Rackmount Filler Panels not only dress up your rack cabinet and give it that “finished” look, but are also important for managing airflow in and through your cabinet. One of the greatest challenges in operating rackmounted servers is thermal management. Overheated servers are less reliable and fail sooner, but the addition of a few filler panels can prevent the recirculation of heated exhaust air from the rear to the front of your rack cabinet, allowing your servers to take in the cool air. This is especially effective in warm aisle / cool aisle server rooms. CCSI has all sorts of Filler Panels; solid, slotted, perforated and louvered in 1U, 2U, 3U, 4U, 5U, 6U and 7U panel sizes. We also have 2U; 3U and 4U fan panels to increase airflow through your rack.
