The rack is only used for integrated wiring, installing distribution frames, and cable management frames, to realize the management of cables and optical cable wiring systems. The width of the rack is usually the standard 19 inches, but the depth is greatly reduced, thereby reducing the footprint and saving costs.
The cabinet is used in the fields of heat distribution, network equipment, communication equipment, and electronic equipment. The cabinet usually adopts a fully enclosed or semi-enclosed structure, which has the advantages of enhancing electromagnetic shielding, weakening equipment working noise, and reducing equipment ground area occupation. Some high-end cabinets It also has an air filter function, which improves the quality of the working environment of precision equipment. Many cabinets have a panel width of 19 inches. Therefore, a 19-inch cabinet is the most common standard cabinet.
Compared with the cabinet, the rack is generally an open structure, unlike the cabinet with a fully enclosed or semi-enclosed structure, so in an environment with relatively poor air cleanliness, the surface of the equipment is more likely to accumulate dust. Therefore, the rack is not suitable for installing expensive network equipment.
Cabinets are generally made of cold-rolled steel plates or alloys to store computers and related control equipment. They can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment in an orderly and neat manner to facilitate future maintenance of equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc.
