Agency Compliance - Sun Microsystems Server X4-2 Installation Manual

Ensure that ventilation openings such as cabinet doors, for both the inlet and
■
exhaust of the server are not obstructed. For example, Oracle's Sun Rack II has
been optimized for cooling. Both the front and rear doors have 80 percent
perforations that provide a high level of airflow through the rack.
Ensure that front and rear clearance of the server allow a minimum of 1 inch (2.5
■
mm) at the front of the server and 3.15 inch (80 mm) at the rear of the server when
mounted. These clearance values are based on the inlet and exhaust impedance
(available open area) stated above and assume a uniform distribution of the open
area across the inlet and exhaust areas. These values also improve 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. You must evaluate these restrictions. Server placement is particularly
important for high-temperature environments.
Take care to prevent recirculation of exhaust air within a rack or cabinet.

Manage cables to minimize interference with the server exhaust vent.
