5.4External Communications—Building Management Systems, Liebert SiteScan®

Liebert iCOM is capable of communicating with external monitoring systems, such as Building Man- agement Systems (BMS), Network Monitoring Systems (NMS), Liebert's SiteScan® Web system and others.

Each Liebert iCOM-controlled cooling unit is equipped with Liebert IntelliSlot plug-in slots for use with optional communication cards:

•Ethernet Web/SNMP Card

•RS-485 Modbus Card

The hot-swappable plug-in cards provide interfaces supporting open protocols, including Modbus, HTTP (Web) and SNMP. See the Liebert Web site for the latest supported protocols, Modbus refer- ence information and SNMP MIB's.

An alternative, limited method of communicating with an existing Liebert SiteScan Web monitoring system is via twisted-pair cables connected to terminals 77 and 78 on the cooling unit terminal strip. To use this method, the Liebert IntelliSlot power supply connection to P65 on the iCOM I/O board must be unplugged, and the factory-supplied 77-78 cable must be connected to P65 (follow Liebert SiteScan instructions for further connections). The appropriate Liebert iCOM control parameters will also need to be configured to utilize the terminals.

NOTE

Liebert SiteScan will be limited to legacy parameters when communicating via terminals 77 and 78.
