42U Rack and Cabinet Guide

When selecting a rack or cabinet there are several factors to consider.

Rack Height

A 42U rack or cabinet can house equipment whose total height when placed into the rack is no more 73.5inches or 186.69cm (18.67m) with 1U=1.75inches or 44.45mm. Care therefore has to be taken when selecting a rack to make sure that there cabinet height is sufficient to house the IT server, networking peripheral or IoT device.

Rack Width

The standard rackmount width is 19inches (482.6mm) and cabinets are typically available in 600mm or 800mm width. Most products will either fit to the front rack pillars using cage nuts onto flanges attached to the rack-mountable device, or slide rails running from the front to the rear pillars or sit on internal shelves or slide-out trays. Room should be left around the rack for adequate air flow and access.

Rack Depth

The depth of cabinet available range from 600-1200mm. Care should be taken when selecting a rack depth to ensure that it is suitably long enough for the equipment to be housed including any necessary space for cables (bend radius) and connection access. How to manage cables is important for any rack size for easy cable identification and to avoid accidental disconnection.

Open or Closed Racks

The majority of server racks and data cabinets supplied are enclosed rather than open frames. An enclosed cabinet with a front and rear door and side panels is more secure and will provide with more efficient airflow management.

If you cannot find the 42U rack or cabinet you need please contact our projects team.

Related FAQs

  • Do server cabinets always need cooling?

    If your cabinets are only partially populated and has perforated ventilation holes in the front and rear, you may not need additional cooling fan kits. Server manufacturers typically recommend a minimum perforation factor for the doors of the cabinets that would be used to house their servers and this is typically from 63% upwards; to allow adequate air flow from front to rear.

  • What is the best cooling method for my server racks?

    Server racks are designed for front air intake and rear cabinet exit. Cool or air conditioned air should be drawn into the front of the rack by fans within the servers themselves or within the server racks and this then exits as warm air out of the rear of the cabinet. In a data hall server racks are typically positioned in rows and the rows positioned so that the fronts face each to optimise cool air and hot air flows. This is a basic for of hot-aisle/cold-aisle containment. The server racks may themselves be within a separate containment known as a hot-aisle/cold-aisle container. For some server racks we can also offer rear cooling doors to help collect the hot exhaust air. The cooling doors fit onto the rear of the cabinets and use chilled water pipes within the rear door. We can also supply additional cabinet fans for extra cooling capacity.

  • Do you supply semi-knock down kits or just completely made-up rack cabinets?

    We can supply either completely assembled cabinets or semi-knock down kits to allow for ease of transportation and logistics on-site. Our logistics team will follow the project plan (previously agreed) to deliver your server racks and enclosures to site and position them. Where the cabinets are supplied as semi-knock down kits, our installations team can assemble these and move into position for you.
