Environmental Monitoring
Protect your investment in IT and network hardware with an IP-based environmental monitor. Receive SNMP-based alarms when temperature, humidity, water detection and contact closures vary from defined conditions.

IP-based Solution for Monitoring Environmental Conditions in the Data Center Equipment Cabinet.  Ever increasing densities of vertically racked servers conserve valuable floor space in the data center, but the resulting power consumption and heat dissipation create new concerns for data center managers. Environmental Monitoring, particularly temperature & humidity, is a must for any sensitive infrastructure. Monitoring temperature in equipment cabinets is vital to the server's performance and controlling infrastructure cooling costs. The Environmental Monitoring Control Unit (EMCU) monitors vital environmental conditions in the equipment cabinet. Prevent environmental conditions from exceeding recommended thresholds and protect the equipment cabinet's assets from harmful elements.


Each EMCU supports:

  • 2 Additional temperature and humidity measurements
  • Water sensor
  • 4 Dry contact closure door sensors

The EMCU-1-1B assures network managers that environmental conditions are within defined tolerances and that unauthorized entry into the equipment cabinets does not go unnoticed. The EMCU-1-1B can be located in data centers, co-lo sites, web hosting facilities, telecom switching sites, POP sites, server closets, and any unmanned area that needs to be monitored. Install the EMCU-1-1B in the equipment cabinet and gain access to environmental conditions from a web or serial interface through one of Servertech's IP address-able CDUs.
