ThinkAgile HX2320 Appliance and HX2321 Certified Node appliances can support up to eight network ports;
two or four 10 GbE ports (up to two NICs), and two or four 10 GbE ports on the LOM adapter, connected to

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 vSphere Web console, and nCLI are unavailable.
