if an application file of type M+B exists in the CF card, another file of type M or B cannot exist. If the type of another file is changed to B, the existing type M+B file changes to a file of type M.

Configuration Files

With the file name extension of .cfg, configuration files are used to store the configuration information of the device. Typically, no configuration file with the name extension .cfg is provided when the device is delivered (a configuration file with name extension .def is provided by the switching engine). In this case, the device loads the default configuration at startup. If the configuration file is deleted or missing, the device also loads the default configuration at reboot.

The access control engine has only one configuration file with no backup. The switching engine has main and backup configuration files, which are managed like the

application files on the access control engine.

5-3

The length of a configuration file name must not exceed 64 characters (including the drive identifier and the string terminator). For example, if the drive identifier is flash: /, the maximum length of a file name is [ 64 – 1 – 5 ] = 58 characters.

If the length of a file name exceeds 58 characters, operations on that file will fail. It is recommended to keep a file name within 16 characters.

There is a limitation on the length of file name that can be displayed in BootWare. If a file name is shorter than 30 characters, all the characters of the file name can be displayed; if a file name has or exceeds 30 characters, only the first 26 characters of the file name can be displayed, followed by a tilde (~) and a serial number. This serial number identifies the position in sequence of the file. For example, if file A, file B and file C have a file name longer than 30 characters, the name of file A will appear as the first 26 characters plus ~001, that of file B will appear as the first 26 characters plus ~002, and that of file C will appear as the first 26 characters plus ~003.

Web Files

Web files are used by the switching engine to provide Web-based functions, and are released with version releases (each version has a default Web file). You are not recommended to modify the file name and settings.

Web files fall into main and backup files, and are managed like the application files on the access control engine.

Approaches for Software Maintenance

You can maintain the device in either of the following two ways:

Update BootWare and application files using the XMODEM protocol through a serial port. Update BootWare and application files using the TFTP/FTP protocol via an Ethernet port through

the BootWare menu or the CLI.

The BootWare program is updated together with the Comware application. When you update the Comware application to the latest version, the BootWare is updated to the latest version automatically.

Before updating the software, check the current version of BootWare and that of the application program to make sure that the correct file is used for the update. For the association between the host software version and the BootWare version, refer to the hardware and software compatibility matrix in Release Notes.

Updating Software Through a Serial Connection

Introduction to XMODEM

To update BootWare and applications through a serial connection, use the XMODEM protocol.

XMODEM is a file transfer protocol that is widely applied due to its simplicity and good performance. XMODEM transfers files through serial ports. It supports two types of data packets (128 bytes and 1 KB), two check methods (general checksum and CRC), and error packet retransmission mechanism (generally the maximum number of transmission attempts is ten).

The XMODEM transmission procedure is completed by the cooperation of a receiving program and a sending program. The receiving program sends a negotiation packet to negotiate the packet check

5-8

method. After the negotiation, the sending program starts to send data packets. When receiving a complete packet, the receiving program checks the packet using the agreed method.

If the check succeeds, the receiving program sends an acknowledgement (ACK) character and the sending program proceeds to send another packet.

If the check fails, the receiving program sends a negative acknowledgement (NAK) character and the sending program retransmits the packet.

Modifying Serial Communication Parameters

Sometimes, we need a high serial port baud rate to save the update time, or a lower baud rate to ensure the transmission reliability. This section introduces how to adjust the serial communication baud rate.

Enter the BootWare main menu, select 2 to enter the serial submenu, and then select 5 to modify the baud rate. The system displays the following:

=================================<BAUDRATE SET>============================

|Note:'*'indicates the current baudrate |

| Change The HyperTerminal's Baudrate Accordingly |

|---------------------------<Baudrate Available>---------------------------|

|<1> 9600(Default)* |

|<2> 19200 |

|<3> 38400 |

|<4> 57600 |

|<5> 115200 |

|<0> Exit |

===========================================================================


Select an appropriate downloading rate. If you want to a 115200 bps download rate, for example, enter 5. Then the system displays the following information:

Baudrate has been changed to 115200 bps.

Please change the terminal's baudrate to 115200 bps, press ENTER when ready.

Now that the serial communication baud rate of the device has been changed to 115,200 bps while that of the terminal is still 9,600 bps, the two sides cannot communicate with each other. Change the baud rate to 115,200 bps in HyperTerminal.

Updating Applications Through a Serial Connection

To update an application file through a serial connection, you need to enter the serial submenu. Select 2 from the BootWare main menu to enter the serial submenu. For details about this submenu, refer to section Serial submenu on page 5-6.

You can modify the serial interface baud rate to accelerate the file update. For details, refer to section Modifying Serial Communication Parameters on page 5-8. Select 2 from the serial submenu. The following information appears:

5-13

Please Start To Transfer File, Press <Ctrl+C> To Exit.

Waiting ...CCCCCCCCCC

Select and send the appropriate application file in HyperTerminal. The procedure for updating an application file through a serial connection is the same as updating the BootWare program. For details, refer to section Updating BootWare Through a Serial Connection on page 5-10.

Typically, the size of an application program is over 10 MB. Even at a serial baud rate of 115,200 bps, the update takes about 30 minutes. Therefore, you are recommended to update an application program through an Ethernet port.

Updating Applications Using TFTP

To update a large application file, use the Trivial File Transfer Protocol (TFTP), which can remarkably shorten the software maintenance time.

TFTP is a TCP/IP protocol used for file transfer between client and server. It provides a simple and low-overhead file transfer service. TFTP provides unreliable data transfer over UDP and does not provide any access authorization and authentication mechanism. It employs the timeout retransmission method to implement best-effort delivery of data.

The WX3000 series provides TFTP Client service. That is, with the device serving as the TFTP client and the file server serving as the TFTP server, you can upload application files from the device to the file server, or download application files from the file server to the device.

You can update an application file using TFTP through either the BootWare menu or the CLI.

Updating an Application Using TFTP Through the BootWare Menu

Setting up an update environment

Figure 5-7 Set up a TFTP environment

5-14

Step1 Connect the Ethernet interface GigabitEthernet 1/0/1 of the device to the PC using a crossover Ethernet cable, and configure IP addresses for the Ethernet interface of the device and the PC, which must be on the same network segment so that the device and the PC can communicate with each other. For example, set the IP address of the VLAN interface to 192.168.0.1 and that of the PC to 192.168.0.2.

Step2 Run TFTP Server on the PC, and set the path of the application file to be downloaded.

The TFTP server software is not provided with the WX3000 series. You must make sure that it is available by yourself.

On the WX3000 series, only the management Ethernet interface, namely GigabitEthernet 1/0/1 can be used for application update.

Configuring the Ethernet interface parameters

Before updating an application file through the management Ethernet interface, you need to configure the interface as follows:

Select 3 from the BootWare main menu to enter the Ethernet submenu and select 5 to enter the Ethernet interface configuration submenu.

============================<ETHERNET PARAMETER SET>===========================

|Note: '.' = Clear field. |

| '-' = Go to previous field. |

| Ctrl+D = Quit. |

===============================================================================

Protocol (FTP or TFTP) :tftp

Load File Name :main.bin

Target File Name :main.bin

Server IP Address :192.168.0.2

Local IP Address :192.168.0.1

Gateway IP Address :

FTP User Name :

FTP User Password :

When configuring a parameter, you can enter a new value directly, or press Enter to accept the default value that follows a colon. You can type . to clear the current input, - to return to the previous parameter field, and Ctrl+D to quit from the parameter configuration interface.

5-15

Updating an application file

After configuring the Ethernet interface parameters, select 3 from the BootWare main menu to enter the Ethernet submenu and then select 2. In this example you update the main application file. The following information appears:

Loading...............................................................................

......................................................................................

.................................Done!

......................................................................................

......................................................................................

.................................................................Done!

Finalizing application update

Select 0 to return to the BootWare main menu, and then press 1 to reboot the system.

If you specify a filename that already exists in the flash memory, the system prompts The file is exist,will you overwrite it? [Y/N] If you select Y, the existing file will be overwritten.

Make sure that sufficient space is available in the flash memory. In case of insufficient space, the update cannot proceed and the system will give an error prompt.

The new application file replaces the existing file of the same type, if any, and becomes the only application file of that type. In this example, main.bin replaces the application file with the attribute of M and becomes the only main application file.

For details about the file types, refer to Introduction on page 5-1.

Updating and Backing Up an Application Using TFTP Through the CLI

The access control engine and the switching engine have separate file systems. You need to log in to the CLI of a specific system before you can do file operations in it.

After the device starts, you are directly logged in to the access control engine system. To enter the switching engine system, use the oap connect slot 0 command; to log out, press Ctrl + K.

5-16

The application files are managed only on the access control engine. On the CLI of the access control engine, you can change to the CLI for the switching engine

through the oap command and perform operations on the configuration files and Web files on the switching engine.


Set up a software update environment and specify the working path of the server. For details, refer to section Setting up an update environment on page 5-13.

For operations on the access control engine, the data needs to be transferred from the switching engine to the access control engine; therefore, you need to configure the IP addresses of the switching engine, access control engine and the PC to be in the same network segment. For example, configure the IP address of the TFTP server as 192.168.0.1, that of the access control engine of the device as 192.168.0.2, and that of the switching engine as 192.168.0.3 (to configure the IP address of the switching engine, you need to change to CLI of the switching engine by using the oap command). Verify the connection by using the ping command.

For operations on the switching engine, you need to log in to the switching engine using the oap command, configure the IP addresses as mentioned above, and verify the connection by using the ping command.

The IP addresses of the access control engine and switching engine are both configured in VLAN interface view.

Backing up and restoring application and configuration files

After setting up the environment, do the following on the terminal:

Use the dir command to check what files are in the file system:

<System>dir

Directory of flash:/

0 -rw- 855 Jul 26 2007 08:22:56 startup.cfg

1 -rw- 19189956 Jul 28 2035 10:35:38 main.bin

60884 KB total (41991 KB free)

<System>

For example, to copy the file startup.cfg on the device and save it as config.bak on the TFTP server, use the following command:

5-17

<System>tftp 192.168.0.1 put startup.cfg config.bak

File will be transferred in binary mode

Sending file to remote TFTP server. Please wait... \

TFTP: 855 bytes sent in 0 second(s).

File uploaded successfully.

To download config.cfg from the server to the device, use the following command:

<System>tftp 192.168.0.1 get config.cfg statup.cfg

The file statup.cfg exists. Overwrite it?[Y/N]:y

Verifying server file...

Deleting the old file, please wait...

File will be transferred in binary mode

Downloading file from remote tftp server, please wait...\

TFTP: 855 bytes received in 0 second(s)

File downloaded successfully.

If a file with the same name exists on the device, the device will prompt you whether to overwrite the existing file. You can choose Y to overwrite it or N to abort.

When you back up a file to the server, the existing file with the same name on the server, if any, will be replaced without a prompt.

The operations mentioned above are to be performed in user view. You can modify the backup configuration file with a text editor and then download the modified file

to update the configuration. The update takes effect upon system reboot. Likewise, you can download the application file to the device and overwrite the existing main application file to update the application.

Updating Applications Using FTP

If the application file to be downloaded has a large size, you can use the File Transfer Protocol (FTP) to save the software maintenance time.

FTP is an application-layer TCP/IP protocol used for file transfer between a server and a client. It provides reliable, connection-oriented data transfer service over TCP.

You can update an application using FTP in two ways:

Through the BootWare menu. In this approach, the device must serve as an FTP client. Through the CLI. In this approach, the device can serve as either an FTP server or an FTP client.

5-18

Updating an Application Using FTP Through the BootWare Menu


Figure 5-8 Set up an environment, with the device as an FTP client

Connect the Ethernet interface GigabitEthernet 1/0/1 of the device to the PC using a crossover Ethernet cable, and configure IP addresses for the Ethernet interface of the device and the PC, which must be on the same network segment so that the device and the PC can communicate with each other. For example, set the IP address of the VLAN interface to 192.168.0.1 and that of the PC to 192.168.0.2.

Run the FTP Server on the PC and set the path of the application file to be downloaded, FTP username and password.

The FTP server software is not provided with the WX3000 series. You must make sure that it is available by yourself.

On the WX3000 series, only the management Ethernet interface, namely GigabitEthernet 1/0/1 can be used for application update.

For the rest steps, refer to section Configuring the Ethernet interface parameters on page 5-14, section Updating an application file on page 5-15, and section Finalizing application update on page 5-15.

Updating and Backing Up an Application Using FTP Through the CLI

With the device as an FTP server and the PC acting as an FTP client

1) Set up an update environment

Figure 5-9 Set up an environment, with the device as an FTP server

For operations on the access control engine, the data needs to be transferred from the switching engine to the access control engine; therefore, you need to configure the IP addresses of the switching engine, access control engine and the PC to be in the same network segment. For example, configure the IP address of the FTP client as 192.168.0.1, that of the access control engine of the device as 192.168.0.2, and that of the switching engine as 192.168.0.3 (to configure the IP address of the switching engine, you need to change to CLI of the switching engine by using the oap command). Verify the connection by using the ping command.


2) Enable the FTP server

The FTP server feature supports concurrent access of multiple clients. Upon receiving a request from an FTP client, the FTP server performs the requested operation and returns the result. Use the following command to enable FTP server:

[System]ftp server enable

% Start FTP server

Add an authorized FTP username and password:

[System]local-user guest // Create user account guest

[System-luser- guest]service-type ftp // Set the user type to FTP

[System-luser- guest]password simple 123456 // Set the password to 123456

3) Maintain the device

After enabling FTP server and setting the username and password on the device, start the FTP client application on the PC. This example assumes that you use Microsoft FTP Client provided in Windows XP.

Open a DOS prompt window, and enter ftp at the DOS prompt.

C:\Documents and Settings\Administrator>ftp

Updating Web Files on the Switching Engine

If the application program is successfully upgraded and the switching engine has upgraded Web files, the Web files are automatically upgraded after the system reboots (manual upgrade is not recommended). During the starting process of the switching engine, the device searches files with the suffix of .web in the file system. Such Web files are named h3c-http3.1.9-000X.web, in which X varies with versions. If no such a file is available in the file system, the device loads it from the application program file package. After the system is rebooted, the Web file in the file system is displayed as follows:

<System>dir

Directory of unit1>flash:/

1 (*b) -rw- 957976 Apr 02 2000 00:44:15 h3c-http3.1.9-0001.web

2 -rw- 296 Apr 01 2000 23:56:03 config.def

Dealing with Password Loss

This section describes how to deal with password loss.

BootWare Password Loss

If you have forgotten the BootWare password, contact your local dealer. The technical support staff will help you log in to the system and set a new password.

To change the BootWare password, enter the BootWare main menu, select 5, and follow the instructions. The following information is displayed on the terminal:

please input old password:

Please input new password:

Please input new password again:

Password Set Successfully.

Once you enter a wrong old password or different new passwords, the password modification operation fails and the system exits this operation.

A BootWare password can contain up to 32 characters, including printable characters such as letters, numerals, and punctuations.

User Password Loss

Your login will be refused if you have forgotten the user password. In this case, set a new user password by following the steps below:

5-25

1) Select 6 from the BootWare main menu to start the system without loading the system configuration.

The following information appears:

Flag Set Success.

2) When the BootWare main menu appears again, select 0 to restart the system. System starts booting …

3) Set a new password in system view. <System>system-view

[System]user-interface aux 0

[System-ui-aux0]authentication-mode password

[System-ui-aux0]set authentication password simple 123456

This means that password authentication is required for console port login, and the password has been set to 123456 in plain text.

Upon reboot, the system runs with the default configuration, with the configuration file stored in the flash memory. To restore the original configuration, use the display saved-configuration command to view the contents of the configuration file, copy them and run them.

If the password is stored in plain text, you can use the display current-configuration command to view the password in the current configuration. If you use the set authentication password cipher 123456 command to set your password, the password will be stored in cipher text.

4) Save the new configuration. [System] save

After modifying the user password, use the save command to save it.

Super Password Loss

The super password allows you to switch between four super levels. Without a super password, you cannot perform higher privilege operations.

Select 8 from the BootWare main menu to clear the super password.

6 Troubleshooting

Troubleshooting Software Loading Failure

If software loading fails, the system runs the old version of the software. In this case, check if the physical ports are properly connected.

If the ports are not properly connected, reconnect them correctly and restart the loading process. If the ports are properly connected, check the loading process information displayed on

HyperTerminal for input errors. In case of any input errors, restart the loading process with correct inputs.

Input errors include:

A baud rate other than 9600 bps selected for BootWare loading using XMODEM. An improper baud rate setting in HyperTerminal. A wrong IP address, file name, or TFTP Server work path specified for software loading using

TFTP. A wrong IP address, file name, username, or password specified for software loading using FTP.

If the case cannot be located, contact your local dealer for help.

Troubleshooting the Power System

For the WX3024, you can check whether the power system of the device has failed by viewing the RPS LED and PWR LED on the front panel; for the WX3010 and WX3008, you can check whether the power system of the device has failed by viewing the PWR LED on the front panel. When the power supply functions normally, the RPS LED stays on or the PWR LED is blinking green. If the RPS LED is off or the PWR LED is solid red, check whether:

The device power cable is properly connected; The power input to the device meets the requirements.

Troubleshooting the Configuration System

If the device is operational upon power-on, the configuration terminal displays the boot information; otherwise, you may see nothing or illegible characters on the configuration terminal.

No display on the terminal

If there is no output information after the device is powered on, check whether:

The power supply is normal; The console cable is properly connected.

If the cause cannot be located in the steps above, check whether:

The console cable is in good condition. Terminal settings are correct.

BIDI optical transceivers use different central wavelengths in the transmitting and receiving directions, and thereby support bi-directional transmission of optical signals through the same fiber.

The BIDI modules must be used in pairs. If an SFP-GE-LX-SM1310-BIDI is used at one end, an SFP-GE-LX-SM1490-BIDI must be used at the other end.

Appendix B Installation of Lightning Arrester for

Network Interfaces

You can install a lightning arrester only for the 10M/100M electrical Ethernet interfaces supporting RJ-45 connectors.

No lightning arrester for network interface is supplied with the switch.

If an outdoor network cable should be directly led to the switch, please serially connect the lightning arrester for the network interface before you plug this cable into the switch, thus to prevent possible damages to the switch due to lightning strike.

Tools

Philips or flat-blade screwdrivers Multimeter Diagonal cutting plier

Installation Procedure

1) Remove the protective paper on one side of the double-faced adhesive tape and stick it on the shell of the arrester, remove the protective paper on the other side and stick the arrester on the chassis of the switch. Keep the arrester as close to the grounding screw of the switch as possible.

2) Cut the ground cable of the arrester of a suitable length according to the distance between the arrester and the grounding screw and then fasten the cable on the grounding screw tightly.

3) Use the multimeter to verify whether the ground cable of the arrester has a close touch with the grounding screw and chassis of the switch.

4) Follow the instruction of the arrester to connect the arrester for network interface with a transit cable. Pay attention to the direction: IN end of the cable is connected to the arrester while OUT end of the cable is connected to the switch. After the connection, check whether the LEDs of the interface modules are normal.

Technical parameters, installation and maintenance methods of an arrester have been given in the arrester instruction. Read the instruction carefully before installing the lightning arrester for the network interface.

5) Tie the cables together with nylon clips.

Precautions

To ensure performance of the lightning arrester for network interface during installation, observe the following rules:

Properly connect the lightning arrester for network interface, with IN connecting to the lightning arrester while OUT connecting to the network interface of the switch.

Correctly ground the lightning arrester. When connecting the ground cable, make sure that the ground cable is of a proper length and has a good touch with the grounding screw of the switch. Check the ground cable with a multimeter after connection.

Install adequate lightning arresters for network interfaces. When there are more than one network interface connecting to outdoor cables, you should install a lightning arrester for each of the network interfaces, thus to guard the interfaces against possible damages.

Appendix C Installation of Lightning Arrester for AC

Power

No lightning arrester (lightning protection grounding strip) is supplied with the switch.

If an outdoor AC power cable should be directly led to the switch, please serially connect the lightning arrester for AC power (lightning protection grounding strip) before you plug AC power cable into the switch, thus to prevent possible damages to the switch due to lightning strike. You can use cable clips and screws to fasten the lightning arrester for AC power on the cabinet, workbench or the wall of the equipment room. When you power on the switch, the AC power flows through the lightning arrester and then into the switch.

Note the following points:

1) Make sure that the PE terminal of the arrester is well grounded before using the lightning arrester for power.

2) Upon plugging the AC power cable connector of the switch into the receptacle of the lightning arrester, if the green LED is on while the red LED does not alarm, it means that the lightning arrester of power is running and the function of lightning protection has taken effect.

3) Pay adequate attention if the red LED is on. You should correctly locate the problem, whether it is caused because the ground cable of the arrester is not well grounded or because the live and zero wires are connected in reverse direction.

4) You may use a multimeter to examine the polarity at the power receptacle of the arrester:

C-2

If the multimeter displays that the left wire is the zero wire and the right is the live wire, it means that the PE terminal of the arrester is not well grounded.

Otherwise, it means that the power receptacle of the arrester is set to the reverse polarity. In this case, open the power receptacle of the arrester and correct the polarity. After that, if the red LED still alarms, it means that the arrester is not well grounded yet.
