Removing An Fp - Nortel 7400 Hardware Installation

Removing an FP

Prerequisites
Multiservice Switch 7400 Hardware Installation, Maintenance, and Upgrade 6.1S2
Remove a function processor (FP) to replace it or decommission the slot.
CAUTION
Risk of damage by electrostatic discharge (ESD)
When you handle processor cards, wear a grounded
antistatic wrist strap or equivalent to protect electronic
parts. For more information, see "Avoiding damage from
static electricity" (page 208).
CAUTION
Risk of service loss by signal noise
Inserting or removing a processor card from a shelf can
cause noise on the backplane that causes loss of service.
Therefore, minimize the time you take to insert or
remove a processor card. Do not let a processor card sit
in the shelf with a partial connection to the backplane.
CAUTION
Risk of service loss
Before seating or unseating an FP in a sparing
configuration, ensure that all the cables on the faceplate
are disconnected. Seating a cabled FP can cause a traffic
loss on the other FPs in the sparing configuration.
• Remove an FP only after a software operator has removed it from service.
• Ensure that you are removing the appropriate FP. The LED of the FP you
are removing must not be solid green. For more information, see the table
"Processor card LED status display" (page 326).
