Key Concepts continued

Low Battery	The Interface Expander generates a Low Battery signal
signal	when it detects a Low Battery condition at the UPS, regard-
	less of whether the UPS is on battery. The Interface
	Expander generates a Low Battery signal under certain
	other conditions according to the configured shutdown
	mode (see “Configuring the Interface Expander” on page
	19), when it may force a Low Battery signal and an On Bat-
	tery signal, causing the servers to shut down.

Scheduled	When a server connected to the (Advanced) computer inter-
shutdowns	face port on the UPS is running UPS-monitoring software
	such as PowerChute plus, you can execute scheduled or
	supervised UPS shutdowns for the servers connected to the
	Interface Expander. The Interface Expander intercepts the
	shutdown signal and sends the following messages to all
	attached servers or devices:
	• On Battery and Low Battery signals (for the low-bat-
	tery duration set in the UPS)
	• Shutdown commands (e.g., Sleep, Turnoff, etc., as
	requested by PowerChute plus)
	The servers connected to the Basic ports to shut down
	gracefully before they lose power when the UPS output is
	turned off — a feature normally available only to servers
	using PowerChute plus and smart signaling.
