The Liebert RDU-S is a compact rack processing unit designed to monitor the environment in electronic equipment racks and rooms through various types of sensors and cameras. The unit can accommodate multiple sensors, such as temperature, humidity, water, smoke, motion and door sensors. It can also be used for remote notification such as activating a beacon light to report problems. The compact design makes it suitable for installation in a rack, where it takes up little space, or it may be mounted on a wall for access without opening the equipment rack.

  • Web interface allows real-time site monitoring and control.
  • Detect and be notified of critical conditions for parameters such as temperature and humidity within data centers and individual racks.
  • Export historical data and analyze for trends to help avoid the same issues in the future.
