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.

如果選擇的網(wǎng)絡(luò)機(jī)箱機(jī)柜不合適，把所安裝設(shè)備中貴重的部分---服務(wù)器裝進(jìn)機(jī)柜后，就會(huì)發(fā)現(xiàn)機(jī)柜的空間所剩無(wú)幾。相反，如果遵循下面的檢查順序，你就能選出既符合你的安裝順序(包括穩(wěn)定性、耐久度、兼容性和是否易于裝卸)，又不會(huì)超出你的預(yù)算的機(jī)柜。

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.

接下來(lái)，列出所有裝在機(jī)柜內(nèi)的設(shè)備和它們完整的測(cè)量數(shù)據(jù)：高、長(zhǎng)、寬、重量。

Next, list all devices installed in the cabinet and their complete measurement data: height, length, width, and weight.

這些設(shè)備的總高度將終決定可以把多少設(shè)備裝進(jìn)機(jī)柜。顯然，高的機(jī)柜能裝進(jìn)更多的設(shè)備，而且更省地方。當(dāng)然盡量利用機(jī)柜的高度不是考慮，機(jī)柜的后部也有很大的地方可以利用。這就是要測(cè)量機(jī)柜深度的原因。選擇較深的機(jī)柜，可以把兩套設(shè)備背靠背地裝進(jìn)去，從而安裝更多的設(shè)備。采用上述方式可在機(jī)柜中裝入兩排設(shè)備，一排從機(jī)柜的前門裝卸，另一排從后門裝卸。機(jī)柜應(yīng)有可調(diào)節(jié)的垂直導(dǎo)軌架，可以裝入不同深度的設(shè)備，同時(shí)使機(jī)柜根據(jù)設(shè)備的深度而保持小深度。

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.

在計(jì)算完了機(jī)柜空間(以“U”或1.75英寸為單位)之后，還要考慮房間的大小。你不會(huì)愿意看到塞滿機(jī)柜后不久就發(fā)現(xiàn)還要再裝進(jìn)一些設(shè)備。一旦你把機(jī)柜買來(lái)并安裝完，這些多出的設(shè)備往往就出現(xiàn)了。所以，作為一條基本原則，機(jī)柜高度要多出百分之二十到百分之三十以備系統(tǒng)擴(kuò)充。這些空間也改善了設(shè)備的通風(fēng)條件。

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.

裝有支架的設(shè)備不需要考慮寬度，因?yàn)樗前礄C(jī)柜的寬度設(shè)計(jì)的。但對(duì)于不能安支架的服務(wù)器及其他外設(shè)，寬度是不能忽視的。由于設(shè)備的總重量往往不輕，所以要選一個(gè)能裝大約1500磅的機(jī)柜，也就是說(shuō)，要選受力結(jié)構(gòu)好的、牢固的機(jī)柜。在機(jī)柜里面，設(shè)備重量決定選擇的滑動(dòng)架是標(biāo)準(zhǔn)的還是加重的，也決定其它一些附件的選擇。

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.
