OMMUNICATION

This chapter 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

5.1

Liebert 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 net-

work.
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

multilink.liebert.com

5.1.1 Liebert 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 Lie-

bert MultiLink license kits, visit the Liebert Web site (

www.liebert.com

) or contact your local Emer-

son representative.

!

CAUTION

To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables 

should be segregated and run separate from all other power cables.
