SNMP-NET is an interface between the EnterprisePlus or Endeavor UPS and the network. It can obtain the status from a UPS and issue commands to it. SNMP-NET supports two kinds of protocol - SNMP and HTTP for user access. Through the SNMP NMS and web browser, the user can obtain the UPS status; issue commands to UPS and set-up the SNMP-NET through the network. SNMP-NET also provides shutdown software for various operating systems. The shutdown software that runs under various OS can link to the SNMP-NET automatically through the network and communicate with SNMP-NET via SNMP protocol. The shutdown software retrieves UPS information from SNMP-NET. The shutdown software will then proceed to the shutdown process in order to prevent the abnormal shutoff of host or server due to power events.
