Preparing the System for Diagnostic Testing

CAUTION Turn off devices before disconnecting cables: Before disconnecting any peripheral cables from
the server, turn off the server and any external peripheral devices. Failure to do so can cause
permanent damage to the server and/or the peripheral devices.
Check the following:
1. Turn off the server and all external peripheral devices. Disconnect all of them from the server, except the
keyboard, mouse, and video monitor.
2. Make sure the server input power is properly connected.
3. Make sure your video display monitor, keyboard, and mouse are correctly connected to the server. Turn
on the video monitor. Set its brightness and contrast controls to at least two thirds of their maximum
ranges (refer to the documentation supplied with your video display monitor).
4. If the operating system normally loads from the hard disk drive, make sure there is no diskette in drive
A. Otherwise, place a diskette containing the operating system files in drive A.
5. Turn on the server. If the power LED does not light, refer to Power Light Does Not Light on page 75.
6. If errors are encountered, power off the server and remove all add-in cards.
