Hard disk drive status light:
Each of the hot-swap drives has a hard disk drive
status light. When this amber light is on continuously, the drive has failed.
Hard disk drive activity light:
Each of the hot-swap drives has a hard disk drive
activity light. When this green light is flashing, the controller is accessing the drive.
If a ServeRAID adapter is installed and this light flashes slowly (one flash per second),
the drive is being rebuilt. When the light flashes rapidly (three flashes per second),
the controller is identifying the drive.
Operator information panel
The following illustration shows the location of the status lights on the operator
information panel on the front of the server (see “Controls and indicators” on page
19).

light flashes, the server is in standby mode (the system power supply is
turned off and AC current is present). If this light is not on, the power cord is
not connected, the power supply has failed, or this LED has failed.

(POST) without any errors.
