兩機柜之間的理線

閱覽次數：3154 次  
在信息機房內，時常會出現兩個機柜之間敷設有一束雙絞線的要求，這時如果在兩個配線架上使用相同的配線架進線及出現規則，就可能會出現線束扭轉的現象。要解決這個問題，兩個機柜應分別選用不同的理線表。以下以左側機柜（A配線架）向右側機柜（B配線架）敷設雙絞線
（右進上(shang)(shang)出(chu)）為例，分(fen)A、B、C、D四種(zhong)情況進行分(fen)析（使用(yong)藍、橙、綠、棕、灰五(wu)種(zhong)顏(yan)色分(fen)別標(biao)明最上(shang)(shang)層、次上(shang)(shang)層、中(zhong)層、次下層和最下層）：
   A.、右(you)側(ce)(ce)(ce)機柜(ju)配(pei)線(xian)(xian)(xian)(xian)架與左側(ce)(ce)(ce)機柜(ju)配(pei)線(xian)(xian)(xian)(xian)架同方向(xiang)，且(qie)均為右(you)側(ce)(ce)(ce)進線(xian)(xian)(xian)(xian)（在(zai)(zai)A配(pei)線(xian)(xian)(xian)(xian)架上雙(shuang)絞線(xian)(xian)(xian)(xian)的排列(lie)為1號線(xian)(xian)(xian)(xian)最先出(chu)現，其他線(xian)(xian)(xian)(xian)按順序出(chu)線(xian)(xian)(xian)(xian)，排列(lie)整齊；在(zai)(zai)B配(pei)線(xian)(xian)(xian)(xian)架上仍然是1號線(xian)(xian)(xian)(xian)先出(chu)線(xian)(xian)(xian)(xian)，但(dan)因(yin)它排列(lie)在(zai)(zai)B配(pei)線(xian)(xian)(xian)(xian)架線(xian)(xian)(xian)(xian)束中4號線(xian)(xian)(xian)(xian)的位置，所以每層線(xian)(xian)(xian)(xian)在(zai)(zai)出(chu)線(xian)(xian)(xian)(xian)時(shi)會有交叉，由于(yu)五層線(xian)(xian)(xian)(xian)的交叉位置完全(quan)一致，所以在(zai)(zai)B配(pei)線(xian)(xian)(xian)(xian)架上不會影響美觀。
   B、右側(ce)(ce)機(ji)柜配線架與左(zuo)側(ce)(ce)機(ji)柜配線架同(tong)方向，右側(ce)(ce)機(ji)柜為左(zuo)側(ce)(ce)進線（左(zuo)進上出(chu)）
在(zai)(zai)(zai)A配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架上(shang)雙絞線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)排(pai)列為1號(hao)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)最先(xian)出(chu)(chu)現，其他線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)按順(shun)序出(chu)(chu)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)，排(pai)列整齊；在(zai)(zai)(zai)B配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架上(shang)仍然是(shi)1號(hao)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)先(xian)出(chu)(chu)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)，但因它排(pai)列在(zai)(zai)(zai)B配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)束中4號(hao)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)位(wei)置(zhi)，所以(yi)每層(ceng)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)在(zai)(zai)(zai)出(chu)(chu)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)時會(hui)(hui)有交叉(cha)，由于五層(ceng)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)的(de)交叉(cha)位(wei)置(zhi)完全一致，所以(yi)在(zai)(zai)(zai)B配(pei)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)架上(shang)不會(hui)(hui)影響(xiang)美觀。
  C、右(you)側(ce)機(ji)柜(ju)配(pei)線(xian)架與左側(ce)機(ji)柜(ju)配(pei)線(xian)架反方向，且均(jun)為右(you)側(ce)進(jin)(jin)線(xian)（右(you)進(jin)(jin)上出）
在(zai)(zai)A配線(xian)(xian)架(jia)上雙絞線(xian)(xian)的(de)(de)排列(lie)為1號(hao)線(xian)(xian)最(zui)先出(chu)現，其他線(xian)(xian)按順(shun)序出(chu)線(xian)(xian)，排列(lie)整齊；在(zai)(zai)B配線(xian)(xian)架(jia)上仍然是1號(hao)線(xian)(xian)先出(chu)線(xian)(xian)，但(dan)因它排列(lie)在(zai)(zai)B配線(xian)(xian)架(jia)線(xian)(xian)束(shu)中(zhong)4號(hao)線(xian)(xian)的(de)(de)位置，所以每層(ceng)線(xian)(xian)在(zai)(zai)出(chu)線(xian)(xian)時(shi)會(hui)有交叉(cha)(cha)，由(you)于(yu)五(wu)層(ceng)線(xian)(xian)的(de)(de)交叉(cha)(cha)位置完全一致，所以在(zai)(zai)B配線(xian)(xian)架(jia)上不會(hui)影響美觀。
D、右側機柜(ju)配(pei)線架與左(zuo)側機柜(ju)配(pei)線架反方向，右側機柜(ju)為(wei)左(zuo)側進線（左(zuo)進上出(chu)）
在A配線架上(shang)雙絞線的排列為(wei)1號(hao)線最(zui)先出(chu)(chu)現(xian)，其(qi)他線按順(shun)序出(chu)(chu)線，排列整齊；在B配線架上(shang)為(wei)24號(hao)線先出(chu)(chu)線，改為(wei)了(le)下出(chu)(chu)線方(fang)式，由(you)于最(zui)上(shang)層的線全部(bu)覆(fu)蓋(gai)在所(suo)有的線上(shang)，保持了(le)一(yi)層完全平整的斜(xie)線，所(suo)以在B配線架上(shang)依舊美觀(guan)。
    由上述這(zhe)四種機柜配線(xian)架(jia)(jia)擺放方(fang)法和進(jin)線(xian)方(fang)向的(de)(de)理線(xian)方(fang)式組合，利用類推出其他組合的(de)(de)理線(xian)方(fang)式。采用這(zhe)樣的(de)(de)方(fang)法，可以確(que)保整束(shu)雙絞(jiao)線(xian)不會在敷設過程中(zhong)翻轉，僅需要改(gai)變(bian)第2個配線(xian)架(jia)(jia)的(de)(de)出線(xian)方(fang)式就(jiu)可以解決問題。
