Enterprise networks Rated at up to 520W from 36V and up to 760W from 50 to 60V , the IBC IN IN Optical access networks conforms to an industry standard quarter-brick footprint while supplying power greatly exceeding competitive quarter-bricks. Its leading efficiency enables full load operation Storage networks at 45C with only 400LFM airflow. Its small cross section facilitates unimpeded airflow Automated test equipment above and below its thin body to minimize the temperature rise of downstream components. A baseplate option is available for alternative cooling schemes.
