Power Supply Indicators
Each AC power supply has an illuminated translucent handle that serves as an indicator to show whether power is
present or whether a power fault has occurred. The AC power supplies must be connected to a Power Distribution Unit
(PDU) or to an electrical outlet.

AC power supply status indicator/handle
The power supply indicators provide the following information:
Power Indicator
Condition
Pattern
Not lit
Power is not connected.
Green
In standby mode, the handle lights green indicating that a valid power source is connected to
the power supply and that the power supply is operational.
Flashing amber

CAUTION: When correcting a power supply mismatch, replace only the power supply
with the flashing 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 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. When two
identical power supplies receive different input voltages, they can output different
wattages, and trigger a mismatch.
CAUTION: All power supplies used must be of the same type and have the same
maximum output power.
