Procedure steps
NN10600-175 6.1S2
Install a CP Ethernet cable as part of replacing a control processor (CP) or to
replace a faulty cable.
• If the CP is spared, coordinate with the software network operator to
remove the CP from service if it is still active and to notify you when to
swap the cables. Alarms are generated when communication to a CP is
stopped.
• If the CP is not spared, have the software operator disable the
SwitchoveronFailure attribute as described in the section "Disabling CP
switchover for a CP OAM Ethernet port failure" in NN10600-550 Nortel
Networks Multiservice Switch 7400/15000/20000 Common
Configuration Procedures.
• Route and label cables.
• Follow "Avoiding damage from static electricity" (page 208) to protect
the unit from damage by ESD or from transferring ESD to other
hardware.
1 Refer to the figure "Example of a control processor faceplate" (page 263)
to located the Ethernet connector on the CP faceplate.
2 Unplug the old cable at each end only when the CP is removed from
service in software. Immediately plug in the new cable.
3 Cut the connectors off the end of the old cable. Tugging or pulling on the
older cable can affect the operation of other cables. Unless it can be easily
removed, leave the old cable in position.
