Communication

6.3.1Liebert® 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.

! 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.

6.4Remote 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.
