1.0 INTRODUCTION
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.
