Nortel 7400 Hardware Installation page 255

Procedure steps
1 Unlock the latches on the CP. See the figure "Locking and unlocking
processor card latches" (page 324).
2 Hold the CP in front of the shelf assembly so that:
• you do not touch the copper-colored metal EMI gasket at the edge of
the card
• its faceplate faces you
• it is parallel to the slot (vertically or horizontally)
• its bottom is positioned next to the cooling unit when the shelf
assembly is mounted vertically or horizontally
3 Carefully slide the processor card into the appropriate slot. If this is the
first CP, then it goes into slot 0.
If this is the second CP, then it goes into the slot at the opposite end of the
shelf. For example, slot 7 in a Multiservice Switch 7460, or slot 15 in a
Multiservice Switch 7480.
4 Pull open the top and bottom latches of the processor card and slide the
card into the slot until the locking latches begin to close.
5 Close the latches to seat the processor card connectors in the backplane
connectors and apply some additional pressure to the faceplate to ensure
that the processor card is fully inserted in the shelf.
6 Lock the latches as shown the figure "Locking and unlocking processor
card latches" (page 324).
7 If synchronization does not automatically begin, manually synchronize the
inserted CP with the active CP. See the section on disk synchronization in
NN10600-550 Nortel Networks Multiservice Switch 7400/15000/20000
Common Configuration Procedures.
8 Monitor the status of the processor card by observing the status LED as
it lights throughout the initialization sequence. It can take several minutes
for a new control processor to be synchronized. See "Processor card LED
status display" (page 326).
9 Connect any CP cables as necessary. See "Connecting a local operator
terminal to a Multiservice Switch 7400" (page 221); "Installing a CP
Ethernet cable" (page 262); or "Installing CP cables for BITS" (page 329).
