Removing an FP cable
Remove an FP cable to replace it due to a fault, an upgrade, or a change (re-
deployment).
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• Unless prefabricated cable assemblies are available from Nortel
Networks, you must provide a custom-made replacement cable
assembly. Cable specifications are located in 241-1501-200 Passport
15000, 20000 Hardware Description.
• When you are replacing a cable from an FP that uses small-form
pluggable (SFP) optical modules between the cable and the FP faceplate,
leave the SFP module inserted in the faceplate.
Procedure steps
1 Locate the cable to be removed.
2 Unplug the cable connector at the faceplate of the FP. While unplugging,
pull straight away from the angle of the receptacle on the faceplate. If the
cable connection includes an inline attenuator, re-use it. Fiber optic cards
have cable hoods that must be propped open while disengaging
connectors. Different types of connectors have various disengaging
mechanisms, as follows.
CAUTION
Risk of service loss
Ensure that the cable being removed is not carrying traffic
before you remove it.
CAUTION
Risk of equipment damage
To prevent equipment damage, disconnect the cables
attached to the ports of an FP before you disconnect the
control cable that connects the FP to a termination panel.
