Replacement procedure for quad-port NIC

This topic describes the process of replacing the NIC quad port on an HPE server node.

Identifying a quad-port NIC failure (performed by the customer)

Verify if the cables are unplugged or faulty. After removing cable from quad-port NIC node state in the UI shows Unhealthy.

The eth1 network interface state is shown unplugged in the UI. To view the link status, navigate to Infrastructure > Hardware > Network Card in the NetBackup Flex Scale infrastructure UI.

The network status for the public network is shown unhealthy. Navigate to the dashboard page of the UI:

If you encounter these issues, there might be a problem with the cables connection or the quad-port. To isolate the issue, first tighten the cable connections. If you face the same issue, replace the cables and try again. If the issue persists it implies that the port is faulty. Contact Veritas TSE to replace the faulty quad-port NIC.

Note the MAC address of the network interface. After the quad-port NIC is replaced, the MAC address will change:
