機箱機柜的分類

Classification of chassis and cabinets

　　從機柜的用途分類，不外乎兩種，設備機柜（服務器機柜）和布線機柜（網(wǎng)絡機柜）。

According to the purpose of the cabinet, there are only two types: equipment cabinet (server cabinet) and wiring cabinet (network cabinet).

　　1、設備機柜：

1. Equipment cabinet:

　　通常設備機柜都是選用標準19英寸寬度，列出所有準備裝在機柜內的設備和它們的高、深、重量。重一些的設備盡量放在機柜的下部（可使機柜站立相對穩(wěn)固）這些設備的總高度將決定可以把多少設備裝進機柜。設備和設備之間要留有一定的空隙，這樣有助于設備通風散熱，設備頂部也要留些空隙，以備將來更換風扇和更好的散熱，高的機柜能裝進更多的設備，所以更省地方。設計完需要使用的機柜后還要預留一些備用空間，因為一旦你把機柜買來并安裝完，一些多出的設備往往就出現(xiàn)了。沒有預留系統(tǒng)擴充的備用空間，到時候就該頭痛了。

Usually, equipment cabinets are selected with a standard 19 inch width, listing all the devices to be installed in the cabinet and their height, depth, and weight. Heavier equipment should be placed at the bottom of the cabinet as much as possible (to make the cabinet stand relatively stable). The total height of these devices will determine how many devices can be installed in the cabinet. There should be a certain gap between the equipment to facilitate ventilation and heat dissipation. The top of the equipment should also have some gaps for future fan replacement and better heat dissipation. A higher cabinet can accommodate more equipment, so it saves more space. After designing the cabinets that need to be used, some spare space should also be reserved, because once you buy and install the cabinets, some extra equipment often appears. If there is no reserved spare space for system expansion, it will be a headache.

　　設備機柜要有良好的凈載重強度，一般要求材料要使用冷軋鋼板（熱板或帶鋼應力不夠，載重時間久了會變形），如果設備太重重量，就要提前告知供應商，增加單層承載力；左右側門相對來說可以用薄一些的材料以減輕機柜自重，如果機柜裝好設備后有可能移動或長時間使用腳輪支撐的話，還需要選擇承重腳輪。

The equipment cabinet should have good net load strength, and generally requires the use of cold-rolled steel plates (hot plates or strips with insufficient stress may deform over time). If the equipment is too heavy, the supplier should be informed in advance to increase the single-layer bearing capacity; Relatively speaking, thinner materials can be used for the left and right side doors to reduce the weight of the cabinet. If the cabinet may move or be supported by casters for a long time after installation, load-bearing casters need to be selected.

　　機柜內的設備有很高的散熱要求，所以選擇機柜除了要有頂置風扇外，選擇有通風網(wǎng)孔的前后門。

The equipment inside the cabinet has high heat dissipation requirements, so when choosing a cabinet, in addition to having a top mounted fan, choose front and rear doors with ventilation mesh holes.

　　機柜內的安裝梁應可以方便的前后移動，有高度標志；托板可以方便的上下移動，前后也應有一定的移動空間，便于安裝設備。

The installation beams inside the cabinet should be easy to move back and forth, with height markings; The pallet can be easily moved up and down, and there should also be some space for movement in front and back, making it easy to install equipment.

　　機柜內的電源應該選用機柜的電源分配單元。

The power supply inside the cabinet should be selected from the power distribution unit of the cabinet.

　　機柜內應有一個以上的接地柱。

There should be more than one grounding pole inside the cabinet.

　　機柜表面噴塑不應有劃傷，內部噴塑不能脫落（露出金屬時間長了容易銹蝕）。

The surface of the cabinet should not be scratched by the spray coating, and the internal spray coating should not fall off (exposing the metal for a long time can easily rust).

　　2、布線機柜：

2. Cabling cabinet:

　　相對服務器機柜來說，人們對網(wǎng)絡機柜的要求不是很高，一般要求進線孔要大，有寬大的理線器或理線環(huán)，使用機柜底座的話，底座進線孔也要盡可能的大些。

Compared to server cabinets, people's requirements for network cabinets are not very high. Generally, it is required to have large cable entry holes, wide cable cutters or cable rings. If using a cabinet base, the cable entry holes on the base should also be as large as possible.

　　布線柜放置地點的環(huán)境條件不是很好，機柜要注意防塵，機柜柜體不能有金屬露出，防止銹蝕。

The environmental conditions where the wiring cabinet is placed are not very good. The cabinet should pay attention to dust prevention, and the cabinet body should not have any metal exposed to prevent rust.
