• In a minimal UPS-based system, the degree of power failure protection is equivalent to that provided by the battery backup unit. You can, however, add more UPS devices to the system and provide reserve power to selected peripherals. Depending upon how much of the system is provided with UPS power, it can run a partial or full workload non-stop through limited periods of AC power failure.

• The UPS contains a serial I/O communications interface that, in conjunction with UPS Monitor/iX software, notifies the system operator of any problems. Like the battery backup hardware that the UPS devices replace, a system-wide power failure recovery message is broadcast to all active user terminals and to the console upon the return of power following a failure. In addition to console messages, the UPS Monitor/iX software also posts a variety of status and warning messages to the system log files which you can review and analyze to evaluate system performance.
