Condition
CAUTION: When correcting a PSU mismatch, replace only the
PSU with the flashing indicator. Swapping the other 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: AC PSUs support both 220 V and 110 V input
voltages with the exception of Titanium PSUs, which support
only 220 V. When two identical PSUs receive different input
voltages, they can output different wattages, and trigger a
mismatch.
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.
Power is not connected.
Power is not connected or PSU is faulty.
A valid power source is connected to the PSU and the PSU is operational.
