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.
