General Safety Instructions The following instructions serve as a general guide for the safe installation and operation of telecommunications products. Additional instructions, if applicable, are included inside the manual.

Safety Symbols

This symbol may appear on the equipment or in the text. It indicates potential safety hazards regarding product operation or maintenance to operator or service personnel.

Danger of electric shock! Avoid any contact with the marked surface while the product is energized or connected to outdoor telecommunication lines.

Protective earth: the marked lug or terminal should be connected to the building protective earth bus.

Some products may be equipped with a laser diode. In such cases, a label with the laser class and other warnings as applicable will be attached near the optical transmitter. The laser warning symbol may be also attached. Please observe the following precautions: Before turning on the chassis with optic module, make sure that the fiber optic cable is intact and is connected to the transmitter. Do not attempt to adjust the laser drive current.

Do not use broken or unterminated fiber-optic cables/connectors or look straight at the laser beam.

The use of optical devices with the equipment will increase eye hazard. Use of controls, adjustments or performing procedures other than those specified herein, may result in hazardous radiation exposure. ATTENTION: The laser beam may be invisible!

Always observe standard safety precautions during installation, operation and maintenance of this product. Only qualified and authorized service personnel should carry out adjustment, maintenance or repairs to this product. No installation, adjustment, maintenance or repairs should be performed by either the operator or the user.

All extension slots are not hot-swappable

Before operating modules in the electricity conditions, please be noticed that optical transceivers shall be connected with optical fiber wires or shield with optical transceiver cover for fear that laser light harms to operators eyes.

Handling Energized Products

General Safety Practices Do not touch or tamper with the power supply when the power cord is connected. Line voltages may

be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist. Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any other metallic object that may come into contact with energized parts. Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug is provided on the product, it should be connected to the protective earth at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and cabinets. Always make the ground connection first and disconnect it last. Do not connect telecommunication cables to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the ground.

Connection of AC Mains Make sure that the electrical installation complies with local codes. Always connect the AC plug to a wall socket with a protective ground. Always connect the power cord first to the equipment and then to the wall socket. If a power switch is provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the building installation.

Connection of DC Mains Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground. Any single pole can be externally grounded. Due to the high current capability of DC mains systems, care should be taken when connecting the DC supply to avoid short-circuits and fire hazards. DC units should be installed in a restricted access area, i.e. an area where access is authorized only to qualified service and maintenance personnel. Make sure that the DC supply is electrically isolated from any AC source and that the installation complies with the local codes. Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position. When connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the positive pole and last the negative pole. Switch the circuit breaker back to the ON position. A readily accessible disconnect device that is suitably rated and approved should be incorporated in the building installation.

Preventing Electrostatic Discharge Damage

Modules which can be plugged into chassis are sensitive to damage from static electricity. Conversely, static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines: Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact. When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. Avoid contact between the component and your clothing. The wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage. Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag. Handle Modules by the metal card carrier edges only; Avoid touching the board or any connector pins.

Appendix C FAQ

For some problems you may meet during installation and operation, please try to solve them following the suggestions below. For the problems can not be solved using the following suggestions, please contact with distributors for technical support.

The power supply indicator PWR (green) wouldnt turn ON. Please check whether the power supply cable of the device is well connected and whether the power supply switch has been turned on.

The optical interface LOSA or LOSB indicator (red) turns ON.

This indicates that loss of receiving signal (LOS) alarm occurs at the optical interface. Firstly, please check whether the fiber is well connected to the optical interface.

Secondly, please form a self loop using the fiber (may need attenuation). If the alarm still exists, please replace the fiber and again form a self loop using the new fiber. If the optical interface LOS indicator is still ON, there is problem with the device.

The optical interface LOF indicator (red) turns ON.

Loss of frame alarm of the receiving signal at the optical interface occurs. Optical signal has been received, but the optical power may be around the critical receiving sensitivity. Please measure the receiving optical power and make sure that the TX interface of the optical interface of the remote device has been well connected.

Optical interface indicator ERR (red) turns ON.

The bit error rate of the receiving signal at the optical interface exceeds 1E-3 or 1E-6. The E-6 alarm may occur when the device is just electrified and the ERR indicator may turn ON. This is a normal phenomenon and will last at most 10 seconds before the ERR indicator turns OFF. If the E-6 alarm occurs during the normal operation of the device, please check whether the optical interface is well connected and please measure the optical power.
