Chapter 3. Server controls, LEDs, and power
This section describes the controls and light-emitting diodes (LEDs) and how to turn
the server on and off.
Front view
The following illustration shows the controls, LEDs, and connectors on the front of
the server.

activity LED
Operator information panel: This panel contains controls, indicators, and a USB
port. Swing it open to see the light path diagnostics LEDs on the side of the panel.
See “Operator information panel” on page 33 for details.
Diskette drive activity LED: When this LED is lit, it indicates that the diskette drive
is in use.
CD-ROM drive activity LED: When this LED is lit, it indicates that the CD-ROM
drive is in use.
Hard disk drive filler panels: A filler panel and air baffle are used to cover empty
hard disk drive bays. A filler panel and air baffle must be installed in each empty
bay to ensure proper system cooling. Your server comes with five filler panels and
air baffles installed, and one completely empty bay.
Hard disk drive activity LED: When this LED is flashing, it indicates that the
associated hard disk drive is in use.
Hard disk drive status LED: When this LED is lit continuously, it indicates that the
associated hard disk drive has failed. The interpretation of a flashing status LED
depends on the SCSI controller that is connected to the hot-swap drive, as follows:
v When the drive is connected to the integrated SCSI controller with RAID
capabilities, a flashing status LED indicates that the drive is a secondary drive in
a mirrored pair and the drive is being synchronized.
v
When the drive is connected to an optional ServeRAID controller, a slowly
flashing (one flash per second) status LED 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.
