Liebert MultiLink monitors the UPS continuously and can shut down a computer or server in the 
event of an extended power failure.
Liebert MultiLink can also be configured for use without the USB cable when the Liebert IntelliSlot

SNMP/Web card is installed in the UPS. Additionally, Liebert MultiLink can be configured to coordi-
nate shutdown across the network with other computers running Liebert MultiLink when you pur-
chase a Liebert MultiLink License Kit. For more information about the Liebert IntelliSlot SNMP/Web 
Card and Liebert MultiLink License Kits, visit our Web site (

dealer or Emerson representative.
Several option cards are available for use in the Liebert IntelliSlot port of the Liebert GXT3

UPS across the network.
The Liebert IntelliSlot MultiPort 4 Card allows installing Liebert MultiLink software on four comput-
ers and coordinate shutdown in the event of a power failure.
The Liebert IntelliSlot Relay Card provides dry contact relay outputs for custom wired applications
