Replace a Supervisor Module
The switch supports up to two redundant Supervisor Modules (N9K-C9800-SUP-A). When two Supervisor
Modules are installed in the switch, one acts as an active module and the other as the standby module. When
the active Supervisor Module is removed, the switch automatically makes the standby Supervisor module
active. If the switch has only one Supervisor Module that is installed, a new Supervisor can be installed in
the empty Supervisor slot during operation.

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and
fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the
flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers,
and rear covers are in place.
