The MultiPort 4 card provides four sets of voltage-free contact closures for remote monitoring of
alarm conditions UPS operation On Battery and Low Battery condition. A typical application is to
allow a maximum of four computer systems to simultaneously monitor the status (e.g., utility power
failure-low battery) of a single UPS.
This card is supported in any of the three Liebert IntelliSlot bays on the Liebert NX.
