Power Indicator Codes For Redundant Power Supplies

Each 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.

Power Indicator Condition
Pattern
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 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.
