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(wang)絡(luo)機(ji)(ji)(ji)(ji)柜布線(xian)(xian)(xian)(xian)(xian)(xian)一般(ban)主(zhu)要有以下(xia)三種(zhong)方法:1、正向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian):正向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)可以在(zai)(zai)機(ji)(ji)(ji)(ji)房(主(zhu)機(ji)(ji)(ji)(ji)房的(de)(de)網(wang)絡(luo)區或者(zhe)弱電間)中(zhong)自(zi)進(jin)線(xian)(xian)(xian)(xian)(xian)(xian)口至配線(xian)(xian)(xian)(xian)(xian)(xian)架(jia)之(zhi)(zhi)間全(quan)體整(zheng)齊(qi)、平(ping)行(xing),十(shi)分(fen)美(mei)觀。缺點是(shi)施工(gong)人員要對于自(zi)己的(de)(de)施工(gong)質量(liang)有著充分(fen)的(de)(de)掌控,只有在(zai)(zai)基本上(shang)(shang)(shang)(shang)不(bu)會(hui)從新端接的(de)(de)基礎上(shang)(shang)(shang)(shang)才能進(jin)行(xing)正向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)施工(gong)。2、逆(ni)向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian):逆(ni)向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)是(shi)在(zai)(zai)配線(xian)(xian)(xian)(xian)(xian)(xian)架(jia)的(de)(de)模塊(kuai)端接完,并(bing)通過測試(shi)后(hou)(hou)(hou),再進(jin)行(xing)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)。其方法是(shi)從模塊(kuai)開始(shi)向(xiang)(xiang)(xiang)機(ji)(ji)(ji)(ji)柜外理(li)線(xian)(xian)(xian)(xian)(xian)(xian),同(tong)時(shi)橋架(jia)內也進(jin)行(xing)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)。這樣做的(de)(de)優點是(shi)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)在(zai)(zai)測試(shi)后(hou)(hou)(hou),不(bu)會(hui)因(yin)某根(gen)雙(shuang)絞(jiao)線(xian)(xian)(xian)(xian)(xian)(xian)測試(shi)通無(wu)非而(er)造成從新理(li)線(xian)(xian)(xian)(xian)(xian)(xian),而(er)缺點是(shi)因(yin)為兩(liang)端(進(jin)線(xian)(xian)(xian)(xian)(xian)(xian)口以及配線(xian)(xian)(xian)(xian)(xian)(xian)架(jia))已經(jing)(jing)經(jing)(jing)固定(ding),在(zai)(zai)機(ji)(ji)(ji)(ji)房內的(de)(de)某一處必然會(hui)呈現大量(liang)的(de)(de)亂線(xian)(xian)(xian)(xian)(xian)(xian)(一般(ban)在(zai)(zai)機(ji)(ji)(ji)(ji)柜的(de)(de)底部)。3、理(li)線(xian)(xian)(xian)(xian)(xian)(xian)板(ban)理(li)線(xian)(xian)(xian)(xian)(xian)(xian):理(li)線(xian)(xian)(xian)(xian)(xian)(xian)板(ban)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)實(shi)際上(shang)(shang)(shang)(shang)也是(shi)正向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)一種(zhong),它是(shi)正向(xiang)(xiang)(xiang)理(li)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)必備工(gong)具,可以采取纖維(wei)板(ban)、層壓板(ban)或者(zhe)木板(ban)在(zai)(zai)現場自(zi)制,也可以在(zai)(zai)公司里制作(zuo)后(hou)(hou)(hou)使用(yong)。理(li)線(xian)(xian)(xian)(xian)(xian)(xian)板(ban)的(de)(de)制作(zuo)方法十(shi)分(fen)簡單:測量(liang)所用(yong)雙(shuang)絞(jiao)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)纜(lan)徑,然后(hou)(hou)(hou)根(gen)據(ju)板(ban)的(de)(de)強度選擇孔與孔之(zhi)(zhi)間的(de)(de)間距,在(zai)(zai)板(ban)上(shang)(shang)(shang)(shang)橫向(xiang)(xiang)(xiang)劃五(wu)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)、縱向(xiang)(xiang)(xiang)劃五(wu)根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)后(hou)(hou)(hou)留(liu)有寫(xie)(xie)編號(hao)(hao)的(de)(de)空間后(hou)(hou)(hou),確(que)定(ding)板(ban)的(de)(de)長寬尺寸,剪切(qie)或者(zhe)鋸(ju)下(xia)多余部分(fen)后(hou)(hou)(hou),使用(yong)手鉆在(zai)(zai)劃線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)交叉點上(shang)(shang)(shang)(shang)以所確(que)的(de)(de)孔徑鉆五(wu)個孔,用(yong)粗砂(sha)紙將所有的(de)(de)邊(bian)緣倒角后(hou)(hou)(hou),在(zai)(zai)橫向(xiang)(xiang)(xiang)寫(xie)(xie)上(shang)(shang)(shang)(shang)(或者(zhe)刻上(shang)(shang)(shang)(shang))一至五(wu)的(de)(de)編號(hao)(hao),在(zai)(zai)縱向(xiang)(xiang)(xiang)寫(xie)(xie)上(shang)(shang)(shang)(shang)(或者(zhe)刻上(shang)(shang)(shang)(shang))A-E的(de)(de)編號(hao)(hao)后(hou)(hou)(hou)即可。
三、網絡機柜安裝方法
1、前期準(zhun)備(bei):根據網(wang)(wang)絡拓撲、現(xian)有設備(bei)情(qing)況(kuang)、用戶數量(liang)、用戶組(zu)等因素,勾畫網(wang)(wang)絡機(ji)(ji)柜(ju)(ju)內部(bu)(bu)的接線(xian)圖(tu)(tu)和(he)設備(bei)位置(zhi)圖(tu)(tu);并準(zhun)備(bei)好(hao)網(wang)(wang)絡跳(tiao)線(xian)、標簽紙、各種類型的塑料(liao)綁(bang)帶等必要材料(liao)。2、組(zu)裝機(ji)(ji)柜(ju)(ju):首先組(zu)裝頂蓋(gai)和(he)底板(ban)(ban),然后組(zu)裝和(he)豎(shu)立(li)腳跟腳輪(lun),然后安(an)(an)裝立(li)柱、側梁、風(feng)扇和(he)固定(ding)(ding)擱板(ban)(ban)。前后側門最終可(ke)以(yi)(yi)固定(ding)(ding),內部(bu)(bu)配件可(ke)以(yi)(yi)根據內部(bu)(bu)設備(bei)放置(zhi)時的情(qing)況(kuang)進行(xing)安(an)(an)裝。3、整理機(ji)(ji)柜(ju)(ju):網(wang)(wang)絡機(ji)(ji)柜(ju)(ju)組(zu)裝好(hao)后,進行(xing)組(zu)織線(xian)路、固定(ding)(ding)設備(bei)、貼網(wang)(wang)線(xian)標簽等整理工作。4、調(diao)試(shi)測(ce)(ce)試(shi):整理完(wan)畢后,對網(wang)(wang)絡機(ji)(ji)柜(ju)(ju)進行(xing)測(ce)(ce)試(shi),打開電(dian)源(yuan),進行(xing)網(wang)(wang)絡連通(tong)性(xing)測(ce)(ce)試(shi),確保正常(chang)運行(xing)即可(ke)。
四、網絡機柜u是什么意思
購買網絡機柜的(de)(de)時候,經常(chang)會(hui)聽到6U、12U、42U等,其實U實際(ji)上是(shi)一(yi)個高(gao)度(du)單位,是(shi)unit的(de)(de)縮略(lve)語,詳(xiang)細的(de)(de)尺(chi)寸(cun)由作為業界(jie)團體的(de)(de)美國電子(zi)工業協會(hui)(EIA)提(ti)出,1U≈1.75英寸(cun)≈4.445厘米,比如12U的(de)(de)機柜,就是(shi)指機柜內(nei)實際(ji)可(ke)用(yong)高(gao)度(du)為12U,約53.34cm高(gao)。
