Optimal Ambient Temperature
An ambient temperature range of 69.8˚F (21˚C) to 73.4˚F (23˚C) is optimal for server
reliability. At 71.6˚F (22˚C) it is easy to maintain safe relative humidity levels.
Operating in this temperature range provides a buffer if the environmental support
systems fail.

Optimal Ambient Relative Humidity
Ambient relative humidity levels between 45 percent and 50 percent are the most
suitable for data processing operations in order to:
■
Prevent corrosion
■
Provide an operating time buffer in the event of environmental control system
failure
■
Help avoid failures caused by the intermittent interference from static discharges
that occur when relative humidity is too low
Electrostatic discharge (ESD) is easily generated and less easily dissipated in areas
where the relative humidity is below 35 percent. ESD risk becomes critical when
levels drop below 30 percent.

Airflow Considerations
Optimize airflow and cooling by reviewing the following list of considerations.
■
Ensure unobstructed airflow through the chassis. The server uses internal blowers
that can achieve a total airflow of 160 CFM in normal operating conditions.
■
Ensure that inlet air enters at the front of the server and exits from the back.
