CAUTION
Risk of electrostatic damage
When handling processor cards, wear a grounded antistatic wrist
strap so that you do not damage electronic parts. For more
information, see Avoiding damage from static electricity (page
CAUTION
Service loss on active ports
Unspared FPs, including FPs configured with intra-card APS (port-
to-port sparing on a single FP), will experience a loss of service on
any active ports for the time it takes to replace the FP.
CAUTION
Risk of equipment damage from software
An incompatible software load can damage an FP beyond a field
repair. Ensure that the software running on the device meets the
minimum software requirement for an FP. For more information, see
NN10600-551 Nortel Multiservice Switch 7400/15000/20000 FP
Configuration Reference.
CAUTION
Risk of service loss
Whenever you install an FP that uses a control cable in a sparing
configuration, you must always insert the FP into a slot on the shelf
before you connect the control cable. If you connect the control cable
between the FP and the termination or sparing panel before you
insert the FP in the shelf, you can disrupt service to the other FPs in
the sparing configuration.
