In the electronics/computing industry, system rack enclosures ("racks") are generally shrinking in overall width to 600mm in order to completely fit on one "standard" data center floor tile. Given the customer desire to utilize floor space as efficiently as possible, racks generally are populated with equipment stacking as high as possible. In addition, customers are requiring taller racks in order to drive floor tile density/utilization higher. While this presents several challenges to overcome, one challenge in particular is rack side-to-side tilt/stability. The taller a thin, 600mm rack gets, the less stable it becomes, side-to-side.

    This invention allows for ballast to be bolted in from the top-side of the rack base pan. This, in turn, allows the fulfillment manufacturer to be able to add ballast and, by using thinner ballast plates, each configuration can be customized to add only as much ballast as needed. This results in a more economically efficient solution. Also, with thinner ballast plates, more economical manufacturing techniques (hard-tooling, casting, etc.) can now be considered for fabricating them.

    The invention cleverly has inverted the center section of the base pan to create a well/depression from the top side as shown in Figure 1 below. M8 threaded standoffs are pressed into the lower, horizontal flanges of the well/depression and are used to secure ballast plates.

    The center well/depression allows ballast plates to be easily inserted from the top side into the rack as shown in Figure 2 below. M8 nuts are used to secure the ballast plates in place.

It can be seen that this invention allows for easy installation of a precise number of ballast plates in an area which provides the most effective increase in rack stability. Also, since ballasts can now be installed at the fulfillment manufacturer, there is no longer a need for multiple rack assembly weldments. In this case, only one rack assembly is needed, and the fulfillment manufacturer is allowed to configure as much ballast as needed. From the figure above, it is desirable to make the ballast plates somewhat thin (~1/4" thick) for easier handling and decent granularity in how much weight is added. By making these plates thinner, more economical fabrication techniques (hard-tooling, casting, etc.) can be considered to decr...
