4.6 SmartSlot for APC Silcon 240-320kW UPS
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.
