Termination Or Sparing Panel Replacement - Nortel Multiservice Switch 7400 Installation & Maintenance

Termination or sparing panel
replacement
Replace a termination or sparing panel for failure or upgrade, to restore or
maintain configured services or redundancy.
Prerequisites to termination or sparing panel replacement
• Some of the procedures in this task are not located in this document.
Ensure that you have access to the required documents.
• There are two types of sparing panels, single and modular. Single sparing
panels are used for sparing most types of FPs. Modular sparing panels are
used for sparing 32-port multi-service access (MSA32) DS1 or E1 FPs,
and 8-port multi-service access (MSA8) DS1 or E1 FPs. When replacing
a single sparing panel, traffic is disrupted for the time it takes to perform
the procedure.
• If you replace termination or sparing panels in the back of a seismic
cabinet containing Nortel Multiservice Switch 7480s, leave some rack
space between the termination panels for each device. This space aids
airflow through the cabinet and provides space for cables.
• Before you start, ensure that each cable connected to the panel is labeled
to indicate where it connects to the faceplate.
• If cables are connected incorrectly, the device raises one or more alarms.
