Front Panel Operations

The following paragraphs detail the power-up process and then describe the menu
system, the picture adjustments, and selection of executive mode.

Power

Power is automatically applied when the power cord is connected to an AC source.
When AC power is applied, the switcher performs a self-test that blinks all of the
front panel LEDs and then lights only the LEDs for the previously selected output
and the tied input. The self-test also displays the model name, part number, and
the firmware version in the LCD display. After approximately 2 seconds, the LCD
reverts to its default display cycle, alternating between two displays: one showing
the inputs selected for outputs 1 and output 2, and the other showing the selected
output rates (figure 3-6). An error-free power up self-test sequence leaves all of the
LEDs off, with the exception of the selected output's and input's LEDs, off and the
LCD cycling through the default displays.

latest configuration is retrieved.
