Use the following procedure to prevent static damage whenever you are accessing
any of the internal components of the system.

Before You Begin

Complete this task if you are working with a component that is not hot-pluggable:
"How to Power Off the System" on page 5
■
You must have the following items:
Antistatic wrist or foot strap
■
Antistatic mat (or the equivalent)
■

What to Do

Caution – Printed circuit boards and hard disk drives contain electronic
components that are extremely sensitive to static electricity. Ordinary amounts of
static from your clothes or the work environment can destroy components.
Do not touch the components or any metal parts without taking proper antistatic
precautions.
1. Disconnect the AC power cord from the wall power outlet only when performing
the following procedures:
Removing and installing the system controller card
■
Removing and installing the I/O board
■
Removing and installing the power distribution board
■
The AC power cord provides a discharge path for static electricity, so it should
remain plugged in except when you are servicing the parts noted above.
