System Board Overview

This chapter describes precautions you should take when handling the system
board. It also shows the layout of the system board and identifies the replaceable
components of the system board.

10.1

Damage Prevention

Caution –

Use an antistatic mat when working with the system board. An antistatic

mat contains the amount of cushioning needed to protect the underside components,
to prevent board flexing, and to provide antistatic protection. Part numbers for
antistatic mats from Sun Microsystems are listed in Chapter 12 “.

10.2

Handling System Boards and
Assemblies

Caution –

The system chassis power switch must be set to Standby, and the AC

power cord must remain plugged in to ensure a proper ground.
