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
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

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.
