6.4 UPS Communications
The Liebert PSI is equipped with a Liebert IntelliSlot port to provide advanced communication and
monitoring options.
Liebert MultiLink software continually monitors the UPS and can shut down your computer or server
via USB, contact closure and SNMP (via IS-WEBRT3 card) in the event of an extended power failure.
The Liebert IS-WEBRT3 provides SNMP and Web-based monitoring and control of the UPS across
the network.
6.5 UPS Inverter/Transfer Voltage Configurations
A two-pin DIP switch on the rear of the Liebert PSI permits setting the UPS to operate at nominal
voltages of 220V, 230V or 240V. This feature will change the high and low points at which the UPS
switches to battery power. It also will change the UPS’ output voltage when the UPS is operating in
battery mode. The factory default setting is 230 VAC.
Turn Off the UPS before making these changes to the voltage configuration.

NOTE
The USB, SNMP and contact closure communications can operate in parallel.
