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:
- Toward the front air intake of the server
- Toward the server access panels
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:
- 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.
- Ensure that inlet air enters at the front of the server and exits from the back.
- Ensure that ventilation openings such as cabinet doors, for both the inlet and exhaust of the server provide a minimum open area of 33.3 in.2 (215 cm2) each. This equates to a 60% open area perforation pattern across the front (17.5 in. x 3.2 in.) and rear area of the server (445 mm x 81 mm). The impact of other open area characteristics that are more restrictive should be evaluated by the user.
- Allow a minimum of 0.2 in. (5 mm) clearance at the front of the system and 3.1 in. (80 mm) at the rear of the server when mounted. These clearance values are based on the 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 might 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 and should be evaluated by the user.
|
- Take care to prevent recirculation of exhaust air within a rack or cabinet.
- Manage cables to minimize interference with the server exhaust vent.
- Ensure that air temperature rise through the system is approximately 59°F (15°C).
