Power indicator codes

Each AC power supply unit (PSU) has an illuminated translucent handle and each DC power supply unit (when available) has an LED that serves as an indicator to show whether power is present or a power fault has occurred.

A

Green

The handle indicator lights green indicating that a valid power

 

 

source is connected to the power supply unit and that the power

 

 

supply unit is operational.

B

Flashing green

When updating the firmware of the power supply unit, the power

 

 

supply unit handle flashes green.

C

Flashing green

When hot-adding a power supply unit (PSU), the power supply unit

 

and turns off

handle flashes green five times at 4 Hz rate and turns off. This

 

 

indicates that the power supply unit is mismatched with the other

 

 

power supply unit (in terms of efficiency, feature set, health status,

 

 

and supported voltage). Replace the power supply unit that has the

 

 

flashing indicator with a power supply unit that matches the capacity

 

 

of the other installed power supply unit.
