4.7.5 Replacing a Failed RoCE Network Fabric Switch

This procedure describes how to replace a failed RoCE Network Fabric switch.

This procedure depends on having a backup of the configuration for the failed switch.

1. Power off both power supplies on the switch by removing the power plugs.
2. Verify each cable is labeled, and then disconnect each cable from the switch.

   All RoCE Network Fabric cables should have labels at both ends indicating their locations. If there are any cables that do not have labels, then add a label before disconnecting the cable.

   You will use these labels to cable the replacement switch.

3. Remove the switch from the rack.
   1. Extend the rack cabinet's anti-tilt bar.
   2. Attach an antistatic wrist strap.
   3. Remove the switch from the rack.
4. Install the new switch in the rack.
   After you have placed the new switch in the correct position in the rack, if there is no further equipment being serviced in the rack, then you can retract the anti-tilt bar on the rack cabinet.
5. Power on the switch by plugging in the power plugs.
6. Restore the switch settings using the backup, as described in Restoring Settings on a Cisco Nexus 9336C-FX2 RoCE Network Fabric Switch.
7. Connect the cables to the new switch.
   Use the labels on each cable to ensure that you connect each cable to the correct port on the new switch.
8. Complete the steps in Verifying the RoCE Network Fabric Configuration.
