Electronic systems based on 1U chassis design have become one of the most important platforms used for servers, industrial electronics, information technology (IT) and telecommunication equipment. 1U chassis are sometimes referred to as “Pizza Boxes”. BS EN 60297-3-105 specifies the dimensions for 1U chassis, mounted into IEC 60297-3-100 compliant racks/cabinets where dimensions, loaded weight and accessibility require differing assembly methods.
As defined in the IEC 61587 series, BS EN 60297-3-105 provides guidance for cooling and reference for EMC, seismic along with climatic and mechanical requirements and tests. The drawings used in BS EN 60297-3-105 do not indicate product design. Only the specific dimensions are used. The terminology in BS EN 60297-3-105 complies with IEC 60917-1.
BS EN 60297-3-105 on the dimensions of 1U high chassis is useful for:
Electronic equipment is used in applications that rely on mechanical or electric systems for their operation. They are essential to any work on electronics systems for creating signals and capturing responses from electronic devices. There are certain specifications regarding the performance of electronic equipment. Applications for 1U chassis designs are widespread and solutions are found in every segment of the electronics industry.
BS EN 60297-3-105 gives guidance and provide dimensional requirements for 1U chassis based on weight loading, physical size and service accessibility.
In BS EN 60297-3-105, various chassis types are identified according to application needs. The defined interface dimensions of the various chassis types permit the development of common mounting accessories. BS EN 60297-3-105 provides you with the clarification and the application-specific chassis type choice which helps you address the serviceability and airflow aspects of the chosen 1U chassis.
Similar attributes for multiple unit high equipment may be derived from BS EN 60297-3-105. The economical value of BS EN 60297-3-105 lies in the predefined interface dimensions of the chassis for which suitable accessories may be developed. In addition, BS EN 60297-3-105 indicates the cooling possibilities as a consequence of the chosen mounting support.
The guidelines in BS EN 60297-3-105 enables you to provide a superior quality product to your end-users.
