Replacing a PSU Air Baffle
Properly installed PSU air baffles prevent the hot PSU exhaust of one system from being drawn into the
PSU air intake of an adjacent system, and therefore protect against premature thermal shutdown of the
PSU or early power supply failure. For all installations where two or more BlackDiamond 20808
switches are installed next to each other, you must install the PSU air baffles.
