Rack cabinets and accessories

Buying guide

Cabinet size is measured in units (U): one unit is 4.45 centimetres, and you should add spare space to the total height of your equipment for cabling and ventilation. A wall cabinet holds a small office's switch and recorder, while servers need a deeper, floor-standing cabinet. Check the depth separately – it's the dimension people forget most often. Shelves, fans and power strips are sold as separate accessories.
