Figure 34. Chassis fan
To replace a chassis fan, perform the following steps:
1. It is possible to replace the chassis fan while the system is powered on providing that the cable
management arm is in place by pulling the node chassis out of the rack.
2. Remove the top cover as described in “Removing the top cover” on page 116.
3. Replace the chassis fan with the error LED on as described in “Replacing a hot-swap fan” on page 138.
4. Replace the top cover as described in “Replacing the top cover” on page 118.
5. Push node chassis back into the rack.
6. Verify that the chassis fan has been successfully replaced by checking the following:
• Error LED for the replaced fan is off.
• Orange warning light on the node front panel is extinguished.
• No error shown in Lenovo XClarity Administrator.
• No error shown in Prism.
Replacing a network interface card (NIC)
The Lenovo Converged HX Series appliances can support up to eight network ports: two or four 10 GbE
ports (up to 2 NICs) and four 1 GbE ports on 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 but may cause service degradation.
The indications of a failed NIC include:
• 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 following:
The migration was cancelled because the amount of changing memory for the VM was greater than the available network bandwidth
