Chassis Air Flow
Air flow within the ASR 5500 complies with Telcordia recommendations to ensure vertical convection cooling
of the system.
As shown in the figure below, the lower fan trays pull ambient air inward from the front and side intake vents
located near the bottom of the chassis. The air absorbs heat from system components as it passes over them.
The upper fan trays pull heated air up through the chassis and exhaust it through the side and rear exhaust
vents located near the top rear of the chassis.
