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.
1Turn off the system and all external peripheral devices.
2Disconnect all peripheral devices from the system, except for the keyboard and the monitor.
3Make sure the system power cord is plugged into a properly grounded AC outlet and in the power cable socket.
4Make sure both the monitor and the keyboard are correctly connected to the system.
5Turn on the monitor.
6Set the display brightness and contrast controls to at least two thirds of their maximum range.
Refer the documentation that came with your monitor.
7If the operating system normally loads from the hard drive, make sure there is no diskette in the FDD and no disc in the ODD.
8If the power indicator is lit, attempt to boot from a floppy diskette or from a disc.
9Turn on the system.
If the power indicator did not light up, see the "Power indicator does not light" item on page 90.
