UPS Power Management

Automatic Shutdown of UPS-Protected Computers

NetWatch client software supports remote UPS monitoring and automatic shutdown of UPS-protected computer systems and is available on the supplied CD-ROM or from www.powerware.com.

Clients are available for the following operating systems:

:Microsoft Windows 95/98/Me/NT/2000/XP

:Novell NetWare

:UNIX (various versions, including Linux)

Each NetWatch client uses its IP address to register with a specified ConnectUPS Web/SNMP Card via the network. Once a client has registered, any change in UPS status is communicated to NetWatch. Depending on the operating system, NetWatch typically alerts the user(s) whenever the UPS begins supplying AC power from its batteries (for example, the AC line fails). Then, if AC line power does not return and the remaining battery time is low, NetWatch takes over and completes an operating system shutdown prior to the UPS running out of battery power.

Settings found in the UPS Event Actions and UPS Shutdown page and the Restart Settings page are related to the automatic shutdown of the UPS-protected computer system using NetWatch. By default, the ConnectUPS Web/SNMP Card initiates an automatic shutdown only during a low battery condition. The ConnectUPS Web/SNMP Card allows

180 seconds for the NetWatch-protected systems to complete their operating system shutdown before the UPS power is turned off. When the power returns, the UPS automatically restarts after a 30-second delay and supplies power to the load.
