We have a wide range of server racking for mounting and storing electronic and networking equipment that includes 19-inch racks, sub-racks, transit cases and telescopic sides for wall-mounted and free-standing systems.What is 19-inch racking?Commonly used in server rooms and data centres, 19-inch racks are enclosures or mounts for housing computer networking and data equipment infrastructure. Racks can help to ensure that hardware and networking equipment require minimal floor space or shelf installation.The term 19-inch traditionally comes from the width of the front panel of the boxes that are housed in the rack. The height measurement is known as one rack unit or “U” and is standardised in multiples of 1.752 inches or 44.50 mm – in the IT industry a standard rack structure is 42U tall.Computer equipment that is designed to fit in a rack will often be referred to in terms such as rack-mount, rack mountable, subrack, rack-mounted system, server rack or a rack-mount chassis.Types of server racks and cabinetsThe most common types available include:Floor-standing data cabinets – These are normally geared up for cable management and have various cable entry points.
