Replacing Supervisor Modules (SUP3) on a Cisco 7000 Nexus Device

[cesarausan]

This is my first time using the Cisco community forums.

I have reviewed the following Cisco white paper:

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/high_availability/configuration/guide/b_Cisco_Nexus_7000_Series_NX-OS_High_Availability_and_Redundancy_Guide/b_Cisco_Nexus_7000_Series_NX-OS_High_Availability_and_Redundancy_Guide_cha...

But I can't find answer to the following question:

When the standby sup is replaced. will the new standby sup receive the same NXOS revision as the active sup?

Thanks,

Hi,

According to the link you posted, the new standby sup will receive the same version as the active sup.

	Command or Action	Purpose
Step 1	switch # system switchover	Initiates a manual switchover to the standby supervisor. Note    Wait until the switchover completes and the standby supervisor becomes active.
Step 2	switch# out-of-service slot-number	Powers down the supervisor module you are replacing.
Step 3	Remove the supervisor and insert the replacement.	The new supervisor will automatically sync up the image and configuration from the currently active supervisor.
