1, aluminum plug-in box-cabinet types: If you want to buy to put switches, routers, etc., buy network cabinets, this cabinet alignment groove to do very well. If it is bought to place the server, buy server-type cabinets, this cabinet will be better in comparison to the cooling effect.
2, the first let us know a cabinet a very important international specification: U. 1U = 1.75 inches. There are generally 32U high 42U high. The height of the servers and networking products are also indicated by U. So before you buy, you have to make sure that you have a good idea of what you are looking for. So before you buy, you have to calculate how much space you have in the server room, below, aluminum extrusion box manufacturers list all the equipment to be installed in the cabinet and their intact measurement data: height, length, width, component. The total height of these devices will ultimately resolve how many devices can be installed into the cabinet. Obviously, high cabinets can fit into more equipment, and more space-saving.
Look at the material.
Look at the steel plate, steel plate must be thick, compared to three, you use your fingers to knock, you can feel which thick which thin. And the cabinet internal bracket to be coarse, due to accept a heavier pressure, do not underestimate which switch what ah, a dozen together, are a few heavy under the.
Look at the paint, a qualified cabinet, all the steel needs to be painted, and the paint must be uniform, so that only then outstanding anti-rust, dustproof.
The actual glass, the glass must be thick, but also pay attention to the glass surrounding whether there are cracks, if there are cracks, it means that there are hidden problems, as well as to pay attention to whether to tie the hands.
The first thing that you need to do is to get the right kind of equipment to make sure that you have the right kind of equipment to use. If the cabinet comes with a cable handling module that allows the cables to be fixed directly to the straight rails, then it's even better. In either case, the top and side walls inside the cabinet should have sufficient retaining rings (to maintain the cables), or by lifting the cabinet floor up to allow the cables to run underneath. There should also be a sufficient amount of screws, nuts, etc. to hold the rack in place. Do not bring the expense of lack of accessories due to future expansion.
Look at the utility.
The earliest consideration should be security. The IT equipment to perform critical missions into a lockable cabinet will make the network operator feel relaxed, which also constrains the number of people who can open the cabinet.
Look at the heat, estimate how much heat your equipment, generally speaking, the top of the cabinet have two to four electric fans, electric fans are more than good friends. Side wall fan should be installed in the cabinet wall, due to the equipment rear most of the heat occurs. Generally speaking, the large capacity of the cabinet cooling effect will be a little better.
Look at the structure layout, in general, the baffle to be more, and has a heat dissipation hole, some used to fix the cable tin to wrap, in case of damage to the cable.
Universal feet, although the cabinet, in general, put good, will not move it report, but occasionally always move it, this time, it is useful, now many cabinets are wheel feet, to pick the universal feet.
