2.4.6 - UPS Monitoring
The UPS has the capability of being monitored with stand alone computers, network workstations,
network servers, or UNIx hosts via the DB 9 female connector (1) located on the rear of the UPS.
The capability is used in applications requiring the UPS to provide status and power monitoring informa
tion to the computer system. For example, during a mains power failure, the information can be used
by the computer's operating system or application program to automatically save information in buffers,
to close files, and shutdown operations prior to battery capacity depletion.
Monitoring of the UPS via a computer system is easily made with a Liebert Multilink Software and a
special cable (2) shipped with the Unit.
