6.0 UPS monitoring
6.1 Overview
A UPS system alone provides excellent protection from brief power problems. However,
during an extended power outage an unattended computer system will eventually shut
down due to battery capacity exhaustion. To prevent data corruption when the UPS shuts
down, the computer must be informed by the UPS of
impending
shut down and take
appropriate file-saving measures. This important function is called “UPS monitoring.”
The UPS’s computer interface port is the means by which your UPS communicates with
a computer system.
Some computer operating systems have built-in UPS monitoring. These systems require
various hardware interfaces. Interface kits for all operating systems that support UPS
monitoring are available from your dealer. In addition, your dealer also offers Power-
Chute software which enhances such built-in UPS monitoring. Versions of PowerChute
are available which add the UPS monitoring function to the many operating systems
which do not inherently provide UPS monitoring.
6.2 PowerChute Software (600 VA only)
PowerChute software provides complete data protection for most operating systems. This
software is a background process that monitors the UPS through a RS-232 serial port on
the host. PowerChute offers user notification of impending shutdown, power event
logging, auto-restart upon power return and UPS battery conservation
features.PowerChute is available for many platforms including Novell, LAN Manager,
AppleShare, most UNIX-based operating systems, and DEC VAX/VMS. Please visit
