Replacing the Fabric Interconnect
Procedure
Step 1
Label the ports and the cables that you using so that you can refer to this information later. The cabling and
port numbering should be same for the replacement fabric interconnects.
Step 2
Disconnect all the cable connections, including servers, FEX fabrics, and blade chassis, from the old fabric
interconnects.
Step 3
Power down the fabric interconnects by unplugging it from the power source.
Step 4
Remove the fabric interconnects from the rack. Follow the instructions in
Interconnect From a Rack, on page
Step 5
Install the replacement fabric interconnects into the rack. Follow the instructions in
Interconnect, on page
Step 6
Connect all the cable connections, including servers, FEX fabrics, and blade chassis, from the old fabric
interconnects to the new fabric interconnects.
a) Connect the L1/L2 cables that were disconnected to the replacement fabric interconnects.
b) Connect the data cable according to the labels that you created in Step 2.
c) Connect the power cable to the fabric interconnects, and it will automatically boot and run POST tests.
Step 7
Complete the Basic System Configuration Dialog for the new fabric interconnects, replying to the dialog's
prompts as necessary.
Important
For an example of the Basic System Configuration Dialog, see
Console.
• If there is no explicit upgrade required, the newly replaced fabric interconnects can be upgraded through
IMM after they are claimed by Intersight, but before the RMA workflow is activated.
• If an explicit upgrade is required, you can perform the upgrade through IMM after the fabric interconnects
are claimed by IMM.
Step 8
Complete the Basic System Configuration Dialog for the new fabric interconnect pair.
Important
Step 9
If necessary, upgrade the software bundles so that the fabric interconnects are in sync.
Example:
