	Other accessories home page contacts email		UM Link is an external SNMP agent for connecting SNMP-compatible UPS's and accessories to Ethernet. It collects data from network components (UPSs, control modules, etc.) and forwards it to SNMP Managers (such as supervision systems like NMS's or security software like UM Client).   As with any component of the MGE UPS SYSTEMS SNMP offering, UM Link integrates a TCP/IP layer and offers an exclusive system for the automatic acknowledgement of warnings, ensuring maximum security without adding to network traffic. Note: When programming the UM link using a terminal emulator, the flow control must be "no flow control". Connecting 4 UPS's using UM Link The UM Link adapter is the only external agent currently on the market that provides 4 ports for connecting UPS's. Given the relatively high cost of external agents, this configuration offers the lowest per-port connection price. In addition, it avoids an endless proliferation of boxes all over company premises. UM Link integrates a UTP and a BNC connector for connection to the network. One or other may be used, as required. Out-of-band management using a modem Thanks to the serial ports on UM Link, remote out-of-band access via modem is possible. This function is very useful when the UPS is located in a service room and cannot be connected to Ethernet. Power supply fault tolerance UM Link is fitted with two power inputs, which means that two separate electrical power sources can be used, thus securing permanent access to the connected UPS's, even if they have been shut down. It is advisable to connect one input to one of the connected UPS's and the other directly to the mains. MGE UPS SYSTEMS is the only supplier of SNMP adapters for UPS's to provide this degree of security through power supply redundancy. Updating over the network The agent and the MIB integrated in UM Link are stored in Flash memory. They can thus be updated automatically over the network, without requiring a visit to their actual location. This function is particularly useful if the company uses a significant number of SNMP agents, spread over several sites.
