Introduction

1.0 INTRODUCTION

The Liebert OpenComms™ EM is a compact, half-duplex device designed to monitor temperature,

humidity, water detection and contact closure and notify personnel when those conditions exceed

user-defined limits.

The OpenComms EM is available in several models, which vary in size and number and types of

ports. All models have sensor ports to monitor temperature, humidity, water detection and contact

closure, and all models have either an external or built-in temperature/humidity sensor:

Sensor Ports

The OpenComms EM has sensor ports capable of monitoring temperature, humidity, water detection

and contact closure through sensors that may be purchased separately (see Table 3). The unit’s auto-

sensing capability can determine which type of sensor is connected, making the unit ready to plug

into your operation. Default settings for alarm limits may be changed through a Web interface.

Ethernet Ports

The unit has an Ethernet port for connection to a network, which provides access to the Web interface

and the capability of receiving alerts when monitored conditions reach alarm status. The

OpenComms EM may also be configured to send e-mail alerts and SNMP traps over the network.

Modem Port

A modem port provides the capability of sending pager messages to notify personnel of alarm condi-

tions in the monitored area.

Web Interface

A Web interface makes it easy to view monitoring data in tabular and graphic formats, configure the

device for alarm thresholds and set up automatic e-mail and pager notifications when a level in a

monitored area crosses a predefined threshold.

Serial Ports (EM PDU / vEM-14 Controllers)

EM PDU and vEM-14 controllers have two serial ports that are ideal for monitoring Liebert Managed

Power (MP) Advanced Power Strips. Power, voltage, current and temperature levels can be monitored

with user-configured alarm thresholds. In addition, some MP Advanced Power Strip models allow

each receptacle on the power strip to be turned on or off through the Web interface.

Typical Applications

An OpenComms EM is highly useful in monitoring:

•Enclosures, particularly those housing electronic equipment such as servers or telephone

switching equipment sensitive to temperature, humidity and power fluctuations

•Process Areas, such as areas where environmentally sensitive chemical reactions occur

•A closet or an area of a room where temperature levels are important, for example, an area

that houses many servers, where you want to verify the area or closet doesn’t get too hot
