Condition
CAUTION: When correcting a PSU mismatch, replace only the PSU with the
ashing 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 conguration to a Low Output conguration or vice versa, you must turn
o 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 dierent input voltages, they can output dierent 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.
E Not lit Power is not connected.
