The Liebert PSI
™
XR is a 2U, line-interactive UPS that may be installed in a rack or used as a tower
UPS.
Status indicators on the front of the Liebert PSI XR display load level, battery level, buck/boost, site-
wiring fault and battery status. Controls include a combination ON/ Alarm Silence/Manual Self-Diag-
nostic button, an Off button and a Display Status Change button.
The Liebert PSI XR has USB, DB-9 (RS-232/contact closure) and SNMP interface ports. The DB-9
and USB ports provide detailed operating information including voltages, currents, and alarm status
to the host system when used in conjunction with Liebert shutdown software.
