Eca-310-e Pdf - Eia
Specifies thread types: #10-32 UNF and 12-24 UNC for racks; M6 x 1 for metric equivalents. It also defines screw lengths, washer requirements, and tightening torques.
Defines the standard’s applicability to racks, cabinets, panels, and chassis used for electrical and electronic equipment. It explicitly covers both 19-inch and 23-inch mounting widths.
When a technician searches for the , they are usually looking for specific dimensional data. The standard covers several critical aspects of rack design: Eia Eca-310-e Pdf
The most ubiquitous legacy of this standard is the definition of the "Rack Unit" or "U." The formally defines the height of a single Rack Unit (1U) as 1.75 inches (44.45 mm). This standardization allows a server manufactured in California to fit perfectly into a rack manufactured in Singapore. Without the precise definitions found in this document, the modularity of modern data centers would not exist.
Released in December 2005, the EIA/ECA-310-E standard defines the physical requirements for . It is the most recent evolution of the original EIA-310-D standard, primarily introducing minor refinements and nomenclature changes as the governing bodies evolved from the Electronic Industries Association (EIA) to the Electronic Components, Assemblies & Materials Association (ECA). The Universal Blueprint Specifies thread types: #10-32 UNF and 12-24 UNC
The standard defines several critical dimensions that every "EIA-compliant" rack must follow: Go to product viewer dialog for this item. ECIA EIA/ECA-310-E
Precision is key in high-density deployments. The standard outlines the "pitch" or the vertical distance between mounting holes. The revision clarifies these dimensions to ensure that mounting hardware aligns across multiple manufacturers. It explicitly covers both 19-inch and 23-inch mounting
The magic of 310-E lies in its precise measurements. It standardizes the features of the "19-inch rack"—the industry benchmark for IT infrastructure:
If you are designing, purchasing, or installing server racks, network cabinets, or electronic enclosures, the official serves as your definitive reference. Here is why:
The document details the dimensions of the mounting rails—the vertical metal strips inside a rack where equipment is screwed in. It specifies the hole patterns, including the distinct square holes used for cage nuts and the round holes used for screws with clip nuts. The ensures that the horizontal spacing between these rails remains consistent (commonly 19 inches or 23 inches), preventing equipment from being too wide or too narrow for the enclosure.
The standard is the industry benchmark for the mechanical design of 19-inch racks, cabinets, panels, and associated equipment . Published by the Electronic Components Industry Association (ECIA), this standard ensures that hardware from different manufacturers can be seamlessly integrated into a single enclosure.
