5.0COMMUNICATION

This section describes UPS communication over the three types of communication connections on the rear of the Liebert® GXT3:

• Liebert IntelliSlot® port

• USB port (standard B-type)

• Terminal Block Communication

! CAUTION

To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables should be segregated and run separate from all other power cables.

5.1Liebert IntelliSlot Communication Cards

The Liebert IntelliSlot port accepts three optional cards:

Liebert IntelliSlot SNMP Card

Liebert IntelliSlot Relay Card

Liebert IntelliSlot 485 Card.

The Liebert IntelliSlot SNMP Card provides SNMP monitoring and control of the UPS across the network.

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.

The Liebert IntelliSlot 485 Card is used to connect the UPS and computer system.

Follow instructions provided with the Liebert IntelliSlot card to configure Liebert MultiLink®, the UPS or any additional ancillary product for the Liebert GXT3. These instructions are available at

5.1.1Liebert 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.

For more information about the Liebert IntelliSlot SNMP Card, Liebert IntelliSlot Web Card and Liebert MultiLink license kits, visit the Liebert Web site (www.liebert.com) or contact your local Emerson representative.
