Liebert MultiLink

Liebert MultiLink continually monitors the UPS and can shut down your 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
coordinate shutdown across the network with other computers running Liebert MultiLink when you
purchase a Liebert MultiLink License Kit. For more information about the Liebert IntelliSlot
SNMP/Web Card and Liebert MultiLink License Kits, visit our Web site (www.liebert.com) or
contact your local dealer or Emerson representative.
Several option cards are available for use in the Liebert IntelliSlot port of the Liebert GXT3. The
Liebert IntelliSlot SNMP/Web Card provides SNMP and Web-based monitoring and control of the
UPS across the network.
The Liebert IntelliSlot MultiPort 4 Card allows installing Liebert MultiLink software on four
computers and coordinate shutdown in the event of a power failure.
The Liebert IntelliSlot Relay Card provides dry contact relay outputs for custom wired applications
and delivers support for built-in shutdown for AS/400 systems.
