CAUTION: When correcting a power supply mismatch, replace only the power supply with
the flashing indicator. Swapping the opposite power supply 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 power down
the system.
CAUTION: AC power supplies support both 220 V and 110 V input voltages. When two
identical power supplies receive different input voltages, they can output different
wattages, and trigger a mismatch.
CAUTION: If two power supplies are used, they must be of the same type and have the
same maximum output power.
