Verifying Proper Operation Of The Server Lights; Specific Problems And Corrective Actions - Intel AC450NX Product Manual

Verifying Proper Operation of the Server Lights

As POST determines the server configuration, it tests for the presence of each mass storage device
installed in the server. As each device is checked, its activity light should turn on briefly. Check
for the following:
Does the diskette drive activity light turn on briefly? If not, refer to "Diskette Drive Activity
Light Does Not Light" on page 268.
If there is a hard disk drive or a SCSI device installed in the server, does the drive activity light
on the front panel turn on briefly? If not, refer to "Hard Disk Drive Activity Light Does Not
Light" on page 268.
NOTE
For information about the controls and indicators, see Chapter 1.
Confirming Loading of the Operating System
Once the server boots up, the operating system prompt appears on the screen. The prompt varies
according to the operating system. If the operating system prompt does not appear, refer to "Initial
Startup of the Server" on page 262.
