Warnings

System power on/off: The power button DOES NOT turn off the system

AC power. To remove power from system, you must unplug the AC power

cord from the wall outlet. Make sure the AC power cord is unplugged before

you open the chassis, add, or remove any components.

Hazardous conditions, devices and cables: Hazardous electrical

conditions may be present on power, telephone, and communication cables.

Turn off the server and disconnect the power cord, telecommunications

systems, networks, and modems attached to the server before opening it.

Otherwise, personal injury or equipment damage can result.

Electrostatic discharge (ESD) and ESD protection: ESD can

damage disk drives, boards, and other parts. We recommend that you

perform all procedures in this chapter only at an ESD workstation. If one is

not available, provide some ESD protection by wearing an antistatic wrist

strap attached to chassis groundany unpainted metal surfaceon your

server when handling parts.

ESD and handling boards: Always handle boards carefully. They can be

extremely sensitive to ESD. Hold boards only by their edges. After removing

a board from its protective wrapper or from the server, place the board

component side up on a grounded, static free surface. Use a conductive foam

pad if available but not the board wrapper. Do not slide board over any

surface.

Installing or removing jumpers: A jumper is a small plastic encased

conductor that slips over two jumper pins. Some jumpers have a small tab on

top that you can grip with your fingertips or with a pair of fine needle nosed

pliers. If your jumpers do not have such a tab, take care when using needle

nosed pliers to remove or install a jumper; grip the narrow sides of the

jumper with the pliers, never the wide sides. Gripping the wide sides can

damage the contacts inside the jumper, causing intermittent problems with

the function controlled by that jumper. Take care to grip with, but not

squeeze, the pliers or other tool you use to remove a jumper, or you may

bend or break the stake pins on the board.
