To replace a NIC, perform the following steps:
1. The Lenovo Converged HX Series appliances contain one or two NICs. For nodes with two NICs, ensure
you verify which one has failed. Identify the failed NIC by either checking in XClarity Administrator or
checking the indicator lights on the network ports.
2. Shut down the node by following the hypervisor specific Node Shutdown procedure described in the
Nutanix Hardware Replacement Documentation.
3. Power off the node and disconnect all the cables if the cable management arm is not in place. Pull the
node chassis out of the rack.
4. Remove the top cover as described in "Removing the cover" on page 104.
5. Replace the first (and sometimes only) NIC as described in "Replacing an adapter" on page 126.
6. Replace the top cover as described in "Replacing the cover" on page 105.
7. Push the node chassis back into the rack and reconnect the cables as necessary. Power on the node.
8. Start the node by following the hypervisor specific Node Start procedure described in the Nutanix
Hardware Replacement Documentation.
9. Verify that the NIC has been successfully replaced by checking the following:
• Orange warning light on the node front panel is extinguished.
• All network ports are again fully functional.

Replacing a host bus adapter (HBA)

While a node may be able to self-correct for other adapter card errors, a failed HBA can lead to system
degradation and should be addressed as soon as possible.
