3 Using the DEU

Power-On Self Diagnostics

When the DEU is powered on, it will perform a power on self-test (POST) procedure. If no errors are detected, all of the Status Indicator LEDs will illuminate solid green.

During the diagnostic self-test a continuous tone will sound and the following will be observed:

The Operator Control Panel will display “Testing ROM”, “NVRAM”, and “SCSI Access” followed by the startup mode screen and the Status OK (default) screen, provided no errors are detected. The Status Indicator LEDs will be as follows:

Fan Status LED will be solid amber and change to solid green

TPower Supply LED will be solid green

Channel Mode LED will be solid amber and change to solid green

In addition to the LED indications, the POST procedure can be monitored from the Operator Control Panel.

The results of the test can be viewed from the Operator

Control Panel by selecting “Hardware Menu” at the

Main Menu and then choosing “POST Results”, see

Operator Control Panel described later in this guide.
