CAUTION: When correcting a power supply unit mismatch,

 

 

replace only the power supply unit with the flashing indicator.

 

 

Swapping the opposite power supply unit 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.

 

 

CAUTION: If two power supplies are used, they must be of the

 

 

same type and have the same maximum output power.

 

 

CAUTION: Combining AC and DC power supplies is not

 

 

supported and triggers a mismatch.
