Communication

6.4UPS Communications

The Liebert PSI XR 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.

NOTE

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

6.5UPS Inverter/Transfer Voltage Configurations

A two-pin DIP switch on the rear of the PSI XR permits setting the UPS to operate at nominal volt- ages of 110V, 120V or 127V. This feature will change the high and low points at which the UPS switches to battery power. It also changes the UPS’ output voltage when the UPS is operating in bat- tery mode. The factory default setting is 120 VAC.

Turn Off the UPS before making any changes to the voltage configuration.
