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.
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.
Caution
