Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

• Locate the emergency power-OFF switch in the room in which you are working. Then, if an

electrical accident occurs, you can quickly shut the power OFF.

Safety Recommendations

Warning Read the installation instructions before you connect the system to its power source.

Warning Ultimate disposal of this product should be handled according to all national laws and

regulations.

Warning Only trained and qualified personnel should be allowed to install or replace this

equipment.

Warning To ensure your safety and the safety of others, be sure the power is OFF and the power

cord is unplugged before working on the router.

• Disconnect all power before doing the following:

— Installing or removing a chassis
— Working near power supplies

Warning Beforeworkingon equipment thatis connected topowerlines, remove jewelry (including

rings, necklaces, and watches).Metal objects will heat upwhen connected to power and ground and
can cause serious burns or weld the metal object to the terminals.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.

Required Tools and Equipment

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power

extension cables, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

— Use caution; do not become a victim yourself.
— Turn OFF power to the system.
— Ifpossible, send anotherperson to getmedical aid. Otherwise,determine the conditionof the

victim and then call for help.

— Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge(ESD) can damage equipment and impair electrical circuitry. It occurs when
electronic printed circuit cards are improperly handled and can result in complete or intermittent
failures.Always follow ESD preventionprocedureswhen removingandreplacing cards. Ensure that
the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring
that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to
safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and
shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground
yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be

between 1 and 10 megohms (Mohm).

Required Tools and Equipment

This kit includes the following items:

• An AC or DC power supply

• Power ratings labels

To install the power supply, you will also need the following tools and equipment (which are not
included):

• Cisco AS5200 access server

• Medium-size Phillips screwdriver

• ESD-preventive wrist strap

• Tie-wraps (optional)

• Antistatic bag (optional)

Removing the Chassis Cover

Warning Do not touch the power supply when the power cord is connected. For systems with a

power switch, line voltages are present within the power supply even when the power switch is off
and the power cord is connected. For systems without a power switch, line voltages are present
within the power supply when the power cord is connected.

Take these steps:

Step 1 Power OFF the access server.

Before working on a chassis or working near powersupplies, unplug the power cord on AC units;

disconnect the power at the circuit breaker on DC units.

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact

with telephone-network voltages.

Warning Do not work on the system or connect or disconnect cables during periods of lightning

activity.

Removing the Chassis Cover

Step 2 Remove all cables from the rear panel of the access server.
Step 3 Place the access server so that the front panel is facing you.
Step 4 Remove the three screws located on the top cover of the chassis.
