Low voltage control cabinet, which must meet or exceed the third class bracket standards of all OEM manufacturers. If you want to install tower or desktop devices, sliding frames and installation accessories are necessary. Due to the installation including network cables, telecommunications cables, and power cables, it is necessary to purchase hook and loop straps or toothed straps to effectively secure the cables in an orderly manner inside the cabinet. If the cabinet comes with a cable management module that allows the cables to be directly fixed inside the vertical installation rail, it would be great. In either case, there should be sufficient fixing rings on the upper and side walls inside the cabinet to protect the cables, or the cabinet bottom plate can be lifted up for wiring underneath.
If the selected network chassis cabinet is not suitable, and the valuable part of the installed equipment - the server - is installed in the cabinet, it will be found that there is very little space left in the cabinet. On the contrary, if you follow the inspection sequence below, you can select cabinets that meet your installation priorities (including stability, durability, compatibility, and ease of loading and unloading) without exceeding your budget.
Next, list all devices installed in the cabinet and their complete measurement data: height, length, width, and weight.
The total height of these devices will ultimately determine how many devices can be installed in the cabinet. Obviously, taller cabinets can accommodate more equipment and save more space. Of course, maximizing the height of the cabinet is not a consideration, and there is also a large area at the back of the cabinet that can be utilized. This is why we need to measure the depth of the cabinet. Choosing a deeper cabinet allows for the installation of two sets of equipment back to back, allowing for the installation of more equipment. By using the above method, two rows of equipment can be installed in the cabinet. One row is loaded and unloaded from the front door of the cabinet, and the other row is loaded and unloaded from the back door. The cabinet should have adjustable vertical guide rails that can accommodate equipment of different depths, while maintaining a small depth according to the depth of the equipment.
After calculating the cabinet space (in units of "U" or 1.75 inches), the size of the room also needs to be considered. You don't want to see the cabinets filled up and soon realize that some more equipment needs to be installed. Once you buy and install the cabinet, these extra devices often appear. So, as a basic principle, the cabinet height should be increased by 20% to 30% in preparation for system expansion. These spaces also improve the ventilation conditions of the equipment.
Devices equipped with brackets do not need to consider width, as they are designed according to the width of the cabinet. But for servers and other peripherals that cannot be installed with brackets, the width cannot be ignored. Due to the fact that the total weight of the equipment is often not light, it is necessary to choose a cabinet that can hold approximately 1500 pounds, which means choosing a cabinet with a good load-bearing structure and a sturdy structure. In the cabinet, the weight of the equipment determines whether the sliding frame selected is standard or weighted, and also determines the selection of other accessories.
