Description
CAUTION: When correcting a power supply mismatch, replace
only the power supply with the flashing indicator. Swapping
the other 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 with the exception of Titanium power supplies,
which support only 220 V. When two identical power supplies
receive different input voltages, they can output different
wattages, and trigger a mismatch.
