6.2.1 System Power Up with Heaters
1. Press the power button (item 1) to initiate computer cold start up.

ON first to bring the inside temperature of the housing up to a safe startup temperature
before allowing the computer to power up.
3. On the keypad, the red heater LED (item 4) illuminates solid when the heaters are working,
and the green power LED (item 2) flashes in quick, half-second intervals to show that the

(-4°F).

solid green when the computer is powered up and ready.
6. In the unlikely event the temperature inside of the cabinet drops below -20°C while the
computer is on, the heaters will cycle on and off as necessary to maintain a safe operating
temperature while the computer remains operational.
