Installation precautions

Before you install any server component, we recommend that you read

the following sections. These sections contain important ESD

precautions along with pre-installation and post-installation

instructions.

ESD precautions

Electrostatic discharge (ESD) can damage the processor, disk drives,

expansion boards, mainboards, memory modules and other server

components. Always observe the following precautions before you

install a server component:

• Do not remove a component from its protective packaging until

you are ready to install it.

• Do not touch the component pins, leads, or circuitry.

• Components with a Printed Circuit Board (PCB) assembly should

always be laid with the assembly-side down.

• Wear a wrist grounding strap and attach it to a metal part of the

server before handling components. If a wrist strap is not

available, maintain contact with the server throughout any

procedure requiring ESD protection.

• Keep the work area free of nonconductive materials, such as

ordinary plastic assembly aids and foam packing.

Pre-installation instructions

Perform the steps below before you open the server or before you

remove or replace any component:

Warning! Failure to properly turn off the server before you start

installing components may cause serious damage. Do not attempt

the procedures described in the following sections unless you are

a qualified service technician.

1 Turn off the system and all the peripherals connected to it.

2 Unplug all cables from the power outlets.

3 Disconnect all telecommunication cables from their ports.

4 Place the system unit on a flat, stable surface.

5 Open the system according to the instructions on page 36.
