Emerson MONITORING OpenComms Manuel D’Utilisation

The OpenComms NIC Card transforms Liebert units into manageable 

nodes within your Network, NMS, and BMS systems.
The OpenComms NIC Card contains a standard Ethernet and EIA-485 

(2-wire) port designed to support viewing and management through:

• HTTP for Web browsers (I.E. 5.5 or later)
• SNMP (v1, v2c) for network management systems
• Modbus RTU for building management systems (and SiteScan)

For the first time, the system that monitors the status of your comput-

ing, communication and facility infrastructure can comprehensively 

monitor your Liebert equipment concurrently.
These standard open protocols allow simple integration into your mon-

itoring system, leveraging prior infrastructure investments and estab-

lished procedures.
