.
STANDBY
With the power cord connected, the circuit breaker closed, and the
front panel switch in the standby position (status light off), the chassis is in
STANDBY mode. Although no power is supplied to the ESM and installed modules
when in Standby, the chassis is energized and consumes power. Chassis fans will
not operate, but internal PSU (power supply unit) fans may come on.
ON With the power cord attached, circuit breaker closed, and the front panel
switch in the
ON
position (status light on or blinking), the chassis is
ON
. Power is
supplied to the ESM and installed modules. Fans will operate as dictated by
chassis thermal load.

ON/STANDBY
switch is located on the ESM module. It is lit when the
chassis is ON . The
STATUS
light in the ESM’s
ON/STANDBY
switch cycles as
