Overview of Supervisor Modules

The switch has one or two supervisor modules of the following types:
• Supervisor A (N9K-SUP-A) modules with four cores, 4 executable threads, 16 GB of memory, and 64
• Supervisor A+ (N9K-SUP-A+) with four cores, 8 executable threads, 1.8 GHz, 16 GB of memory, and
• Supervisor B (N9K-SUP-B) with six cores, 12 executable threads, 2.2 GHz, 24 GB of memory, and 256
• Supervisor B+ (N9K-SUP-B+) with six cores, 12 executable threads, 1.9 GHz, 32 GB of memory, and
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 so 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.
