Verification command: 

3. Reloading standby supervisor which is in module 6 :

                Note: after completion of ROMMON image upgrade please reload the supervisor engine (not switchover)

Wait until SSO and redundancy mode to come up and working properly:
Redundancy verification commands:

4. Start upgrading module 5 (active sup) ROMMON:

Verification before the upgrade ROMMON supervisor on module 5:

5. Upgrade of active supervisor which is in module 5:

Note: first we need to switchover active sup which is in slot 5,  after becoming active sup as  standby then we will start upgrading.
 Redundancy switchover command:

Wait until SSO and redundancy mode to come up and working properly:

6. ROMMON upgrade on Module 5:

SP upgrade command

 RP upgrade command

7. Reload of standby Supervisor which is in module 5:

 Note: after completion of ROMMON image upgrade please reload the supervisor engine (no switchover) 

8. Once module 5 come up we will verify that ROMMON upgrade is done successfully? 

Note: Once standby supervisor come up we will switchover module 6 active to standby in order to keep active module 5 and standby module 6 but this is not necessary just for consistency.

9. Roll back setups

a)  Connect to the supervisor using console connection.
b) Check if we have some response from console.
c)  If yes most likely supervisor  is in ROMMON mode .
d) We should try to boot IOS from ROMMON (using “boot [path to IOS]” command).
e) If there will be no response from console try to reboot it one more time by powering it off and on.
f) If after power cycle there will be no response from console it would mean that supervisor has failed and has to be replaced.
