Avoiding Electrostatic Discharge
Some of the sensitive components inside the base unit can be damaged by static electricity. To
minimize this possibility, take the following precautions when working with the internal components of
the system.
u
To maintain ground, do not unplug the power cord from the base unit, AC outlet, or UPS.
u
Touch the bare metal of the base unit to discharge any accumulated electrostatic charge.
u
Do not service the system on surfaces known to have high electrostatic buildup, such as rugs and
carpets. Work on a static-safe surface instead.
u
Handle all printed circuit boards as little as possible and by the edges only. Leave new parts in
their protective packaging until you install them.
u
After opening the base unit, attach a disposable or reusable antistatic wrist strap as described in the
next section.
NOTE There is no increased risk of electrical shock when using an antistatic wrist strap. If the wrist strap
does not snugly contact bare skin, static protection will not be effective.
To attach a disposable antistatic wrist strap:
1. Remove the wrist strap from the envelope.
2. Unfold the wrist strap and wrap the exposed adhesive side firmly around your bare wrist.
3. Peel the liner from the wrist strap copper foil. Attach the adhesive side of the copper foil to a bare
flat metal surface (electrical ground) inside the base unit.
NOTE After using a disposable wrist strap once, you cannot use it again.
