The external PoE power system has the monitoring function. It provides one RS232
and two RS485 monitoring interfaces. The external PoE power supply can display
alarm information through the ALM LED. The system can learn the running information
of the rectifiers by connecting a monitoring port to the SRPU. You can use cables to
connect the monitoring ports from the front or the rear of the external PoE power
supply.
