Server controls and indicators

This section identifies the controls and indicators on the front of your server.

CD-ROM eject button

CD-ROM drive activity light

Diskette-eject button

Diskette drive activity light

SCSI activity light

Power-on light

Power-control button

System error light

CD-ROM eject button: Press this button to release a CD from the drive.

CD-ROM drive activity light: When this light is on, it indicates that the CD-ROM drive is in use.

Diskette-eject button: Press this button to release a diskette from the drive.

Diskette-drive activity light: When this light is on, it indicates that the diskette drive is in use.

SCSI activity light: When this green light is flashing, the controller is accessing a SCSI device; for example, a hard disk drive.

Note: Hot-swap hard disk drives also have an activity light. This light is also known as the SCSI hard disk drive activity light.

If your server has a ServeRAID™ controller 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.

Power-on light: When this green light is on, system power is present in the server.

Power-control button: Press this button to manually turn the server on or off.

System error light: When this amber light is on, it indicates that a system error has occurred. An amber error light on the interior of the server, adjacent to the faulty component, will also be on to further isolate the error. (For more information, see “Chapter 6. Solving problems,” on page 73.)
