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 display monitor.

3 Make sure the system power cord is plugged into a properly

grounded AC outlet and in the power supply module cord socket.

4 Make sure the display monitor and keyboard are correctly

connected to the system.

5 Turn on the display 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 display monitor.

7 If the operating system normally loads from the hard drive, make

sure there is no diskette in floppy drive and no disc in the optical

drive.

8 If the power indicator is lit, attempt to boot from a disc.

9 Turn on the system.

If the power indicator did not light up, see “Power indicator does

not light” on page 111.
