Server Tech Rack Environmental Monitoring (EMCU-1-1B)

Please note, the Server Technology EMCU-1-1B has been discontinued. For the direct replacement, please see the Server Technology EMCU-1-1C.

The Server Technology EMCU-1-1B isan IP-based solution for monitoring environmental conditions within the cabinet of your data center. 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 infrastructure. Monitoring temperature in equipment cabinets is vital to the server's performance and controlling infrastructure cooling costs.

Each EMCU supports:

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

The Environmental Monitoring Control Unit monitors vital environmental conditionsand prevents environmental conditions from exceeding recommended thresholds to protect the assets from harmful elements. 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 Server Technology's IP CDUs.
