Planning a 6U network cabinet
A 6U cabinet gives you space for a compact switch-and-patch-panel installation, with more flexibility than a 4U enclosure. The key is to plan what will occupy those six rack units before deciding which depth to buy.
Plan the rack layout
Start with your switch, patch panels and any shelves or cable-management accessories. Add their rack-unit requirements, then leave enough room to route and maintain the cables. A little spare space is useful if you expect to add equipment later.
Choose the right cabinet depth
The 6U figure describes rack height, not cabinet depth. A 300mm-deep cabinet can suit shallow equipment; choose a 450mm cabinet where your switch, power plugs or cable routes need more room. Compare the recommended equipment depth and check front and rear clearance before ordering.
Think about access and mounting
Make sure you can open the front door and remove the panels after installation. Check the overall loaded weight and choose wall fixings to suit the surface. Compare the supplied format of each cabinet so you know whether any assembly is required.

6U Data Cabinets: Your Questions Answered
Help with planning six rack units, choosing the right depth, fitting shelves and cabling a compact installation.
How do I work out how many U of cabinet space I need?
Add together the rack space required by everything you intend to mount: patch panels, switches, shelves, horizontal PDUs, cable managers and any other rack-mounted equipment.
Then consider equipment sitting on shelves. The shelf may occupy 1U at its mounting position, but the equipment resting on its platform may extend through that U and require additional clear space above it.
Finally, leave some room for growth if possible. A cabinet calculation that arrives at exactly 12U for a 12U cabinet is mathematically impeccable and operationally rather optimistic.
Does a shelf itself use rack space?
Yes. A rack shelf occupies the rack positions used by its front mounting flange. Our current front-mount shelves are 1U models, although future shelf variants may use more rack space.
There is an important distinction between the rack space occupied by the shelf mounting and the vertical clearance available above its platform. The platform is situated towards the bottom of the shelf's occupied U, so equipment placed on it extends upwards through that same rack space before requiring additional U positions above.
A device approximately 1U high on a 1U shelf therefore does not automatically require 2U in total. Measure upwards from the shelf platform and allow the actual equipment height plus any required ventilation or access clearance.
What is the difference between nominal cabinet depth and usable internal depth?
The nominal cabinet depth describes the overall depth class of the enclosure — for example 300mm, 450mm, 550mm or 600mm.
The usable internal depth is the space available inside the cabinet after allowing for the front door, rear structure and other parts of the enclosure. It is therefore smaller than the nominal depth.
Approximate usable internal depths are 250mm for a 300mm cabinet, 400mm for a 450mm cabinet, 500mm for a 550mm cabinet and 550mm for a 600mm cabinet.
Usable internal depth should not automatically be treated as suitable equipment depth because connectors, cable bends, rail position and front-door clearance also require space.
Do rear plugs, connectors and cable bends need to be included when checking equipment depth?
Very much so.
The chassis depth tells you where the equipment finishes. It doesn’t tell you where the installation finishes.
An IEC plug, RJ45 connector, fibre lead or other rear connection can require significant additional space, and cables need a sensible bend rather than being folded immediately against the rear panel.
This is one reason the recommended equipment depth is deliberately smaller than the available internal depth. A switch that fits perfectly until somebody attempts to connect electricity to it has only passed the first half of the examination.
Where should I position the patch panel and network switch?
A very common arrangement is to put the patch panel immediately above or below the switch.
That keeps patch leads short, makes ports easier to trace and avoids sending twenty-four little Ethernet excursions around the cabinet before they finally reach a switch sitting several U away.
It isn’t mandatory, though. Your layout also needs to account for cable management, equipment depth, ventilation, power connections and where heavier equipment is best placed.
Think of the rack as a complete system rather than a sequence of individually convenient mounting decisions.
How is the cabinet attached to the wall?
The cabinet has four structural keyhole mounting points at the rear.
These mounting points form part of the cabinet structure and are separate from the removable rear cover or rear access plate.
The cabinet should be secured using all appropriate mounting points and fixings suitable for the wall construction and complete installed load.
Will our 200mm front-mount shelves fit these cabinets?
Yes. Our current 200mm front-mount shelves are available in corresponding 10-inch and 19-inch versions for the current cabinet ranges.
The shelves occupy 1U at their mounting position and have a maximum load rating of 15kg.
Equipment placed on the shelf must also fit within the available cabinet depth and vertical clearance.
