The total amount of U-height available in a 42U high server rack is 42 × 1U. This means that the server rack can accommodate a total equipment height of 42 or in server terms 42x 1U high server racks. This is for a fully populated server cabinet and in reality not all the slots are filled and for cooling and air flow purposes space may be left between the servers themselves and other devices in the cabinet such as an uninterruptible power supply or rack mounted fire suppression system. If spaces are left, this can lead front slots being vacant and these should be filled using blanking space to ensure efficient cooling.

42U Server Cabinets 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 than 1.87m. 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.
| U Height | Metres | Centimetres | Millimetres | Feet | Inches |
|---|---|---|---|---|---|
| 42U | 1.87m | 186.69cm | 1866.90mm | 6.13ft | 73.50" |
For referrence 1U=1.75inches or 44.45mm.
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.
