Removing And Replacing Modules - Cisco GS7000 Installation And Operation Manual

Removing and Replacing Modules

Overview
This procedure describes how to remove and replace the internal modules of the 1.2
GHz GS7000 Node. All field-replaceable modules can be removed and replaced
without removing power from the 1.2 GHz GS7000 Node.
Field-replaceable modules include:

Forward optical receiver modules

Reverse optical transmitter modules

Optical amplifier modules

Optical switch modules

Status monitor/local control module

Forward configuration module

Reverse configuration module

Equalizers

Node signal directors

Power supply modules

RF amplifier assembly
CAUTION:
Removing power from the 1.2 GHz GS7000 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 Opening and Closing the Housing (on page 122).
2 Carefully tag and remove any optical fibers from a receiver or transmitter
module.
