Electrostatic Discharge (ESD) Considerations 
!
CAUTION:
Industry experience has shown that all integrated circuit packs can be 
damaged by static electricity that builds up on work surfaces and personnel. 
The static charges are produced by various charging effects of movement 
and contact with other objects. Dry air allows greater static charges to 
accumulate. Higher potentials are measured in areas with low relative 
humidity, but potentials high enough to cause damage can occur anywhere. 
The following precautions should be observed when handling circuit packs in 
order to prevent damage by electrostatic discharge:
■
Assume all circuit packs contain solid state electronic components that can 
be damaged by ESD. Use only Lucent manufactured 
UL
*
recognized circuit 
packs in this system. 
■
When handling circuit packs (storing, inserting, removing, etc.) or when 
working on the backplane, always wear a grounded wrist strap or wear a 
heel strap and stand on a grounded, static-dissipating floor mat. If a static-
dissipating floor mat is used, be sure that it is clean.
