8 External Monitoring andBuilding ManagementSystems
Vertiv™ Liebert® iCOM™-controlled cooling units are equipped with embedded 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:
NOTE: Because the Liebert® iCOM™ U2U network must be separate from other networks, use external monitoring or
BMS to communicate securely between networks.
• Velocity Protocol for Vertiv™ Trellis™, Vertiv™ Liebert® SiteScan™ and Vertiv™ Liebert® Nform.
• Embedded Vertiv™ LIFE™ Technology for Remote Service Delivery.
• SNMP (v1/v2/v3) for NMS.
• HTTP/HTTPS for web page viewing.
• SMTP for e-mail.
• SMS for mobile messaging.
• Modbus RTU-Modbus Remote Terminal Unit communication protocol for BMS over an RS-485 serial
network (Modbus RTU RS-485).
• Modbus TCP-Modbus 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
