• Check the data path for both Ethernet forwarding and Fibre Channel traffic. The Verification that the
Data Path is Ready section in the Cisco UCS Manager Firmware Management Guide provides the steps
to verify the data path.
Procedure
Step 1 Mount the replacement fabric interconnect into either the same rack or an adjacent rack.
Step 2 Using Cisco UCS Manager, verify the state (subordinate or active) of the fabric interconnects.
Step 3 Back up all software configuration information, including state and system configuration.
Step 4 Follow the Fabric Evacuation procedure on the subordinate fabric interconnect to ensure there is no data traffic
impact during the upgrade.
Step 5 Enter the unconfigure all server ports command to remove the configuration from the server ports in the
subordinate fabric interconnect. This steps removes the configuration from the ports that connect to the IOM
and FEXes.
Step 6 Power down the subordinate fabric interconnect by unplugging it from the power source.
Step 7 Disconnect the cables from the IOM or FEXes to the subordinate fabric interconnect ports in slot 1 on the
Cisco UCS 6248 UP fabric interconnect.
Step 8 Connect the cables from the IOM to the corresponding ports on the Cisco UCS 6296 UP fabric interconnect.
Step 9 Disconnect the L1/L2, M1 management, and console cables on the Cisco UCS 6248 UP fabric interconnect.
Step 10 Connect the M1 management and console cables on the Cisco UCS 6296 UP fabric interconnect.
Step 11 Connect the L1/L2 cables that were disconnected to the Cisco UCS 6296 UP fabric interconnect.
Step 12 Connect the power cable to the Cisco UCS 6296 UP fabric interconnect. It will automatically boot and run
POST tests.
Step 13 Connect the cables into the corresponding ports on slot 1 of the Cisco UCS 6296 UP fabric interconnect.
Step 14 Enable and configure all uplink ports and verify connectivity to network uplinks.
Step 15 Enable and configure the server ports that were unconfigured in Step 5. The IOM will start Auto Sync, which
will take approximately 15 minutes. Clear any faults related to failover or data path.
Step 16 Perform an HA lead failover.
Step 17 (Optional) If Fibre Channel ports were configured previously, reconfigure them and reboot the Cisco UCS
6296 UP Fabric Interconnect. The SAN and Port Channels section of the Cisco UCS Manager Storage
Management Guide provides detailed configuration steps.
Repacking the Cisco UCS Fabric Interconnect for Return
Shipment
If you need to return the fabric interconnect, remove the chassis from the rack by following the steps in
Removing a Cisco UCS 6248 UP, on page 48 or Removing a Cisco UCS 6296, on page 48, and repack it for
shipment. If possible, use the original packing materials and container to repack the chassis. Contact your
Cisco customer service representative to arrange for return shipment to Cisco.
