Uninterruptible power supply (English Wikipedia)

APC AP9207 Share-UPS, User Manual, pp. 6–7, Port 1 is called the Advanced port because it supplies smart signaling, which provides the advanced capabilities available to a server running PowerChute plus software. The Advanced port provides full access to the Computer Interface port of the UPS. Ports 2–8 on the rear panel of Share-UPS are called Basic ports because they supply simple UPS signaling for On Battery and Low Battery conditions in the UPS. "Share-UPS User Manual" (PDF).
