Another approach might be to choose a more powerful UPS, which will guarantee
a few hours of battery power. When using this approach, your software must be
able to initiate shutdown when a certain battery level is reached. The PowerChute
plus software delivered by your APC UPS supports this feature of system
shutdown. If you installed the Interface Expander in your APC UPS you can
control three systems in this way by connecting them to serial ports on the UPS.
Table 3 shows you the on-battery time for selected server models.

Basic Monitoring Ports,
