The external PoE power system has monitor function. It provides one system monitoring module, one RS232 and two RS485 monitoring interfaces. The system monitoring module reports the running information of the PSUs in the system to a fabric through RS232 or RS485 interface and indicates alarm status by the alarm LED (ALM). You can connect cables to the interfaces from the front as well as the rear of the frame.

n

The external PoE power system for the Switch 8800 Family only supports the

RS485 monitoring interface.

MBUS Introduction

The MBUS is a service-independent maintenance and test bus. No service traffic goes through the MBUS. The shutdown and reset of the MBUS does not affect the services on the switch, and faults that have occurred on modules do not affect the MBUS.

Through the MBUS, the system instructs the MBUS modules on individual cards to power on/off the cards one by one in turn, thus prevent power surging. The MBUS module software must support online upgrade.
