    机箱机柜的几个基础知识解答

    发布时间:2023-04-06 来源:/ 浏览量:

    机箱机柜随着计算机与网络技术的发展,服务器、网络通信设备等设备正在向着小化、网络化、机架化的方向发展,机房对济南机箱机柜管理的需求将日益增长。机柜/机架将不再只是用来容纳服务器等设备的容器,不再是it应用中的低值、附属产品。在综合布线领域,机柜正成为其建设中的重要组成部分越来越受到关注。下面来讲讲基础的内容吧。
    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寸标准机箱机柜内设备安装所占高度用一个特殊单位"u"来表示,1u=44.45mm。u是指机柜的内部有效使用空间,也就是能装多少u的19寸标准设备,使用19寸标准机柜的标准设备的面板一般都是按n个u的规格制造,
    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
    接地有信号接地和机壳接大地等情况,设备的信号接地的作用是提供设备部分或全部电路的电平参考平面,理想的接地平面是零电位、零阻抗的物理实体,任何电流通过它的时候都不会产生压降,通常信号接地有一个专用的接地铜排来实现;机壳接大地是为实现设备接地,防止漏电实现对操作人员的保护,另外的一个作用是泄放因静电感应在机壳上的积累电荷,以免电位升高造成放电,以此提高设备的性。
    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.

    网络机柜和服务器机柜的区别
    The difference between network cabinets and server cabinets
    电力机箱机柜和服务器机箱机柜均是19寸标准机柜,服务器机柜是用来安装服务器、显示器、ups等19"标准设备及非19"标准的设备,在机柜的深度、高度、承重等方面均有要求,宽度一般为600mm,深度一般在900mm以上,因内部设备散热量大,前后门均带通风孔;网络机柜主要是存放路由器,交换机,配线架等网络设备及配件,深度一般小于800mm,宽度600和800mm都有,前门一般为透明钢化玻璃门,对散热及环境要求较低。
    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.
    机架和机柜的区别
    Differences between racks and cabinets
    它们都是用来放置19寸设备的,但机架就是敞开式的,前后左右没有门便于相关设备的安装与施工,但防尘性比较差,相对机柜而言,对外部环境要求更高一些。4立柱机架承重能力大于2立柱机架,2立柱机架配件都是悬臂安装,2点固定,4立柱机架配件安装方式同机柜,4点固定,而机柜是封闭的,有利于保护内部设备。
    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.
