PCIe adapter replacement
Use this information to remove and install a PCIe adapter.
ThinkAgile HX1321, and HX3321 Series 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 the system
board. 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 vSphere 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
