Cooling Zones and Airflow Clearance

Note – Proper airflow into and out of the server is essential for keeping the server's
internal temperatures within a safe operating range.
The server draws cool air from the front of the server and expels hot air out the rear.
To avoid overheating the server:
Ensure that inlet air enters at the front of the server and exits from the back.
■
Ensure unobstructed airflow through the server.
■
Do not direct warm air toward the front air intake of the server.
■
Prevent recirculation of exhaust air within a rack or cabinet.
■
Manage cables to minimize interfering with the server exhaust vent.
■
Ensure that the server ventilation openings used for intake and outflow of air
■
provide an open area that is at least 60% of the open area perforations across the
front and rear of the server.
Allow a minimum of 5 mm (0.2 in.) clearance at the front of the system and 80 mm
■
(3.1 in.) at the rear of the server when mounted. These clearance values are based
on the preceding inlet and exhaust impedance (available open area) and assume a
uniform distribution of the open area across the inlet and exhaust areas. Clearance
values greater than these are recommended for improved cooling performance.
Note – Be mindful that the combination of inlet and exhaust restrictions, such as
cabinet doors and the spacing of the server from the doors, can affect the cooling
performance of the server.
