Condition
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.
E Not lit Power is not connected.
