iDRAC Direct LED indicator codes

The iDRAC Direct LED indicator lights up to indicate that the port is connected and is being used as a part of the iDRAC subsystem.

NOTE:

The iDRAC Direct LED indicator does not turn on when the USB port is used in the USB mode.

Overview

Condition

A valid power source is connected to the PSU and that the PSU is operational.

When hot-adding a PSU, the PSU indicator flashes green. This indicates that there is a

PSU mismatch with respect to efficiency, feature set, health status, and supported

voltage. Ensure that both the PSUs are of the same capacity.

Indicates a problem with the PSU.

CAUTION:

When correcting a PSU mismatch, replace only the PSU with the

flashing indicator. Swapping the PSU to make a matched pair can result in an

error condition and unexpected appliance shutdown. To change from a High

Output configuration to a Low Output configuration or vice versa, you must

turn off the appliance.

CAUTION:

If two PSU are used, they must be of the same type and have the

same maximum output power.

CAUTION:

Combining AC and DC PSU is not supported and triggers a

mismatch.

Power is not connected.
