turned on. When this LED is flashing, it indicates that the server is
turned off and 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. Apower LED is also on the rear
of the server.
Note: If this LED is off, it does not mean that there is no electrical
power in the server. The LED might be burned out. To remove all
electrical power from the server, you must disconnect the power
cord from the electrical outlet.

Operator information panel
Reset button: Press this button to reset the server and run the power-on self-test
(POST). You might have to use apen or the end of astraightened
paper clip to press the button.
System-error LED: When this LED is lit, it indicates that asystem error has occurred.
An LED on the diagnostic LED panel on the side of the operator
information panel is also lit to help isolate the error (see “Light path
diagnostics” on page 18).
USB connector: You can connect aUSB device to this connector.
Release latch: Press this latch to release the operator information panel to access
the light path diagnostics LED panel.
Information LED: When this LED is lit, it indicates that anoncritical event has
occurred (see “Light path diagnostics” on page 18).

bus.
CD-ROM drive activity LED: When this LED is lit, it indicates that the CD-ROM
drive is in use.
Diskette drive activity LED: When this LED is lit, it indicates that the diskette drive
is in use.
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 aflashing status LED
depends on the SCSI controller that is connected to the hot-swap drive, as follows:
vWhen the drive is connected to the integrated SCSI controller with RAID
capabilities, aflashing status LED indicates that the drive is asecondary drive in
amirrored pair and the drive is being synchronized.
vWhen the drive is connected to an optional ServeRAID
™ controller, aslowly
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.
Hard disk drive filler panels: Afiller panel and air baffle is used to cover empty
hard disk drive bays. Afiller 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.
