Monitoring POST
See Chapter 3, "Configuration Software and Utilities," beginning on page 31.
Verifying Proper Operation of Key System Lights
As POST determines the system configuration, it tests for the presence of each mass storage device
installed in the system. As each device is checked, its activity light should turn on briefly. Check
for the following:
Y
Does the diskette drive activity light turn on briefly? If not, see "Diskette Drive Activity Light
Y
Does Not Light" on page 128.
If a second diskette drive is installed, does its activity light turn on briefly? If not, see
"Diskette Drive Activity Light Does Not Light" on page 128.
Y
If there is a hard disk drive or SCSI devices installed in the system, does the hard disk drive
activity light on the control panel turn on briefly? If not, see "Hard Disk Drive Activity Light
Does Not Light" on page 129.
Confirming Loading of the Operating System
Once the system 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, see "Initial
System Startup" on page 123.
