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 device or in the text. It indicates potential safetyhazards 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 withthe 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 opticcable 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 device 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, maintenanceor repairs to this product. No installation, adjustment, maintenance or repairs should be performed by

either the operator or the user.

Before operating modules in the electricity conditions, please be noticed that optical modules shall be connected with optical fiber wires or shield with optical module cover for fear that laser light

harms to operator’s eyes.

Handling Energized Products

General Safety PracticesDo 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 ora fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous,


6/19

energy hazards may still exist.Before working on device 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 earthlug 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 device should be mounted only in earthed racks

and cabinets.Always make the ground connection first and disconnect it last. Do not connect telecommunicationcables to ungrounded device. Make sure that all other cables are disconnected before disconnecting

the ground.

Connection of AC MainsMake 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 device and then to the wall socket. If a power switch is

provided in the device, 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 isinstalled in the building installation.

Connection of DC Mains

Unless otherwise specified in the manual, the DC input to the device is floating in reference to theground. 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 toqualified 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. Locatethe circuit breaker of the panel board that services the device 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 inthe 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 properelectrostatic 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 device end of your antistatic strap leash isconnected to the ESD connection sockets on the front of the chassis or to a bare metal surface on thechassis. 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 causecomponent damage.

• Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in astatic shielding bag. If you are returning the item to the factory, immediately place it in a staticshielding bag.

• Handle Modules by the metal card carrier edges only; Avoid touching the board or any connector

pins.
