LED Status

The Supervisor Module status LED blinks twice with one second gap until the grace period is over.

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.

Note

Warning

Illustrations are for representational purposes only.

The below figure describes the components used in the Supervisor installation procedure.

When you enable this feature, do not remove the module during the 15-second grace period. Remove the

Supervisor Module only in either of the following two ways:

• Allow the Supervisor Module to shut down after the 15-second grace period, then remove the Supervisor

Module.

• Close the ejector lever within the 15-second grace period, then remove the Supervisor Module gracefully

(shutdown the Supervisor Module first) or ungracefully.

HA/SSO is not supported in this release. The hardware is capable, but the software will be enabled in a future

release. The Supervisor module in slot 28 must be in the loader prompt or removed physically.

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.

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when

servicing.
