Replace a power supply unit (PSU)
Lenovo ThinkAgile HX Series appliances use two power supply units. Those power supplies are redundant
when using 208 - 230V input power, allowing one power supply to meet the needs of the node. Losing one
power supply may not impact node operation, however, replace a failed power supply unit as soon as possible
to restore redundancy.
A failed power supply unit is indicated by:
• Amber warning LED on node front panel is on
• XCC shows a power supply alert
• Nutanix Prism web console shows a power supply alert
• If using VMware ESXi, the vSphere client Hardware Status tab shows a power supply alert.
