Chapter 8 Removal and Installation Procedures
Replacing a Supervisor Module
Replacing a Supervisor Module
The Cisco Nexus 7000 Series devices can be configured with one or two supervisor modules. If the
system has two supervisor modules, you can replace one of the supervisors while the other one manages
system operations. If the system has only one supervisor, you must bring the system down to replace the
supervisor module because the supervisor module is required for managing operations.
For instructions on replacing these supervisor modules, see the following sections:
Required Tools, page 8-4
Replacing One of Two Supervisor Modules During System Operations, page 8-4
Replacing a Supervisor Module in a Single-Supervisor System, page 8-7
Required Tools
You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on
the supervisor module.
Replacing One of Two Supervisor Modules During System Operations
During operations, one supervisor is active while the other supervisor is in standby mode. You can
replace either of these two supervisors. If you need to replace the active supervisor, it becomes the
standby supervisor as soon as you press its ejector buttons.
Caution If you cannot immediately replace a supervisor, either leave the supervisor in its slot until it can be
replaced or replace it with a blank module so the system airflow is not disrupted. If the system airflow
is disrupted for more than a couple of minutes, the system could overheat and shut down.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
Statement 1034
Caution Handle each supervisor or I/O module carefully using an ESD wrist strap, holding the module only on
its carrier edges without touching any electronic circuitry, and placing the module on antistatic mats or
antistatic foam when it is not installed in the Cisco Nexus 7000 Series chassis.
To replace a supervisor module, follow these steps:
Step 1 Place an antistatic mat or antistatic foam where you can place the new and old supervisor modules.
Step 2 Place the replacement supervisor module on the antistatic mat or antistatic foam.
Step 3 Loosen the two captive screws identified in View A of Figure 8-1.
