Removing and Replacing Modules

This procedure describes how to remove and replace the internal modules of the node. All field-replaceable
modules can be removed and replaced without removing power from the node.
Field-replaceable modules include:
• Forward optical receiver modules
• Reverse optical transmitter modules
• Status monitor/local control module
• Forward configuration module
• Reverse configuration module
• Equalizers
• Node signal directors
• Power supply modules
• RF amplifier assembly
• RPD Module
Caution
Removing power from the node will interrupt customer service. Removing any module, except for the status
monitor/local control module, will interrupt customer service unless that module has a redundant backup.

Module Replacement Procedure

Follow this procedure to remove and replace an optical receiver, optical transmitter, optical amplifier, optical
switch, status monitor/local control module, or power supply module.
1. Open the housing. See
2. Carefully tag and remove any optical fibers from RPD, receiver or transmitter module.
Warning
Laser light hazard. Never look into the end of an optical fiber or connector. Failure to observe this warning
can result in eye damage or blindness.
3. Loosen the screws securing the module.
4. Lift the module straight up out of the housing to unplug it.
