Chassis Air Flow
Airflow within the ASR 5000 is designed per Telcordia recommendations to ensure the proper vertical
convection cooling of the system.
As shown in the figure below, the lower fan tray pulls ambient air into the chassis from the front and side
intake vents located at the bottom of the chassis. The air is pushed upwards through the system and absorbs
heat while passing over system components.
Total air flow exiting the chassis is approximately:
•
275CFM (7.8 cubic meters/minute)
–
Low fan speed
•
565CFM (16 cubic meters/minute)
–
High fan speed
