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.
