Be sure that the screws are secure. Refer to Figure 21 for the screw locations.

8 Attach the PSU air baffles to the sides of the chassis, following the instructions in “Attaching the
PSU Air Baffles.”
CAUTION
Properly installed PSU air baffles prevent the hot exhaust of one system from being drawn into the air intake of an
adjacent system, and therefore protect against premature failure of the PSU. For all installations where two or more
BlackDiamond 20808 switches are installed next to each other, you must install the PSU air baffles.
Attaching the PSU Air Baffles
The air intake and exhaust vents for the BlackDiamond 20808 power supplies are on the sides of the
chassis. Attach the provided air baffles to redirect airflow from the PSU fans away from adjacent
equipment.
NOTE
Make sure that the open side of each baffle has adequate clearance to permit air intake and outflow. A minimum of
5 inches is recommended at each open side.
