WARNING
Static electricity damage
Before removing any cards, put on a wrist strap and connect
it to the wrist strap grounding point on the left side of the
frame supervisory panel (FSP) of the STAR. This protects the
equipment against damage caused by static electricity.
WARNING
Card damage—transport
Take the following precautions to protect circuit cards from
electrical and mechanical damage during transport:
When handling a circuit card not in an electrostatic discharge
(ESD) protective container, stand on a conductive floor mat.
Wear a wrist strap connected, through a 1-megohm resistor,
to a suitably grounded object, such as a metal workbench or a
DMS switch cabinet (Nortel Networks Corporate Standard
5028). Store and transport circuit cards in an ESD protective
container.
