Avoiding electrostatic discharge (ESD)
damage
The cover and filler panels installed on your equipment protect the
electronic circuits inside the equipment from electrostatic discharge
(ESD) damage. However, when you remove these covers and filler
panels to replace or install subassemblies, you can inadvertently
damage the sensitive electronic circuits in the equipment by simply
touching them. Electrostatic charge that has accumulated on your
body discharges through the circuits. If the air in the work area is
very dry, running a humidifier in the work area will help decrease
the risk of ESD damage. You must follow the procedures below to
prevent damage to the equipment.
CAUTION:
Read and understand the following instructions before you remove
cover(s) or panel(s) from the equipment.
D
Provide enough room to work on the equipment. Clear the work site
of any unnecessary materials or materials that naturally build up
electrostatic charge, such as foam packaging, foam cups, cellophane
wrappers, and similar materials.
D
Do not remove replacement or upgrade subassemblies from their
antistatic packaging until the exact moment that you are ready to
install them.
D
Gather the tools, manuals, an ESD kit, and all other materials you
will need before you remove covers and panels from the equipment.
Procedures for removing subassemblies usually list required
materials at the beginning. After you remove a cover or panel, you
should avoid moving away from the work site; otherwise, you may
build up an electrostatic charge.
D
Use an ESD kit when handling circuit boards or when touching the
electronic circuits inside the equipment. If you don’t have an ESD
kit, you can order one from Data General. If an emergency arises
and an ESD kit is not available, follow the procedures in the
“Emergency Procedures (without an ESD kit)” section.
D
Replace the cover(s) or panel(s) on the equipment as soon as
possible so that the electronic circuits are protected.
D
If the equipment has an opening for an optional device (such as a
mass–storage drive), and the device is not installed, make sure a
filler panel is installed in the opening before connecting the
equipment to the ac power outlet.
