How to Avoid Electrostatic Discharge
Use the following procedure to prevent static damage whenever you are accessing
any of the internal components of the system.
Note – Internal access to the Sun Fire 880 system is restricted to qualified service
personnel only. Installation procedures for internal components are covered in the
Sun Fire 880 Server Service Manual , which is included on the Sun Fire 880
Documentation CD .
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 53
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 themselves or any metal parts without taking proper
antistatic precautions.
1. Make sure that at least one AC power cord remains connected between a power
supply and an AC power outlet.
Note – The AC power cord provides a discharge path for static electricity, so you
generally want to leave it plugged in during installation and repair procedures. The
only time you should unplug the power cords is when you service the power
distribution board or Remote System Control (RSC) card. In each case, make sure
that all power cords are disconnected.
