Choose a cabinet that is compatible with all servers, and it should meet or exceed the third class bracket standard of all OEM manufacturers. If you want to install tower or desktop equipment, sliding frames and accessories are required. Because the device contains network cable, telecommunication cable and power cable, it is necessary to purchase hook and loop belt or toothed belt to effectively fix the cable in the cabinet orderly. If the cabinet is equipped with a cable handling module, so that the cable can be directly fixed in the straight device rail, it can't be better. In any case, there should be enough fixed rings (to maintain cables) on the upper wall and side wall inside the cabinet, and the cabinet bottom plate can also be lifted up for wiring below.
If the selected network cabinet is not suitable, after installing the valuable part of the device server into the cabinet, you will find that there is little space left in the cabinet. On the contrary, if you follow the order below, you will be able to select cabinets that match your device priorities (including safety, durability, compatibility and ease of handling) without exceeding your budget.
The first consideration should be safety. It equipment that fulfills crucial mission is put into the cabinet that can be locked, can let network administrator feel more relaxed, also restricted the number that can open cabinet so.
Next, list all the equipment installed in the cabinet and their intact measurement data: height, length, width and weight.
The total height of these devices will determine how many devices can be installed in the cabinet. Obviously, a high cabinet can hold more equipment and save space. Of course, it's not a good idea to use the height of the cabinet as much as possible. There's a lot of room in the back of the cabinet to use. This is the reason for measuring the depth of the cabinet. Select a deeper cabinet, can put two sets of equipment back-to-back, so as to install more equipment. By using the above method, two rows of equipment can be installed in the cabinet, one from the front door and the other from the back door. The cabinet shall be equipped with adjustable straight rail frame, which can be installed with equipment of different depths, so that the cabinet can adhere to small depth according to the depth of the equipment.
After accounting for cabinet space (in "U" or 1.75 inches), consider the size of the room. You won't be happy to see that you're going to have to put some more devices in soon after you've packed the cabinet. Once you buy the cabinet and install it, these extra devices often appear. Therefore, as a basic principle, the cabinet height should be increased by 20% to 30% in case of system expansion. These spaces also improve the ventilation of the equipment.
The equipment with bracket does not need to consider the width, because it is planned according to the width of the cabinet. However, the width of servers and other peripherals that cannot be installed can not be ignored. Because the total weight of the equipment is often not light, it is necessary to choose a cabinet that can hold about 1500 pounds, that is to say, it is necessary to choose a cabinet with good stress structure and firm structure. In the cabinet, the equipment component determines whether the selected sliding frame is standard or weighted, and also determines the selection of other accessories.
The above is to imitate Rittal cabinet purchase precautions, hope to help you, thank you for reading!
