Recommended Operating Environment

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

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 system, place it in the environment in which 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 system 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.

Electrical Power

Good practice is to connect each power supply to a separate circuit, which enables the system to remain operational if one of the circuits fails. Consult your local electrical codes for any additional requirements.

Ambient Temperature

An ambient temperature range of 21°C (69.8°F) to 23°C (73.4°F) is optimal for system reliability. At 22°C (71.6°F) 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:

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%, and becomes critical when levels drop below 30%.

Airflow Considerations

Ensure unobstructed airflow through the chassis.

Inlet air enters at the front of the server and exits from the back.

Ventilation openings such as cabinet doors, for both the inlet and exhaust of the server should provide a minimum open area of 235 cm2 (34.3 in2) each. This equates to a 60% open area perforation pattern across the front and rear area of the server (440 mm x 89 mm; 17.3 in x 3.5 in). The impact of other open area characteristics that are more restrictive should be evaluated by the user.

Front and rear clearance of the server should allow a minimum of 5 mm (0.2 in) at the front of the system and 80 mm (3.1 in) at the rear of the server when mounted. These clearance values are based on the above 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.

Care should be taken to prevent recirculation of exhaust air within a rack or cabinet.

Cables should be managed to minimize interfering with the server exhaust vent.

Air temperature rise through the system is approximately 10°C (18°F).
