10.2. Replace Power Supply Unit
XCubeNAS comes with two redundant Power Supply Units (PSU) that can be hot swapped it
when the PSU is not functioning. If a PSU or its fan failed to function, you can check the PSU
status in two ways:
1.
On PSU: the PSU LED will turn to color
2.
In QSM: Please go to Monitor app Hardware. The PSU status will show "Error" if
failed. You can also check the status by clicking Dashboard on the top right corner on
the desktop. The System Status will also display "Error" and its message, "PSU(No.) is
not functioning".
