一、網絡機柜尺寸有哪些

網絡機柜是用來組合安裝面板、插件、插箱、電子元件、器件和機械零件與部件，使其構成一個整體的安裝箱，它由框架和蓋板（門）組成，一般具有長方體的外形，落地放置，其尺寸規格包括寬度、深度和高度三個方面：1、網絡機柜寬度：標準的網絡機柜有600mm寬和800mm寬，兩個尺寸都可以實現19英寸安裝，800寬常用于線纜比較多的情況。2、網絡機柜深度：網絡機柜常用的深度有600mm、800mm、900mm、960mm、1000mm、1100mm、1200mm等多種規格。3、網絡機柜高度：網絡機柜常見的高度從6U到47U，常用的有32U、37U、42U、47U，其中最常用的是42U，2000mm左右。以上是標準網絡機柜的尺寸，還有一些比較特殊的網絡機柜，比如機掛式網絡機柜尺寸的寬度為480mm左右，深度有700mm的也有800mm的，塔式網絡機柜尺寸就是比較固定的，采用19英寸的話，其寬度與深度可以自己制定，定制網絡機柜注意要選擇一個靠譜的網絡機柜品牌廠家。

二、網絡機柜布線方法

網絡(luo)機柜(ju)(ju)布線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)一(yi)般(ban)主(zhu)要(yao)有以(yi)下三種(zhong)方(fang)法(fa)：1、正向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)：正向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)可(ke)以(yi)在(zai)(zai)(zai)機房(fang)（主(zhu)機房(fang)的(de)(de)(de)(de)(de)網絡(luo)區或(huo)(huo)者弱電間(jian)）中自進線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)口至配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架(jia)之間(jian)全體整齊、平行(xing)，十(shi)分(fen)(fen)美觀。缺點是(shi)(shi)施(shi)工(gong)人員要(yao)對于自己的(de)(de)(de)(de)(de)施(shi)工(gong)質量有著充分(fen)(fen)的(de)(de)(de)(de)(de)掌控，只有在(zai)(zai)(zai)基(ji)本上(shang)不會(hui)從新(xin)端接的(de)(de)(de)(de)(de)基(ji)礎上(shang)才能進行(xing)正向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)施(shi)工(gong)。2、逆向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)：逆向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)是(shi)(shi)在(zai)(zai)(zai)配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架(jia)的(de)(de)(de)(de)(de)模塊端接完，并(bing)通過(guo)測試(shi)后(hou)(hou)(hou)(hou)，再進行(xing)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)。其(qi)方(fang)法(fa)是(shi)(shi)從模塊開始向(xiang)機柜(ju)(ju)外理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)，同時橋架(jia)內也(ye)進行(xing)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)。這樣做的(de)(de)(de)(de)(de)優點是(shi)(shi)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)在(zai)(zai)(zai)測試(shi)后(hou)(hou)(hou)(hou)，不會(hui)因某根(gen)雙絞線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)測試(shi)通無非而造成(cheng)從新(xin)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)，而缺點是(shi)(shi)因為(wei)兩端（進線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)口以(yi)及(ji)配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架(jia)）已經(jing)經(jing)固定，在(zai)(zai)(zai)機房(fang)內的(de)(de)(de)(de)(de)某一(yi)處(chu)必然會(hui)呈現大量的(de)(de)(de)(de)(de)亂線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)（一(yi)般(ban)在(zai)(zai)(zai)機柜(ju)(ju)的(de)(de)(de)(de)(de)底部）。3、理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)板理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)：理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)板理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)實(shi)際上(shang)也(ye)是(shi)(shi)正向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)一(yi)種(zhong)，它是(shi)(shi)正向(xiang)理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)必備工(gong)具，可(ke)以(yi)采(cai)取纖維板、層壓板或(huo)(huo)者木板在(zai)(zai)(zai)現場自制(zhi)(zhi)(zhi)，也(ye)可(ke)以(yi)在(zai)(zai)(zai)公司里(li)制(zhi)(zhi)(zhi)作后(hou)(hou)(hou)(hou)使(shi)(shi)用(yong)。理(li)(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)板的(de)(de)(de)(de)(de)制(zhi)(zhi)(zhi)作方(fang)法(fa)十(shi)分(fen)(fen)簡(jian)單(dan)：測量所(suo)用(yong)雙絞線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)纜徑，然后(hou)(hou)(hou)(hou)根(gen)據板的(de)(de)(de)(de)(de)強度選擇孔與孔之間(jian)的(de)(de)(de)(de)(de)間(jian)距，在(zai)(zai)(zai)板上(shang)橫向(xiang)劃(hua)五根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)、縱向(xiang)劃(hua)五根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)后(hou)(hou)(hou)(hou)留有寫編號的(de)(de)(de)(de)(de)空(kong)間(jian)后(hou)(hou)(hou)(hou)，確定板的(de)(de)(de)(de)(de)長寬(kuan)尺寸，剪切或(huo)(huo)者鋸下多(duo)余部分(fen)(fen)后(hou)(hou)(hou)(hou)，使(shi)(shi)用(yong)手鉆在(zai)(zai)(zai)劃(hua)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)交叉點上(shang)以(yi)所(suo)確的(de)(de)(de)(de)(de)孔徑鉆五個孔，用(yong)粗砂(sha)紙(zhi)將所(suo)有的(de)(de)(de)(de)(de)邊緣(yuan)倒角后(hou)(hou)(hou)(hou)，在(zai)(zai)(zai)橫向(xiang)寫上(shang)（或(huo)(huo)者刻上(shang)）一(yi)至五的(de)(de)(de)(de)(de)編號，在(zai)(zai)(zai)縱向(xiang)寫上(shang)（或(huo)(huo)者刻上(shang)）A-E的(de)(de)(de)(de)(de)編號后(hou)(hou)(hou)(hou)即可(ke)。

三、網絡機柜安裝方法

1、前(qian)期準備(bei)(bei)：根據網絡拓撲(pu)、現(xian)有設(she)(she)(she)(she)備(bei)(bei)情(qing)(qing)況、用戶數量、用戶組(zu)等(deng)因(yin)素，勾畫(hua)網絡機柜(ju)內部(bu)的(de)接線(xian)圖和(he)設(she)(she)(she)(she)備(bei)(bei)位(wei)置圖；并準備(bei)(bei)好(hao)網絡跳線(xian)、標簽紙、各種類型的(de)塑料綁帶等(deng)必(bi)要材料。2、組(zu)裝(zhuang)機柜(ju)：首先組(zu)裝(zhuang)頂蓋和(he)底(di)板(ban)，然后(hou)組(zu)裝(zhuang)和(he)豎立(li)腳跟腳輪，然后(hou)安裝(zhuang)立(li)柱、側梁、風扇和(he)固(gu)定擱板(ban)。前(qian)后(hou)側門(men)最終可以固(gu)定，內部(bu)配件可以根據內部(bu)設(she)(she)(she)(she)備(bei)(bei)放置時(shi)的(de)情(qing)(qing)況進(jin)(jin)(jin)行安裝(zhuang)。3、整(zheng)理機柜(ju)：網絡機柜(ju)組(zu)裝(zhuang)好(hao)后(hou)，進(jin)(jin)(jin)行組(zu)織線(xian)路、固(gu)定設(she)(she)(she)(she)備(bei)(bei)、貼網線(xian)標簽等(deng)整(zheng)理工作(zuo)。4、調試(shi)(shi)測(ce)試(shi)(shi)：整(zheng)理完(wan)畢后(hou)，對網絡機柜(ju)進(jin)(jin)(jin)行測(ce)試(shi)(shi)，打(da)開電源(yuan)，進(jin)(jin)(jin)行網絡連(lian)通性測(ce)試(shi)(shi)，確保正常運行即可。

四、網絡機柜u是什么意思

購買網絡機柜(ju)(ju)的時(shi)候，經(jing)常(chang)會聽(ting)到6U、12U、42U等，其實U實際(ji)上是一個高度單(dan)位，是unit的縮略語，詳細的尺寸(cun)由作為業界(jie)團體的美國(guo)電子工業協會（EIA）提出(chu)，1U≈1.75英寸(cun)≈4.445厘(li)米，比如12U的機柜(ju)(ju)，就(jiu)是指機柜(ju)(ju)內實際(ji)可用高度為12U，約53.34cm高。
