General Site Preparation Notes

Your environmental control system must provide intake air for the server that complies with the limits specified in Environmental Specifications.

To avoid overheating, do not direct warmed air:

Note - When you receive your server, place it in the environment in which you will install it. Leave in its shipping crate at its final destination for 24 hours. This resting period prevents thermal shock and condensation.

The server has been tested to meet all functional requirements when operating in the operating environmental limits presented in Environmental Specifications. 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.

Ambient Temperature

An ambient temperature range of 69.8°F (21°C) to 73.4°F (23°C) is optimal for system 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.

Ambient Relative Humidity

Ambient relative humidity levels between 45% and 50% are the most suitable for data processing operations in order to:

Electrostatic discharge (ESD) is easily generated and less easily dissipated in areas where the relative humidity is below 35%, and becomes critical when levels drop below 30%.

Airflow Considerations

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.
