Section 1: INTRODUCTION
The Liebert OpenComms Network Interface Card provides
multiple connectivity options for your Liebert equipment.
The OpenComms Network card transforms Liebert units to
intelligent managed nodes on your network, enabling in-band
communications with network management systems (NMS). For
the first time, the system that monitors the well-being of your
computing/communication infrastructure can comprehensively
monitor your Liebert equipment as well.
The OpenComms Network card can also easily integrate to your
existing Building Management or out-of-band monitoring system
using a standard, well-defined multi-drop protocol.
The OpenComms family of interface cards communicates with
external systems via the following industry-standard open
protocols:
•
Modbus RTU over EIA-485
•
SNMP v1
•
HTTP v1.1
The OpenComms Network card is designed to provide redundant
paths for communications. This implies that it is possible to
connect to your existing BMS system using Modbus while
simultaneously communicating to your NMS through SNMP and
HTTP.
Additionally, these protocols allow simple integration into the
network and building management systems, thus leveraging prior
investment and established procedures. Even without an
installed monitoring system, Liebert units may be monitored
“on-demand” via a web browser, from anywhere network access
is permitted.
