SHUTDOWN LEDThe S3500 is equipped with a SHUTDOWN LED (see Figure 9), which serves two functions:

If you execute the halt command from the CLI or the LCD screen, the SHUTDOWN LED will turn red once the system halt is complete.

If the temperature of the S3500 exceeds the temperature threshold, the SHUTDOWN LED is lit. The CPU threshold is 212 ºF (100 ºC).

If any of the components of the S3500 reach the designated temperature threshold, the S3500 will shut itself down to protect itself from damage and the SHUTDOWN LED will illuminate.

Fan TrayThe S3500 is equipped with a field-replaceable, hot-swappable fan tray. Each fan tray features four individual fans that pull air through the chassis from the front and sides through to the rear. Each fan tray can tolerate the failure of a single fan while maintaining a safe operating temperature for the Mobility Access Switch.

Hot Swapping

The S3500 allows you to replace the fan tray while the unit is operable. It is recommended the replacement fan tray be installed immediately to maintain operational temperatures within the unit.

Figure 13 Fan Tray

The S3500 software also sends traps to provide a warning once the system temperature approaches the system tolerance. Additionally, you can monitor the current system status using the CLI or LCD Screen. For more information on traps and system monitoring, see the ArubaOS 7.2 User Guide.

Power Supply

The Aruba S3500 Series Power Supply adapts electrical power for use with the S3500. The chassis has two slots that can hold individual power supplies to support redundancy or load-sharing.

The Aruba S3500 is shipped with one hot-swappable, field-replaceable, AC power supply (350W, 600W or 1050W depending on the SKU) and one blank face plate. The included power supply is installed in the slot PSU 0, while slot PSU 1 has a blank face plate covering the opening. The Mobility Access Switch can operate with one or two active power supplies, depending on the demands of your configuration.

350W Power Supply: This power supply has a single voltage rail, at 12V, and does not support PoE.


Never insert or remove a power supply while the power cord is connected. Verify that the cord has been disconnected from the power supply before installation or removal.


600W Power Supply: This power supply has two voltage rails, one at 12V and the other at 56V, and is capable of supporting PoE.

1050W Power Supply: This power supply has two voltage rails, one at 12V and the other at 56V, and is capable of supporting PoE.

Load Sharing

Load sharing occurs when more than one power supply of the same rating is installed in the S3500 PoE models and the PoE consumption exceeds that of a single power supply. Load sharing divides the total power load of the switch among all available power supplies. Since the power supplies work together, the effective PoE capacity of the switch is increased with each additional power supply.

Redundancy

Redundancy occurs when more than one power supply of the same rating is installed in the S3500 PoE models and the PoE consumption does not exceed that of a single power supply. Redundancy natively occurs in S3500 non-PoE models with more than one power supply of the same rating. With power redundancy, the S3500 can continue normal operation even when a power supply fails or is turned off. When both the power supplies are installed, if one becomes unavailable (fails, or is turned off or removed) the other power supply will attempt to provide full power for the device.

Hot Swapping

Hot swapping allows you to replace one failed power supply while the other provides full power. This makes it unnecessary to shut down the S3500 during the replacement procedure.

Modules

The 350W, 600W, and 1050W power supplies are autosensing, load-sharing, redundant power supply modules that support an input voltage of 100 VAC to 240 VAC. Each power supply has a country-specific power cord for connection to an AC power outlet.

The 600W and 1050W power supply modules are not supported in the S3500-24F. Although the S3500-24F will continue to operate with these supplies, an ArubaOS alarm will be sent until the supplies are replaced with a 350W power supply.

LEDs

Each power supply is equipped with three LEDs to help monitor the status of the power supply module.

Monitoring

In addition to the LEDs on the power supplies, the power supply status can be monitored through the CLI and the LCD Screen, as well as traps sent when a power supply fails.

From the Status menu on the LCD Screen, you can view the status of each power supply slot. The LCD Screen will display the slot number followed by one of three statuses: OK, FAILED, or MISSING.

OK: The power supply is operating normally

FAILED: The input power is not connected or the power supply has stopped operating (replace the power supply).

MISSING: No power supply is installed in this slot

For information on how to access the Status menu, see“LCD Panel” on page 14.

PoE

The S3500 "P" SKUs support PoE (802.3af) and PoE+ (802.3at) to provide power to connected devices such as Access Points and IP Phones. PoE/PoE+ is enabled by default to provide plug and play capability for PoE capable devices. The S3500 has three PoE Management Modes:

Dynamic Mode: This the default mode. The per port power budgeted from the total power supplied from the PSUs is equal the amount of power consumed by the port.

Static Mode: The amount of power used by a specific port is the maximum power configured on that port by the user. This mode ensures that the maximum power specified by the user is reserved and not shared with other ports.

Class-based Mode: The power allotted to the port is the maximum amount of power for the class of powered device connect to that port.

The S3500 "P" SKUs require at least one 600W power supply. Each power supply allocates 200W for non-PoE system functions. This applies to each power supply. Therefore, if you have two power supplies installed, a total of 400W is set aside for non-PoE system use.

For more information on monitoring the power supplies, see the ArubaOS 7.2 User Guide and the ArubaOS 7.2 CLI Reference Guide.


In addition to the 600W power supply, a 1050W power supply is available for use with PoE capable S3500s. The type and number of power supplies installed in your S3500 will determine the amount of power available for PoE and the number of PoE capable ports. The following table describes the possible power supply configurations available for a PoE capable S3500.

PoE Priority

If the S3500 experiences a reduction in power while the entire power pool is being used, the S3500 will begin disabling ports based on port priority until the required power is available again. Ports with a lower priority will stop receiving power before ports of a higher priority. Port priority can be configured by the user to ensure that necessary devices have power whenever possible. However, if any number of ports have the same priority, ports with the higher interface number will stop receiving power first.

For example:

If interface 0/0/4 and interface 0/0/10 have the same priority but there is not enough power for both, the S3500 will eliminate 0/0/10 first.

Upgrade your Mobility Access Switch to the most recent software release. Stacking requires ArubaOS 7.1 or newer. All the members of an ArubaStack must run the same version of ArubaOS.


The ArubaStack feature enables simplified management by presenting a set of Mobility Access Switches as one entity, and reduces the operational complexity of managing multiple redundant links between access and distribution layer switches. Since the stack appears as one network node, loop prevention protocols are not required.

An ArubaStack is a set of interconnected Mobility Access Switches using stacking ports to form a stack. A stacking port is a physical port provisioned to run the stacking protocol. In factory default settings for Mobility Access Switches, the uplink ports 2 and 3 on the uplink module are pre-provisioned to be stacking ports. Once a port is provisioned for stacking, it is no longer available to be managed as a network port. A stacking port can only be connected to other Mobility Access Switches running the Aruba Stacking Protocol (ASP).

The Aruba Stacking Protocol Each Mobility Access Switch runs a stack manager process that is responsible for running ASP. The Stacking protocol is responsible for automatically:

Identifying the stack neighbors and determining the stack topology.

Assigning the switch’s member ID to each member of the stack.

Assigning each member of the stack a role; Primary, Secondary or Line Card.

Setting up optimized communication path/channel between the stack members. This path/channel transports user data packets and the switch’s own control packets.

Converges the stacking topology during a stack link or stack member failure event; users and traffic are automatically re-routed via a different path.

Auto Discovery

ASP exchanges information between Mobility Access Switches that are connected to each other and without any prior stacking related configuration. The protocol exchanges information between the different stack members, runs distributed election algorithm, and elects a Primary and Secondary members among the stack members. The Primary then assigns stack member IDs to himself others.

Planning a StackAruba recommends using a ring topology (Figure 37) for a stack consisting of Mobility Access Switches. This configuration provides connectivity to all members as well as redundancy in the event a cable failure.

Consider the following while planning your stack:

ArubaOS supports up to eight Mobility Access Switches in a single stack. The stack can be a mixture of 24/48 port S3500 and S2500 Mobility Access Switches.

Cable Length: Depending on your configuration, you might need cables of different length.

The sequence in which you initially power on the Mobility Access Switches in your stack determines their member ID. For example, the first Mobility Access Switch to boot up is assigned member ID 0 and the second Mobility Access Switch is assigned member ID 1. Therefore, if you want your Mobility Access Switches to be assigned particular IDs, power them on in that order.

All values and setting described in the following sections are the default values and settings.


Creating a Stack To create a stack:

1. Power off your Mobility Access Switch.

2. Ensure that you have installed an uplink module in each Mobility Access Switch that will become part of the stack. If you have not installed an uplink module, see “Installing an Uplink Module” on page 44.

3. Rack mount each Mobility Access Switch by following the steps described in Chapter 2, “Installation” on page 27.

4. Insert SFPs or DACs into the stack ports. See “Installing an SFP/SFP+” on page 45 or “Installing a Direct Attach Cable” on page 47 for more information.

5. Power on your Mobility Access Switches.

6. Once all the Mobility Access Switches have booted up, execute the show stacking members and show

stacking topology commands to view stack member assignments.
