Preparing a Fabric Interconnect for Removal

Removing a subordinate (standby) fabric interconnect is non-disruptive in a redundant, high-availability Cisco
UCS configuration. Removing a primary (active) fabric interconnect will cause the standby fabric interconnect
to become active with minimal or no disruption.
When powering down and removing clustered fabric interconnects, remove the subordinate fabric interconnect
first, and then remove the primary fabric interconnect.
Caution Be aware that if you remove both the primary and subordinate fabric interconnects, or the single fabric
interconnect from a standalone system, you are shutting down the entire Cisco UCS domain.
Procedure
Step 1 Use Cisco UCS Manager to perform the following tasks:
a) Back up your Cisco UCS Manager configuration.
b) Shut down the OS on all servers in the Cisco UCS domain.
c) Disable the Smart Call Home feature in the Cisco UCS domain.
d) Decommission every attached chassis in the Cisco UCS domain.
For details, see the Configuration Guide for the version of Cisco UCS Manager that you are using. The
configuration guides are available at this URL:
servers-unified-computing/ucs-manager/products-installation-and-configuration-guides-list.html.
Step 2 Power down every attached chassis as described in the
Guide.
