4 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. Disconnect the AC power cord from the wall power outlet only if you will be
handling the power distribution board.
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 cord is when you service the power
distribution board.
2. Use an antistatic mat or similar surface.
When performing any option installation or service procedure, place
static-sensitive parts, such as boards, cards, and disk drives, on an antistatic
surface. The following items can be used as an antistatic surface:
4 The bag used to wrap a Sun
4 The shipping container used to package a Sun replacement part
4 Sun electrostatic discharge (ESD) mat, PN 250-1088 (available through your
Sun sales representatives)
4 Disposable ESD mat, shipped with replacement parts or options
3. Use an antistatic wrist strap.
Attach the appropriate end to the system chassis sheet metal, and attach the other
end of the strap to your wrist. Refer to the instructions that come with the strap.
