Overview of Supervisor Modules
The switch has one or two supervisor modules of the following types:
• Supervisor 2 Enhanced (N77-SUP2E)
• Supervisor 3 Enhanced (N77-SUP3E)
You can use only one type of supervisor module in a switch.
Note
When a switch has two supervisors, one supervisor is automatically active while the other is in standby mode.
If the active supervisor goes down or is disconnected for replacement, the standby supervisor automatically
becomes active. If you need to replace one of two installed supervisor modules with another module, you can
do this without interrupting operations—the supervisor that you are not replacing becomes the active supervisor
and retains the kickstart configuration while you replace the other supervisor.
If the switch has just one supervisor, you can install the new supervisor in the open supervisor slot during
operations and make that supervisor active after the installation.
Supervisor modules are automatically powered up and started with the switch.
To understand the terms used for the supervisors, see the following table.
