Power Indicator
Pattern
Condition
Not lit Power is not connected.
Green The handle/LED indicator lights green indicating that a valid power source is connected to the power supply and
that the power supply is operational.
Flashing amber Indicates a problem with the power supply.
CAUTION: When correcting a power supply mismatch, replace only the power supply with the ashing
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 conguration to a Low Output
conguration 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 dierent
input voltages, they can output dierent 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.
