如(ru)果不(bu)是(shi)(shi)(shi)業內(nei)的(de)(de)(de)(de)人(ren)可(ke)能在第一(yi)次說(shuo)起機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)的(de)(de)(de)(de)時候想(xiang)(xiang)不(bu)起來(lai)服(fu)(fu)務器，這也(ye)對，它只是(shi)(shi)(shi)機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)的(de)(de)(de)(de)一(yi)種類(lei)型。但總的(de)(de)(de)(de)來(lai)說(shuo)機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)是(shi)(shi)(shi)為(wei)了服(fu)(fu)務計算機(ji)(ji)和網絡設(she)備的(de)(de)(de)(de)。它也(ye)并不(bu)像我們想(xiang)(xiang)象的(de)(de)(de)(de)那(nei)(nei)么(me)(me)簡單，雖然(ran)說(shuo)從面表來(lai)看機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)就是(shi)(shi)(shi)一(yi)個裝(zhuang)(zhuang)著IT設(she)備的(de)(de)(de)(de)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)子。小編在之前(qian)說(shuo)過(guo)，對于機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)來(lai)說(shuo)其(qi)核心的(de)(de)(de)(de)部分就是(shi)(shi)(shi)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)子里裝(zhuang)(zhuang)的(de)(de)(de)(de)東西。然(ran)而這可(ke)和裝(zhuang)(zhuang)衣服(fu)(fu)是(shi)(shi)(shi)完全不(bu)同的(de)(de)(de)(de)，不(bu)能按(an)照(zhao)個人(ren)的(de)(de)(de)(de)喜好，它有自己的(de)(de)(de)(de)規矩(ju)，如(ru)果裝(zhuang)(zhuang)錯了，就不(bu)能正常的(de)(de)(de)(de)完成工(gong)作了。可(ke)以說(shuo)，怎么(me)(me)把那(nei)(nei)些IT設(she)備裝(zhuang)(zhuang)進機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)里是(shi)(shi)(shi)一(yi)門藝術(shu)，今天(tian)小編主要帶(dai)著大(da)家看看機(ji)(ji)柜(ju)(ju)(ju)(ju)(ju)(ju)(ju)(ju)布(bu)線的(de)(de)(de)(de)基(ji)本工(gong)藝。

一(yi)般理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)可以分為(wei)三(san)(san)種(zhong)類型(xing)，我們把它(ta)們成為(wei)機柜(ju)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)的(de)三(san)(san)工(gong)藝，即瀑(pu)布(bu)造(zao)型(xing)、逆向(xiang)(xiang)(xiang)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)和正(zheng)向(xiang)(xiang)(xiang)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)。瀑(pu)布(bu)造(zao)型(xing)是(shi)一(yi)種(zhong)比(bi)較古(gu)老的(de)布(bu)線(xian)(xian)(xian)(xian)造(zao)型(xing)，現在(zai)已(yi)經(jing)基本被淘(tao)汰(tai)了。目前使用比(bi)較頻繁的(de)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)方式是(shi)逆向(xiang)(xiang)(xiang)和正(zheng)面兩種(zhong)。逆向(xiang)(xiang)(xiang)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)是(shi)在(zai)配線(xian)(xian)(xian)(xian)架(jia)的(de)模塊端接完(wan)畢后(hou)，并通過測(ce)試后(hou)，再進行(xing)機柜(ju)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)。而正(zheng)向(xiang)(xiang)(xiang)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)是(shi)在(zai)配線(xian)(xian)(xian)(xian)架(jia)端接前進行(xing)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)。它(ta)從機房的(de)進線(xian)(xian)(xian)(xian)口開始，將線(xian)(xian)(xian)(xian)纜(lan)逐段整理(li)(li)(li)(li)，直到配線(xian)(xian)(xian)(xian)架(jia)的(de)模塊處(chu)為(wei)止。在(zai)理(li)(li)(li)(li)線(xian)(xian)(xian)(xian)后(hou)再進行(xing)端接和測(ce)試。

總的(de)來(lai)說(shuo)他(ta)們各有優勢，也都有自己的(de)缺陷。下面我們來(lai)具體看看：

1)逆向理線(xian)(xian)(xian)(xian)的(de)(de)優點(dian)有(you)，理線(xian)(xian)(xian)(xian)在測試(shi)(shi)后，不(bu)會(hui)因某根雙(shuang)絞線(xian)(xian)(xian)(xian)測試(shi)(shi)通不(bu)過而造成(cheng)重新理線(xian)(xian)(xian)(xian);測試(shi)(shi)已(yi)經完(wan)成(cheng)，不(bu)必擔心機(ji)柜后側(ce)的(de)(de)線(xian)(xian)(xian)(xian)纜(lan)長度。缺點(dian)有(you)，由于兩端(duan)(duan)(進線(xian)(xian)(xian)(xian)口和配線(xian)(xian)(xian)(xian)架)已(yi)經固(gu) 定，在機(ji)房內(nei)的(de)(de)某一處必然會(hui)出(chu)現大(da)量(liang)(liang)的(de)(de)亂線(xian)(xian)(xian)(xian)(一般在機(ji)柜的(de)(de)底(di)部);因為線(xian)(xian)(xian)(xian)纜(lan)的(de)(de)兩端(duan)(duan)已(yi)經固(gu)定，線(xian)(xian)(xian)(xian)纜(lan)之間(jian)會(hui)產生(sheng)大(da)量(liang)(liang)的(de)(de)交(jiao)叉，要想理整齊十分費力，而且在兩個固(gu)定端(duan)(duan)之間(jian)必然有(you)一處的(de)(de)雙(shuang)絞線(xian)(xian)(xian)(xian)是散(san)亂的(de)(de)，這(zhe)一處往往在地板下(xia)(下(xia)進線(xian)(xian)(xian)(xian)時(shi))或天(tian)花上(上進線(xian)(xian)(xian)(xian)時(shi))。

2)正向(xiang)理線(xian)(xian)的(de)(de)優點是可以保(bao)證機房內線(xian)(xian)纜(lan)在(zai)每點都整齊(qi)，且不(bu)會出現線(xian)(xian)纜(lan)交叉。而缺點是如果(guo)線(xian)(xian)纜(lan)本身在(zai)穿線(xian)(xian)時已經損壞，則測(ce)試(shi)通不(bu)過會造成重新理線(xian)(xian)。因(yin)此，正向(xiang)理線(xian)(xian)的(de)(de)前提(ti)是對線(xian)(xian)纜(lan)和(he)穿線(xian)(xian)的(de)(de)質量有足夠的(de)(de)把握。

不(bu)(bu)管(guan)怎么(me)說(shuo)虛擬主機機柜(ju)理(li)線(xian)(xian)(xian)是(shi)一個技(ji)術(shu)(shu)活(huo)，而且不(bu)(bu)需技(ji)術(shu)(shu)過硬。所以選擇(ze)哪(na)種方(fang)式(shi)的理(li)線(xian)(xian)(xian)方(fang)式(shi)要(yao)(yao)根據工程師的技(ji)術(shu)(shu)和喜好(hao)來決定。但前提(ti)是(shi)保障(zhang)各(ge)類線(xian)(xian)(xian)路(lu)的通暢，保障(zhang)里面的IT設備(bei)的正常工作。從(cong)這(zhe)(zhe)一點(dian)來看，如果我們選擇(ze)機柜(ju)租用業務(wu)對其服務(wu)商的技(ji)術(shu)(shu)要(yao)(yao)求不(bu)(bu)需要(yao)(yao)高，同時我們也要(yao)(yao)知道，不(bu)(bu)管(guan)是(shi)哪(na)一種理(li)線(xian)(xian)(xian)方(fang)式(shi)都有不(bu)(bu)可(ke)避免的缺陷。這(zhe)(zhe)樣就(jiu)不(bu)(bu)能(neng)避免故障(zhang)的發生，這(zhe)(zhe)又不(bu)(bu)得不(bu)(bu)說(shuo)到服務(wu)上，就(jiu)是(shi)說(shuo)服務(wu)的質量也要(yao)(yao)跟上。
