Installing an Ethernet cable
Install an Ethernet cable as part of replacing a CP, or to replace a faulty cable.
Prerequisites
• 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 “Changing the
switchover behavior of the OAM Ethernet port” in 241-5701-600
Passport 7400, 15000, 20000 Configuration Guide.
• Route and label cables.
Procedure steps
1 Refer to the figure “Example of a control processor faceplate” (page 260)
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.
