Automatic Shutdown of UPS-Protected Computers
NetWatch client software supports remote UPS monitoring and automatic shutdown of UPS-protected
computer systems and is available from www.eaton.com/powerquality under Software Downloads.
Clients are available for many operating systems, including:
l
Microsoft Windows
l
Novell NetWare
®
l
Linux
®
l
UNIX
l
Mac OS X
Check www.eaton.com/powerquality for a complete listing of supported operating systems.
Each NetWatch client uses its IP address to register with a specified PXGX UPS Card through the network.
After 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 NetWatch Configuration page are related to the automatic shutdown of the
UPS-protected computer system using NetWatch.
