This section describes the four types of communication ports on the rear of the UPS:

• Liebert IntelliSlot

port

• USB port (standard B-type)

• Terminal Block Communication

•RS232 port (DB9F)

5.1 Liebert IntelliSlot Communication Cards

The Liebert IntelliSlot port accepts four optional cards:

• Liebert IntelliSlot Web Card (IS-WEBCARD)

• Liebert IntelliSlot Relay Card (IS-RELAY)

• Liebert IntelliSlot MultiPort Card (IS-MULTIPORT)

• Liebert IntelliSlot Unity Card (IS-UNITY-DP)

The Liebert IntelliSlot Web 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 Liebert MultiLink

shutdown software.

The Liebert IntelliSlot MultiPort Card provides four sets of contacts for support of up to four

computers that have Liebert MultiLink installed.

The Liebert IntelliSlot Unity Card provides SNMP and/or RS-485 monitoring of the UPS across the

network and/or building management system. The Liebert IntelliSlot UNITY card also enables

monitoring external temperature, humidity and contact closure inputs using external sensors. (The

Liebert IS-UNITY-DP compatibility will be a future release, contact your Emerson sales

representative for availability.)

Follow instructions provided with the Liebert IntelliSlot card to configure Liebert MultiLink

, the

UPS or any additional ancillary product for the Liebert GXT4. These instructions are available at:

multilink.liebert.com

5.1.1 Liebert MultiLink

Liebert MultiLink monitors the UPS continuously and can shut down the computer or server in the

event of an extended power failure. Liebert MultiLink can also be configured to shut down the UPS.

Liebert MultiLink can communicate with the UPS via the USB port, RS232 port, contact closures via

terminal block or over the network via SNMP using the Liebert IS-WEBCARD. An optional Liebert

MultiLink license kit permits shutting down multiple computers that are protected by the UPS.

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.

5.2 USB Port Communication

The standard B-type USB port is used to connect the UPS and network server or other computer

system using Liebert MultiLink

A standard B-type USB port is provided to allow connection to a computer or network server. The

USB port can be used to communicate with the Liebert GXT4 configuration program (see

section5.2.1 - Configuration Program for details) or Liebert MultiLink (refer to 5.1.1 - Liebert

MultiLink for description) that is provided on the CD that is included with the UPS.

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