The following information gives details about the controls, LEDs, and connectors on
the front of the server.
Hot-swap hard disk drive activity LED: This LED is used on SCSI hard disk
drives. Each hot-swap hard disk drive has an activity LED, and when this LED is
flashing, it indicates that the drive is in use.
Hot-swap hard disk drive status LED: This LED is used on SCSI hard disk
drives. When this LED is lit, it indicates that the drive has failed. If an optional IBM
ServeRAID
™
controller is installed in the server, when this LED is flashing slowly
(one flash per second), it indicates that the drive is being rebuilt. When the LED is
flashing rapidly (three flashes per second), it indicates that the controller is
identifying the drive.
DVD-eject button: Press this button to release a DVD or CD from the DVD-ROM
drive.
DVD-ROM drive activity LED: When this LED is lit, it indicates that the DVD-ROM
drive is in use.
Note: The DVD-ROM option is available only on the 3.5-inch drive configurations
(either SCSI or SATA hard disk drives).

server is turned on. When this LED is flashing, it indicates that the server is
turned off and is still connected to an ac power source. When this LED is off, it
indicates that ac power is not present, or the power supply or the LED itself has
failed. A power LED is also on the rear of the server.
