The servers have been tested to meet all functional requirements when operating in the operating environmental limits presented in Environmental Specifications. In addition to having proper environmental conditions, keeping the server's internal temperatures within a safe operating range depends on having sufficient airflow into and out of the chassis.
Ensure that inlet air enters at the front of the server and exits from the back.
Ensure that the inlet air is within.
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. This 60% minimum open area equates to the following measurements:
Allow a minimum of 5 mm (0.2 in) clearance from the ventilation opening at the front of the server 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 - 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 and should be evaluated by the user.
Take care to prevent recirculation of exhaust air within a rack or cabinet.
Manage cables to minimize interfering with the server exhaust vent.
