Avoiding damage from static electricity

NN10600-175 6.1S2
To avoid static electricity damage, handle processor cards only when you use
appropriate antistatic protection. Nortel Networks recommends using an
antistatic wrist strap (PEC A0378999), conductive carpet, conductive shoes,
or heel grounders.
If you wear an antistatic wrist strap, attach the cord to a ground. When a
Nortel Networks Multiservice Switch cabinet is properly grounded, you can
use the electrostatic discharge (ESD) jack on the shelf assembly. For ESD
jack locations, see these figures
• "Multiservice Switch 7420 ESD jack location" (page 209)
• "Multiservice Switch 7440 ESD jack location" (page 210)
• "Multiservice Switch 7460 ESD jack location" (page 211)
• "Multiservice Switch 7480 ESD jack location" (page 212)
Nortel Networks provides an antistatic wrist strap with each device. If a
device is installed in a cabinet or rack with another device that has an
antistatic wrist strap attached to it, you do not need to install a second one.
Handle processor cards by the faceplate or stiffener. Do not touch electrical
connections, pins, or soldered surfaces.
