3-2 Using the e-SAT/IN Module
Powering on the module
When all connections have been made, power on each detector connected to
the e-SAT/IN module and any devices connected to the external event
terminals. Refer to the specific guides for each device for power-on procedures.
The e-SAT/IN module has a power switch on the front panel. The switch is a
pushbutton switch that controls the power from the power supply.
• To turn the device on (1 ), press the switch once. The LED power
indicator will light.
• To turn the device off (0 ), press the switch once. The switch will
return to the extracted position, switching off the power to the unit. The
LED power indicator will extinguish.
e-SAT/IN module self-tests
1. During power-on, the e-SAT/IN module performs a series of self-tests.
The results of the tests are displayed by the green LED on the front
panel.
2. After power-on, both LEDs flash.
3. The e-SAT/IN module executes a power-on self-test (POST).
4. The sequence then requests an IP address.
5. The green LED blinks while requesting its IP address. When an IP
address is obtained, the LED becomes steady.
See table titled “Summary of LED indicators” on page 3-17 for detailed
information.
Successful power-on
When the power-on and POST sequence are successful and the module has
obtained an IP address, the green LED remains lit.
Power-on problems
