2.2.3 Preparing the System for Diagnostic Testing
Caution – Turn off devices before disconnecting cables. Before disconnecting any
peripheral cables from the system, turn off the system and any external peripheral
devices. Failure to do so can cause permanent damage to the system and/or the
peripheral devices.
1. Turn off the system and all external peripheral devices. Disconnect all of them
from the system, except the keyboard and video monitor.
2. Make sure the system power cord is plugged into a properly grounded AC outlet.
3. Make sure your video display monitor and keyboard are correctly connected to
the system. Turn on the video monitor. Set its brightness and contrast controls to
at least two thirds of their maximum ranges (see the documentation supplied with
your video display monitor).
4. Turn on the system. If the power LED does not light, see “Power LED Does Not
Light” on page 2-8.
5. If errors are encountered, power off the system, remove all add-in cards, and turn
the power back on.
