The SR-210 is a Smart Rack Management and Control Unit that transforms a standard equipment rack into a smart-rack by monitoring temperature and other aspects of the rack and notifying the administrator in case of alarms.
The SR-210 is designed to monitor and control the temperature of an equipment rack by automatically activating or de-activating the rack ventilation fans to achieve the user desired temperature inside the rack.

The device also has 4 binary inputs for sensing dry contact relays and 2 potential inputs with timestamping, which can be connected to alarms such as rack door-open alarm, smoke alarm, water-level alarm, or dry contact relays from the equipment installed in the rack to provide equipment failure alarms. The users can monitor the status and modify the parameters of multiple racks, remotely, from a centralized location through the Unified NMS.
