Engineers who spend their days designing the best in electronics are often panicked when they are asked to specify a Server Rack. It is really quite a different skill, moving away from their expertise and into a more physical and mechanical world. To make their job easier, we have compiled five simple questions to ask to insure that they are as successful in this selection as they are in their typical day-to-day work.

What is the actual physical size of the rack that is required?
While the specific server or servers' dimensions may be known, it is important to keep in mind several factors. There may need to be at least a few inches on each side for cable flow or management. Also, there needs to be consideration of the size of the room into which the cabinets are being placed. If it has a low ceiling, for example, two shorter enclosures need to be ganged. On the flip side, do not order a 42u enclosure (a typical standard) if a smaller one will do as rack pricing correlates closely to its size.

2. What are the server cooling requirements?
What are the cooling requirements? Each server should have, as a part of its specs, the heat it generates. There are many approaches to cooling from exhaust fans to cool water piped through the cabinet. This determination and the availability of the required solution from the enclosure manufacturer can have a huge impact on the decision process
3.
How much time is available to spend on assembly and installation?
There are, of course, cost impacts on the time required to get the rack and equipment operational. A knock-down rack will have a much lower cost, but then labor will be required to assemble the unit. Simple features such as numbered holes on the mounting rails can speed installation, as can pre-cut holes for fans or other accessories.
What are the accessories that are required?
Sometimes, an extra pair of mounting rails can be needed to ensure secure installation. Exhaust fans, power strips, shelving, internal lighting, and cable management systems are all potential needs that must be considered. There is nothing worse than being ready to activate the Server Rack only to uncover that there are too many electrical outlets required.
Is there a requirement that is unique to the application?
Many manufacturers are happy to build a unit for specific demands. This can include special heights, widths or depths. It can also include special holes or knockouts, provisions for cooling, or even special colors. Check with the potential suppliers to ensure that they can provide a turnkey unit.
Bonus Question: What is the lead time for this Server Rack?
Some manufacturers, such as Bud, have them in stock ready to ship the same day. Others build to order with a lead time of up to 6 weeks. Depending on the schedule and needs, this can be an important decision factor
It is fairly easy to be a Server Rack expert. It involves asking different questions, but with a few simple steps, the application will be a success.
This buying guide will help you:
Are server racks hard to install? No. Most racks come fully assembled and ready to accept IT equipment. Compatible designs, toolless mounting and an extensive line of rack accessories mean easy planning, fast deployment and more efficient maintenance. As long as you have a level floor or surface that is capable of bearing the combined weight of a rack and the equipment inside of it, installing a cabinet is quite simple.
What is a server rack? Server racks are open frames or cabinets designed for mounting, organizing and securing EIA-standard 19-inch width rack-mount IT and A/V equipment such as servers, routers, hubs, switches and audio/video components, regardless of the manufacturer. They also provide cable management and enable optimized airflow for increased operational efficiency and prolonged equipment life.
Features like quick-adjust mounting rails, modular side panels and toolless mounting slots for vertical PDUs and cable managers facilitate installation and configuration. Seamless compatibility with all EIA-standard 19-inch rack equipment ensures trouble-free setup.
Makes your job easier Most server racks have been designed to optimize installation and maintenance, and that philosophy shows in the details that make routine tasks quicker and easier, adding up to big benefits over the workday.
Support diverse applications Many server rack heights, widths, depths and other variations are available, with a wide range of configuration options so support any application.
Deliver efficient cooling Most network racks feature front-to-rear airflow that supports efficient hot-aisle/cold-aisle configurations and exceed server manufacturer requirements to keep equipment operating reliably. Roof and panel fans are also available to optimize cooling efficiency.
Provide organization and security for critical equipment Server racks have sturdy steel frames and locking cabinets to secure and organize up to 3,000 lbs. of 19-inch rack equipment. They provide safe homes for servers, storage, network hardware and all the indispensable devices that keep your network efficient and productive.

When selecting a server rack, there are some key questions that need to be answered.
What size of rack do you need?
The height of a rack and the height of equipment in it is expressed in "rack units" (a rack unit is 1.75 inches, or 44.45mm). The actual height of a 42U rack is therefore 42 x 1.75 = 73.5 inches. A 2U server would occupy two of the available 42 rack units.
Some racks cabinets come pre-assembled and can be rolled through standard 7-ft. (2.13m) commercial doorways. This allows network equipment to be racked, cabled and rolled into place in a server room for easy installation.
Wall-mount racks offer secure organization for standard 19-inch rack equipment and can support depths up to 36 inches in locations with limited floor space. Most include clear acrylic windows that allow you to monitor equipment without unlocking rack doors.
Open-frame, low-profile and vertical-mount racks are also available to accommodate unique network equipment sizes in locations where security is not a priority and space is limited.
Be sure to make an accurate assessment of the amount of rack space you currently need, and allow for future growth as your network expands.
What is the maximum rack depth required?
Rack depth is dictated by the deepest device you want to install. Determine the maximum rack depth required to mount your equipment in a floor-standing or wall-mount rack enclosure cabinet.
See this convenient Rack Advisor Tool to find a rack that can accommodate the depth and weight of a UPS system, servers and switches it powers.
Can the rack handle the weight of your equipment?
A fully populated rack can weigh upwards of 3,000 lbs. Make sure that the capacity of the rack is greater than the total weight of the equipment being mounted.
