3. To use the test, press the different keys on the keyboard. The picture on the screen
should highlight the key that you press.
If the graphic doesn’t reflect the key you press, you may have a problem with the
keyboard or with the cable that connects the keyboard to the system.
If you’re using a keyboard other than one supplied by Silicon Graphics, the key
layout may be different.
Close the keyboard test by clicking on the button in the upper left-hand corner of
the keyboard graphic and selecting Quit. The screen goes back to the way it was
before you launched the confidence test.
If your keyboard does not work, follow the instructions in “Ordering Replacement
Parts” on page 135 to order a replacement part. Then contact your service provider
for further instructions.
Monitor
If the monitor isn’t working or the display is distorted, first check the cable that connects
the monitor to the system. Also check to make sure the brightness knob is providing
sufficient light to the screen, that the monitor video cable is firmly connected to both the
monitor and the Indigo chassis, and the thumbscrews are screwed in all the way.
