Replace a network interface card (NIC)
Lenovo ThinkAgile HX Series appliances can support up to eight network ports; two or four 10 GbE ports (up to
2 NICs), and two or four 10 GbE ports on the LOM adapter, connected to the motherboard. A node requires
network connectivity to function as part of a cluster. If one network interface is available, the failure of the other
network interfaces does not cause service interruption.
A failed NIC is indicated by:
•
No LED is illuminated for the network interface
•
Guest VM performance degrades
•
Guest VMs, the Nutanix web console, and nCLI are unavailable
•
VM migration fails with an error message such as:
The migration was cancelled because the amount of changing memory for the VM was
greater than the available network bandwidth

Replace an NIC:
1.
Lenovo ThinkAgile HX Series appliances can contain zero or one LOM NIC, with two or four ports, as well
as up to two PCIe NICs. For nodes with multiple NICs, verify which has failed. Identify the failed NIC by
either checking in the XCC 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 if the cable management arm is not in place, disconnect all. Pull the node chassis
out of the rack.
