Operating Environment Requirements; Airflow Considerations - Sun Oracle SPARC T3-1 Installation Manual

Operating Environment Requirements

Your environmental control system must provide intake air for the servers that
complies with the limits specified
To avoid overheating, do not direct warmed air:
Toward the front air intake of the server
■
Toward the server access panels
■
Note – When you receive your server, place it in the environment where you will
install it. Leave it in its shipping crate at its final destination for 24 hours. This resting
period prevents thermal shock and condensation.
The servers have been tested to meet all functional requirements when operating in
the operating environmental limits presented
page 6. Operating computer equipment in extremes of temperature or humidity
increases the failure rate of hardware components. To minimize the chance of
component failure, use the server within the optimal temperature and humidity
ranges.

Airflow Considerations

Proper airflow into and out of the server is essential for keeping the server's internal
temperatures within a safe operating range.
Ensure unobstructed airflow through the chassis.
■
Ensure that inlet air enters at the front of the server and exits from the back.
■
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
