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 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 (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 Lie-
bert 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 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
and delivers support for built-in shutdown for AS/400 systems.
CAUTION
!
To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables
should be shielded and run separate from all other power cables, where applicable.

Remote Emergency Power Off
The UPS is equipped with a Remote Emergency Power Off (REPO) connector.
The user must supply a means of interfacing with the REPO circuit to allow disconnecting the UPS
input feeder breaker to remove all sources of power to the UPS and connected equipment to comply
with national and local wiring codes and regulations.
