External Monitoring And Building Management Systems; Bms And Vertiv™ Liebert® Intellislot Settings; Configuring Bms Communication With Embedded Unity - Vertiv Liebert iCOM Installer/User Manual

7 External Monitoring and Building Management Systems
Vertiv™ Liebert® iCOM™ controlled cooling units are equipped with embedded Vertiv™ Liebert® IS-Unity-DP software to communicate with external
monitoring systems including Building Management Systems (BMS), Network Monitoring Systems (NMS) and Vertiv™ Liebert® SiteScan™ Web.
Embedded Unity communicates with multiple third-party protocols to monitor and manage a range of parameters and events. The Embedded Unity software
delivers:
• Velocity protocol for Vertiv™ Liebert® Trellis™, SiteScan™, and Nform.
• Embedded LIFE™ Technology for Remote Services
• SNMP (v1/v2/v3) for NMS.
• HTTP/HTTPS for web page viewing.
• SMTP for e-mail.
• SMS for mobile messaging.
• Modbus RTU—Remote Terminal Unit. (MODBUS RTU RS-485)
• Modbus TCP Transmission Control Protocol for BMS over Internet or LAN.
• BACnet IP—BACnet over Internet Protocol for BMS over Internet or LAN.
• BACnet MSTP—BACnet Primary-Secondary/Token-Passing communication protocol for BMS over an RS-485 serial network (Modbus MSTP
RS-485).
7.1 BMS and Vertiv™ Liebert® IntelliSlot Settings
When communicating with a building management system (BMS) with an optional IntelliSlot Unity card or via embedded Unity function, the BMS settings are
identical and include:
• Disconnect fail safe
• Manual pump speed control
• Allowing the BMS to change pump speed
• Backup pump and temperature control

7.1.1 Configuring BMS Communication with Embedded Unity

By default, built-in Unity function is disabled. You must enable communication with the BMS via the IS-UNITY options in iCOM™.
To configure Modbus, BACnet, SNMP, SMS and HTTP communication, see
