19-inch Server Rack, Server Rack,

How Equipment Mounting is Done for 19-inch Server Rack Enclosures

There are several ways on how mounting is done on a 19-inch server rack enclosures. See the different examples below:

Mounting Through Fastening

When it comes to mounting, the original way on how companies do it is holes were trapped and sealed in with a specific screw thread. Then, when the rack rails become too thin to tap, the threaded inserts are now utilized. There are particular class of equipment that are known in advance, some of its holes can be removed from the mounting rails.

The threaded mounting holes found in racks where the equipment is always changed becomes very problematic because the threads utilized can be damaged. There is also a possibility that the mounting screws can easily break off. Both of the issues can make the mounting hole very unusable. Tapping and sealing the huge number of holes that might never be used can be very costy. Nevertheless, the tapped-hole racks can still be in use. Generally, for the hardware of the server rack that is being rarely changed. The examples that comes with this  includes the network cabling panels, telephone exchanges, broadcast studios and the equipment found in government & military.

The replacement is done with the tapped-hole rack was first replaced by a clearance-hole. This can be in round hole, round unthreaded holes, and versa rail. The holes should be huge enough to accommodate a bolt to be freely installed without the need for binding. After which, the bolts are now being fastened and installed using cage nuts.

In case the nut is being removed or stripped out because a bolt is breaking, the nut can be easily removed and be replaced with a latest one. The production of these type of clearance-hole racks can be less expensive primarily because tapping of the holes is now being removed. In addition to this, they are being replaced with fewer and less expensive cage nuts.

The next innovation when it comes to designing server racks came with square-hole rack. The square-hole racks will accommodate boltless mounting. This is because the rack-mount equipment should only need to be inserted through and the engineers can hook down the server rack into the square hole. The installation and the removal of the hardware attached to the square hole rack of the server rack can be very easy and boltless. Wherein the weight of the installed equipment and small retention clips should be all necessary to be able to hold the equipment in order. In case the server rack is an older equipment meant to be installed in round-hole or tapped hole, these server racks can still be utilized. With the use of cage nuts created for square-hole racks.

Structural support of Server Racks

For everyone’s information, the rack-mountable equipment is used to be traditionally mounted by using bolting or clipping the front panel on to the server rack. In the IT industry, it is very common for the network communications equipment to have several mounting positions. This also includes the table-top and wall-mounting which is very common for other equipment. This also holds true when it comes to rack-mountable equipment. This type of mechanism features L-brackets that should be screwed or bolted on the equipment before installing it in a 19=inch rack.

With the continuous use when it comes to 23-inch racks in the telecommunications industry, the same practice of installation is very common. But the equipment will have 19-inch and 23-inch brackets very available. This enables them to be mounted on the existing racks.

One of the key structural weakness of the front-mounted support is that it has the shear stress when it is installed in mounting rails and the leading edge of the equipment. As the result of this, the 4-post racks became very common to several users. This has the racks that features a mirrored pair of the rear mounting posts.

Since the space indicated between the front and rear mounting posts might have a huge difference between the rack vendors/or the configuration of the racks, it can become very common of the equipment to feature 4-post mounting brackets and have an adjustable rear bracket.

With this in mind, the server racks that comes with the deep pieces of several equipment are often installed utilizing the rails that are bolted to the front and rear the posts. This gives the equipment space allowance so that the four posts can be supported. While also allows it to be easily installed and removed from the place where it is being installed.

Does Mass Customization Has the Possibility to Kill Mass Production?

There are several technologies existing today that makes the mass production very possible. One of which is the new HP’s MultiJet Fusion printers. These printers are primarily made to build and create custom insoles. Now in line with this launch, the superfeet has already announced its first shoe brand tie up and partnership together with Brooks. This can be a signal of a very valid and true beginning of mass customization for companies.

Together with Superfeet’s FitStation powered by power printer made by HP, the brand will release a performance running shoe to the market that is primarily based on an individuals foot scan in 3D.

“The ability to give an individual a personalized shoe based on his or her unique biomechanics is a game changer. It is a compelling offering for the runner who is interested in tip-of-the-spear technology and a totally tuned experience,” said Brooks CEO Jim Weber.

He said that his company has been pursuing this type of technology because the customization of shoes can offer a very advantageous edge in the shoe market.

The scanning system hardware and software can effectively combine the 3D foot scanning together with its very different and dynamic gait analysis and foot pressure measurements. This aim to identify the unique motion path of the runner’s individual body.

Additive Manufacturing or Injection Molding?

Does this mean that it has additive manufacturing? Or is it made from injection molding?

At least it is the DESMA polyurethane injection-molding machine for this brand,

To further illustrate, this type of system uses the 3D foot scans to identify the proper lasts which the shoes are being built around. This is to make sure that each shoe is being tailor fitted according to the specific shape of the runner’s foot. Then, by using a very good combination of the variable PU injection which ahs the direct attach capabilities – the foot pressure being measured together with the movement analysis of the athlete’s or individuals’ runner joints are being successfully combined with their personal preferences. This crates the perfect personalized midsole requirements that has multiple tuned zones.

Most Frequently Asked Questions about NEMA 1 Electronics Enclosure

One of the fastest and quickest ways to be able to identify if an electronic box will certainly meet your company’s needs is to identify its NEMA rating. The rating system is designed to help the companies determine which enclosure should they get for a certain engineering application. The rating will also give the user the vital information about its protective performance – but it is really important to have a firm and full understanding of the NEMA ratings before they companies can choose one.

In this article we will look at the most frequently asked questions about NEMA 1 Electronics Enclosure.

What does NEMA rating mean?

NEMA ratings is an established system of electrical enclosure ratings set by National Electrical Manufacturers Association to help the companies identify different qualities of each electronics enclosure. This rating shows how different types of NEMA ratings can give protection from certain environmental hazards such as dirt, dust, and water ingress. Included in this rating is also the corrosion protection.

For companies or design engineers to learn about what these different NEMA ratings mean, they should check out the official NEMA ratings website and chart to have a full understanding of how the different level of NEMA ratings can give certain protection it indicates. In line with this, make sure that all the guidelines have been read carefully because unlike IP ratings, they do not come with numerical orders that determine the rate of protection each enclosure can give.

What does NEMA 1 mean?

When it comes to varying degrees of protection NEMA enclosure gives, NEMA 1 offers the most basic level of protection. This type of enclosure is used to protect equipment from ingress of small amounts of falling dirt. NEMA 1 also gives protection for employees from having accidental contact because there might be live components inside the enclosure. With this in mind, NEMA 1 electrical box rating provide a good amount of protection from liquid ingress that can come from hose-directed or splashing water.

Where can I use NEMA 1 Electrical Boxes?

Companies use NEMA 1 enclosure in applications where they need the most basic level of protection for their equipment. Basically, almost all types of electronics equipment can be housed inside the NEMA 1 enclosure. For example, you can put in an industrial control panels inside the electrical box or controls to different security systems.

In a typical scenario, you will be able to see NEMA 1 enclosure for engineering applications which does not need protection against hazardous environmental hazards, but they will be needing the most basic level of protection for their equipment.

Is NEMA 1 Electrical Enclosures Applicable for Outdoor Applications?

NEMA 1 electrical boxes are recommended for indoor engineering applications. NEMA 1 can be sufficient in some outdoor environments, but if a company needs a level of protection for their equipment once used outdoors, the best idea is to use the enclosure rating that is primarily designed for outdoor use. Such as NEMA 3, NEMA 4 or even NEMA 6 electronics enclosure.

What is the key difference between NEMA 12 and NEMA 1 electrical enclosure?

NEMA 12 rated electrical boxes offer a much higher degree of protection compare to NEMA 1 enclosure. Keep in mind that NEMA 1 electronics enclosure can only offer so much as long as you need protection for your equipment for any indoor type of application.
