5.1.1 Liebert MultiLink
Liebert MultiLink monitors the UPS continuously and can shut down your computer or server in the
event of an extended power failure. Liebert MultiLink can also be configured to shut down the UPS.
Liebert’s MultiLink can also be configured for use without the USB cable when the Liebert IntelliSlot
SNMP Card or Liebert IntelliSlot Web Card is installed in the UPS. An optional Liebert MultiLink
License Kit permits shutting down the UPS over a network.
