CAUTION: When correcting a PSU mismatch, replace only the PSU with the
blinking indicator. Swapping the PSU to make a matched pair can result in an
error condition and unexpected system shutdown. To change from a High Output
configuration to a Low Output configuration or vice versa, you must turn off the
system.
CAUTION: If two PSUs are used, they must be of the same type and have the same
maximum output power.
CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.
