Hardware diagnostic testing
This section provides a detailed approach to identifying a hardware
problem and its cause.
Checking the boot-up status
Caution: Before disconnecting any peripheral cables from the
server, turn off the system and any peripheral devices. Failure to
do so can cause permanent damage to the system and/or the
peripheral device.
1 Turn off the system and all external peripheral devices.
2 Disconnect all peripheral devices from the system, except for the
keyboard and the monitor.
3 Make sure the system power cord is plugged into a properly
grounded AC outlet and in the power cable socket.
4 Make sure both the monitor and the keyboard are correctly
connected to the system.
5 Turn on the monitor.
6 Set the display brightness and contrast controls to at least two
thirds of their maximum range.
Refer the documentation that came with your monitor.
7 If the operating system normally loads from the hard drive, make
sure there is no diskette in the FDD and no disc in the ODD.
8 If the power indicator is lit, attempt to boot from a floppy diskette
or from a disc.
9 Turn on the system.
If the power indicator did not light up, see the "Power indicator
does not light" item on page 90.
