SIOC Management in Cisco UCS Manager
You can manage and monitor all System Input/Output Controllers (SIOC) in a Cisco UCS domain through Cisco UCS Manager.
SIOC Removal or Replacement
You can remove or replace an SIOC from a chassis. Removal or replacement of an SIOC is a service-affecting operation, which requires you to power down the entire chassis.
Guidelines for SIOC Removal
-
To remove the active SIOC, or both SIOCs, shut down and remove power from the entire chassis. You must disconnect all power cords to completely remove power.
-
Removal of SIOCs from a chassis results in the entire chassis being disconnected from Cisco UCS Manager.
SIOC Removal

-

SIOC Replacement
Do the following to remove an SIOC from the system and replace it with another SIOC:
-
Shut down and remove power from the entire chassis. You must disconnect all power cords to completely remove power.
-
Disconnect the cables connecting the SIOC to the system.
-
Remove the SIOC from the system.
-
Connect the new SIOC to the system.
-
Connect the cables to the SIOC.
-
Connect power cords and then power on the system.
-
Acknowledge the new SIOC.
The server connected to the replaced SIOC is rediscovered.
Note
If the firmware of the replaced SIOC is not the same version as the peer SIOC, then it is recommended to update the firmware of the replaced SIOC by re-triggering chassis profile association.
