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)布線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)一(yi)(yi)般主要(yao)(yao)有以下(xia)(xia)三種(zhong)(zhong)方(fang)(fang)法：1、正(zheng)向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)：正(zheng)向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)可(ke)以在(zai)機房（主機房的(de)(de)網絡(luo)區或者(zhe)弱(ruo)電(dian)間(jian)(jian)）中自(zi)進(jin)(jin)(jin)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)口至(zhi)配線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架(jia)(jia)之(zhi)間(jian)(jian)全體整齊、平行(xing)(xing)，十(shi)分(fen)美觀。缺點是施(shi)(shi)工人員要(yao)(yao)對于(yu)自(zi)己的(de)(de)施(shi)(shi)工質量(liang)(liang)有著(zhu)充分(fen)的(de)(de)掌(zhang)控，只有在(zai)基本(ben)上不(bu)會從新端(duan)(duan)接(jie)的(de)(de)基礎(chu)上才能進(jin)(jin)(jin)行(xing)(xing)正(zheng)向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)施(shi)(shi)工。2、逆向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)：逆向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)是在(zai)配線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架(jia)(jia)的(de)(de)模(mo)塊端(duan)(duan)接(jie)完，并通(tong)過測(ce)試(shi)后(hou)(hou)(hou)，再進(jin)(jin)(jin)行(xing)(xing)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)。其方(fang)(fang)法是從模(mo)塊開始(shi)向(xiang)(xiang)(xiang)機柜(ju)外理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)，同時橋架(jia)(jia)內也進(jin)(jin)(jin)行(xing)(xing)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)。這樣做的(de)(de)優(you)點是理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)在(zai)測(ce)試(shi)后(hou)(hou)(hou)，不(bu)會因某根(gen)雙絞線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)測(ce)試(shi)通(tong)無(wu)非(fei)而(er)造(zao)成從新理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)，而(er)缺點是因為兩端(duan)(duan)（進(jin)(jin)(jin)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)口以及配線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架(jia)(jia)）已經經固定，在(zai)機房內的(de)(de)某一(yi)(yi)處必(bi)然(ran)會呈現大量(liang)(liang)的(de)(de)亂線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)（一(yi)(yi)般在(zai)機柜(ju)的(de)(de)底部）。3、理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)板(ban)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)：理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)板(ban)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)實際上也是正(zheng)向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)一(yi)(yi)種(zhong)(zhong)，它是正(zheng)向(xiang)(xiang)(xiang)理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)必(bi)備工具，可(ke)以采取纖維板(ban)、層壓板(ban)或者(zhe)木板(ban)在(zai)現場自(zi)制，也可(ke)以在(zai)公司里制作(zuo)后(hou)(hou)(hou)使(shi)用(yong)。理(li)(li)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)板(ban)的(de)(de)制作(zuo)方(fang)(fang)法十(shi)分(fen)簡(jian)單：測(ce)量(liang)(liang)所(suo)(suo)用(yong)雙絞線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)纜(lan)徑，然(ran)后(hou)(hou)(hou)根(gen)據板(ban)的(de)(de)強度選擇孔(kong)(kong)與孔(kong)(kong)之(zhi)間(jian)(jian)的(de)(de)間(jian)(jian)距，在(zai)板(ban)上橫(heng)向(xiang)(xiang)(xiang)劃(hua)五(wu)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)、縱向(xiang)(xiang)(xiang)劃(hua)五(wu)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)后(hou)(hou)(hou)留有寫(xie)編號的(de)(de)空間(jian)(jian)后(hou)(hou)(hou)，確定板(ban)的(de)(de)長(chang)寬尺寸，剪切(qie)或者(zhe)鋸下(xia)(xia)多余部分(fen)后(hou)(hou)(hou)，使(shi)用(yong)手鉆在(zai)劃(hua)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)交(jiao)叉(cha)點上以所(suo)(suo)確的(de)(de)孔(kong)(kong)徑鉆五(wu)個孔(kong)(kong)，用(yong)粗砂紙將所(suo)(suo)有的(de)(de)邊緣倒角后(hou)(hou)(hou)，在(zai)橫(heng)向(xiang)(xiang)(xiang)寫(xie)上（或者(zhe)刻(ke)上）一(yi)(yi)至(zhi)五(wu)的(de)(de)編號，在(zai)縱向(xiang)(xiang)(xiang)寫(xie)上（或者(zhe)刻(ke)上）A-E的(de)(de)編號后(hou)(hou)(hou)即(ji)可(ke)。

三、網絡機柜安裝方法

1、前(qian)期準備(bei)(bei)(bei)：根(gen)據(ju)網(wang)(wang)(wang)(wang)絡拓撲、現有設備(bei)(bei)(bei)情況、用戶數量、用戶組等因(yin)素(su)，勾畫網(wang)(wang)(wang)(wang)絡機(ji)(ji)柜內部(bu)的(de)接線(xian)圖和設備(bei)(bei)(bei)位置圖；并準備(bei)(bei)(bei)好(hao)網(wang)(wang)(wang)(wang)絡跳線(xian)、標簽紙、各(ge)種類型的(de)塑(su)料綁帶(dai)等必(bi)要(yao)材(cai)料。2、組裝(zhuang)(zhuang)機(ji)(ji)柜：首先組裝(zhuang)(zhuang)頂蓋(gai)和底板，然后(hou)(hou)組裝(zhuang)(zhuang)和豎立腳跟(gen)腳輪，然后(hou)(hou)安裝(zhuang)(zhuang)立柱、側梁、風扇和固定擱板。前(qian)后(hou)(hou)側門最終可(ke)以固定，內部(bu)配件可(ke)以根(gen)據(ju)內部(bu)設備(bei)(bei)(bei)放(fang)置時(shi)的(de)情況進(jin)行安裝(zhuang)(zhuang)。3、整(zheng)理(li)機(ji)(ji)柜：網(wang)(wang)(wang)(wang)絡機(ji)(ji)柜組裝(zhuang)(zhuang)好(hao)后(hou)(hou)，進(jin)行組織線(xian)路、固定設備(bei)(bei)(bei)、貼網(wang)(wang)(wang)(wang)線(xian)標簽等整(zheng)理(li)工作。4、調試測試：整(zheng)理(li)完畢后(hou)(hou)，對網(wang)(wang)(wang)(wang)絡機(ji)(ji)柜進(jin)行測試，打開電源，進(jin)行網(wang)(wang)(wang)(wang)絡連通(tong)性測試，確保(bao)正常運行即可(ke)。

四、網絡機柜u是什么意思

購買網(wang)絡機柜的(de)時(shi)候(hou)，經常會聽(ting)到6U、12U、42U等，其實U實際上是(shi)一個高(gao)度單位(wei)，是(shi)unit的(de)縮略(lve)語，詳細的(de)尺(chi)寸由作為業界團體的(de)美國電子工業協會（EIA）提出，1U≈1.75英寸≈4.445厘(li)米，比(bi)如12U的(de)機柜，就是(shi)指(zhi)機柜內實際可用高(gao)度為12U，約53.34cm高(gao)。
