Ethernet UPS Discovery

An Uninterruptible Power Supply (UPS) is a device which maintains a continuous supply of electric power to connected equipment by supplying power from a separate source when utility power is not available. A small business office may have many servers managed by a variable number of UPS devices, possibly from different vendors. UPS management by a system administrator is often done using vendor tools to do power management, alerts, or other UPS management operations. Operators must often correlate a server with the UPS to which attached. Operators must often manually determine the UPS and its server connection. This process can be tedious and error prone. Servers will establish communication with the UPS in order to receive power or error alerts directly, helping to guarantee clean power-off in the case of utility failure. Current implementations for the discovery and alert management of UPS devices include:

Server and UPS devices are connected using the serial (RS232) cable. All the commands are sent using the serial interface. The server has UPS agents running that are managed by the user.

Server and UPS device are connected using a USB cable. All commands are sent using the USB cable. The server has UPS agents running that are managed by the user.

Software running on the server discovers all UPS devices and their parameters using the Simple Network Management/Service Location protocols (SNMP/SLP); both server and UPS devices are connecte...
