LED Power-up Sequence

During power-up, the module goes through an initialization and self test sequence. Proper module power-up can be verified by observing the LEDs as follows:

1.The Run and Error LEDs turn on and begin blinking.

2.The Error LED will then turn off.

3.The Run LED will continue blinking.

If the module is not responding and the LEDs do not appear to be going through the appropriate initialization, call Technical Support for assistance.

NOTE: The Error LED flashes three times in sync with the Run LED when the module is formatted.

The Run LED should never stop flashing. If it stops flashing for 1.5 seconds, the watchdog timer will reset the CPU.

Fuses

The SiteGate-232 is protected by internal solid state fuses on the incoming power and CMnet. These fuses are not replaceable and will reset themselves in the event of a transitory condition.
