                                  機箱機柜隨著計算機與網絡技術的發展,服務器、網絡通信設備等設備正在向著小化、網絡化、機架化的方向發展,機房對濟南機箱機柜管理的需求將日益增長。機柜/機架將不再只是用來容納服務器等設備的容器,不再是it應用中的低值、附屬產品。在綜合布線領域,機柜正成為其建設中的重要組成部分越來越受到關注。下面來講講基礎的內容吧。
                                  With the development of computer and network technology, servers, network communication equipment, and other equipment are moving towards miniaturization, networking, and rack ization. The demand for Jinan chassis and cabinet management in computer rooms will continue to grow. Cabinets/racks will no longer be just containers used to accommodate devices such as servers, and will no longer be low value, ancillary products in IT applications. In the field of integrated wiring, cabinets are becoming an important component of their construction and are receiving increasing attention. Let's talk about the basic content below.
                                  容量”u”的概念
                                  The concept of capacity "u"
                                  19寸標準機箱機柜內設備安裝所占高度用一個特殊單位"u"來表示,1u=44.45mm。u是指機柜的內部有效使用空間,也就是能裝多少u的19寸標準設備,使用19寸標準機柜的標準設備的面板一般都是按n個u的規格制造,
                                  The height occupied by the installation of equipment in the 19 inch standard chassis cabinet is represented by a special unit "u", where 1u=44.45mm. U refers to the effective internal usage space of the cabinet, which refers to the number of units that can be installed in 19 inch standard equipment. The panels of standard equipment using 19 inch standard cabinets are generally manufactured according to the specifications of n units,
                                  接地的概念
                                  The concept of grounding
                                  接地有信號接地和機殼接大地等情況,設備的信號接地的作用是提供設備部分或全部電路的電平參考平面,理想的接地平面是零電位、零阻抗的物理實體,任何電流通過它的時候都不會產生壓降,通常信號接地有一個專用的接地銅排來實現;機殼接大地是為實現設備接地,防止漏電實現對操作人員的保護,另外的一個作用是泄放因靜電感應在機殼上的積累電荷,以免電位升高造成放電,以此提高設備的性。
                                  Grounding includes signal grounding and case grounding. The function of signal grounding of equipment is to provide the level reference plane of some or all circuits of the equipment. The ideal grounding plane is a physical entity with zero potential and zero impedance. When any current passes through it, there will be no voltage drop. Generally, signal grounding is realized by a special grounding copper bar; The enclosure grounding is to realize the safe grounding of equipment and prevent electric leakage to protect the safety of operators. Another function is to discharge the accumulated charge on the enclosure due to electrostatic induction, so as to avoid the discharge caused by potential rise, so as to improve the safety of equipment.

                                  網絡機柜和服務器機柜的區別
                                  The difference between network cabinets and server cabinets
                                  電力機箱機柜和服務器機箱機柜均是19寸標準機柜,服務器機柜是用來安裝服務器、顯示器、ups等19"標準設備及非19"標準的設備,在機柜的深度、高度、承重等方面均有要求,寬度一般為600mm,深度一般在900mm以上,因內部設備散熱量大,前后門均帶通風孔;網絡機柜主要是存放路由器,交換機,配線架等網絡設備及配件,深度一般小于800mm,寬度600和800mm都有,前門一般為透明鋼化玻璃門,對散熱及環境要求較低。
                                  The power cabinet and server cabinet are both 19 inch standard cabinets. The server cabinet is used to install 19 "standard equipment such as servers, monitors, UPS, and non 19" standard equipment. There are requirements for the depth, height, and load-bearing of the cabinet, with a width of 600mm and a depth of 900mm or more. Due to the large heat dissipation capacity of internal equipment, the front and rear doors are equipped with ventilation holes; The network cabinet is mainly used to store network equipment and accessories such as routers, switches, distribution frames, etc. The depth is generally less than 800mm, and the width is both 600 and 800mm. The front door is usually a transparent tempered glass door, which has low requirements for heat dissipation and environment.
                                  機架和機柜的區別
                                  Differences between racks and cabinets
                                  它們都是用來放置19寸設備的,但機架就是敞開式的,前后左右沒有門便于相關設備的安裝與施工,但防塵性比較差,相對機柜而言,對外部環境要求更高一些。4立柱機架承重能力大于2立柱機架,2立柱機架配件都是懸臂安裝,2點固定,4立柱機架配件安裝方式同機柜,4點固定,而機柜是封閉的,有利于保護內部設備。
                                  They are all used to accommodate 19 inch equipment, but the rack is open and there are no doors in the front, back, left, and right for the installation and construction of related equipment. However, the dust resistance is relatively poor, and compared to the cabinet, it has higher requirements for the external environment. The load-bearing capacity of a 4-pillar rack is greater than that of a 2-pillar rack. The 2-pillar rack accessories are all cantilever mounted and fixed at 2 points. The 4-pillar rack accessories are installed in the same way as the cabinet, fixed at 4 points, while the cabinet is enclosed, which is conducive to protecting internal equipment.
