A range of rack mount shelves and brackets for use in server racks and cabinets including L-brackets, fixed, telescopic, modem and adjustable shelves. It is important when choosing rack mount shelves to ensure the depth of the shelf is matched to the cabinet depth and allows for cable runs and other clearances you may require in when populating your rack or cabinet.
This is a general guide for selecting shelves for server cabinets and server racks.
Shelf Type
Mounting
Universal
Note
Fixed shelves
Front and rear
No

Matching Shelf and Server Cabinet Depths
Cabinet Type
Range
Depth Note
Floor Standing
VS (Value) / FS (Floor Standing) / Premium (SR)
The usable depth is 130mm less than the overall cabinet depth
Accoustic
AR (Acoustic) / ARM (Mini Acoustic) / Tranquillo (TAR)
The usable depth is 180mm less than the overall depth
Wall Mounted
WM (Wall Mounted)
The usable depth is 100mm less than the external depth
For example for a 600mm deep foor standing cabinet the usable depth is 130mm deeper = 470mm and then you should allow for any further room you require for cables to run down the back of the cabinet.

Many small businesses and especially those working from home, do not have a server room in which to house their server(s) and computer networking devices. Their IT systems are often run from a corner of their office, and this can lead to several issues including risks of accidental cable disconnection and trip hazards, security to prevent unauthorised access, noise pollution and heat generation.
Computer and small server rooms tend to only have one or two server racks to protect from power outages. For these installations, a rackmount UPS if often the preferred solution. There are some factors to consider when planning to install an uninterruptible power supply in a server rack which do not apply to a floor standing tower system.
Server rack densities are increasing and have quadrupled over the last 9 years from 2011 to 2020. From 2.4kW/rack to 8.4kW/rack according to the latest survey by the Uptime Institute. What affect are these increasing demands having on server rack deployment, power protection and cooling system arrangements and what is the primary cause of data centre outages.
A server rack is a frame into which 19inch rackmount servers, storage and associated networking devices are mounted or ‘rack mounted’. The frame may be 2 or 4-pillar in design. Equipment suitable for a server rack is termed ‘rack mount’ or designed for ‘rack mounting’. A server rack with side panels and a front and rear door assembly can be called a server cabinet. The front door may be solid metal, perforated hex mesh or glass. The rear door is typically solid or perforated hex mesh. The doors and side panels do not just make the server cabinet more secure but also assist air flow management. Server racks and cabinets are defined by their height in ‘U’ where 1U=45mm and their width and depth with typical sizes being 600, 800, 1000 and 1200mm.
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.
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.
