Installing or Replacing a Supervisor Module
You can install or replace a supervisor module during switch operations so long as there is another supervisor
module installed and operating on the switch. If you eject the active supervisor from its slot in a chassis with
two supervisor modules, operations automatically switch over to the standby supervisor module. If you need
to replace a supervisor in a chassis with just one supervisor, you can install the new supervisor in the open
supervisor slot, make the new supervisor active, and remove the other supervisor module.
If you remove a supervisor module without replacing it, you must fill the slot with a blank filler plate to
maintain the designed airflow for the chassis.
Note
Before you begin
The system will shut down when you remove the single supervisor module in the Cisco Nexus 7702 chassis.
Caution
• You must follow ESD protocols, including the following:
• You must wear a grounded ESD wristband (or other personal grounding device) whenever you
handle the electronic modules outside the grounded chassis.
• You must carry electronic modules by only their covered edges or handles. Do not touch their
electronic components.
• Whenever a module is outside a grounded chassis, place it flat on an antistatic surface or in an
antistatic bag. Never lean the module on anything nor place anything else on top of the module nor
lean anything on the module.
• Verify that the chassis is grounded.
• Verify that you have the following tools and equipment:
• ESD wrist strap (or other personal grounding device)
• Number 1 Phillips torque screwdriver
Manual torque screwdrivers are recommended. Be sure to never exceed the recommended torque
setting for the screw that you are working with.
• Replacement supervisor module
• Supervisor 2E (N77-SUP2E=)
Step 1
If you need to remove a supervisor module to open the slot for a new module, follow these steps (if you already have an
open slot, go to the next step):
If the slot that you need to open has a blank filler plate, remove the plate by unscrewing its captive screw and
pulling on the handle attached to the plate to remove the plate, and go to Step 3).
