Step 5. Align the mounting stud on the chassis with the hole in the LOM-adapter air baffle. Then, pinch the
tab
1 and lower the LOM-adapter air baffle onto the LOM adapter.
After installing the LOM adapter:
1. Replace the top cover.
2. Install the node back into the rack and reconnect all cables.
3. Power on the node.
4. Exit maintenance mode.
5. Verify that the NIC is replaced successfully:
• The amber warning light on the node front panel is off.
• All network ports are fully functional.
PCIe adapter replacement
Use this information to remove and install a PCIe adapter.
ThinkAgile HX 1521-R, HX3521-G, HX5521, HX5521-C, HX7521 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 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
