Safety
............................................................................................................................................................................................................................................................
In order to prevent damage by electrostatic discharge the following precautions should be
observed when handling circuit packs:
Assume all circuit packs contain solid state electronic components that can be
•
damaged by ESD.
When handling circuit packs (storing, inserting, removing, etc.) or when working on
•
the backplane, always wear a grounded wrist strap such as the one shown in
Figure 1-1, "Static control wrist strap" (p. 5)
grounded, static dissipating floor mat. If a static dissipating floor mat is used, be sure
that it is clean to ensure a good discharge path.
Handle all circuit packs by the faceplate or latch and by the top and bottom outermost
•
edges. Never touch the components, conductors, or connector pins.
Observe warning labels on bags and cartons. Whenever possible, do not remove circuit
•
packs from antistatic packaging until ready to insert them into slots.
If possible, open all circuit packs at a static safe work position, using properly
•
grounded wrist straps and static dissipating table mats. If a static dissipating floor mat
is used, be sure that it is clean to ensure a good discharge path.
Always store and transport circuit packs in static safe packaging. Shielding is not
•
required unless specified.
Keep all static generating materials such as food wrappers, plastics, and styrofoam
•
containers away from all circuit packs. Upon removal from bay, immediately put
circuit packs into static safe packages.
Whenever possible, maintain relative humidity above 20 percent.
•
To reduce the possibility of ESD damage, assemblies are equipped with grounding jacks
to enable personnel to ground themselves using wrist straps

for connection of wrist straps are located at the lower right-hand corner of each assembly
and are labeled. When grounding jacks are not provided, an alligator clip adapter enables
connection to bay frame ground.
