EOTec 2104 Ring Switch Hardware 

 

OK Output Alarm (Global Alarm Relay) 

All EOTec 2104 Ethernet Ring Switch models have an 

OK

 output alarm. 

The 

OK

 output alarm normally is activated if any of the user-configurable alarm 

conditions occurs, such as a loss of primary DC power or a communication failure in the 
ring port(s). You can configure the functionality of this alarm using the EOTec 2104 
Switch Tools utility.
