　　二 機柜內(nèi)設備的安裝布局及要求 機柜內(nèi)設備的安裝布局1、 機柜由上到下主要分為四個區(qū)域：交流分配單元、配線架、有源設備、光纜終端盒。

　　Installation layout and requirements of equipment in the second cabinet: 1. The cabinet is mainly divided into four areas from top to bottom: AC distribution unit, distribution frame, active equipment, and optical cable terminal box.

　　2、 交流配電單元從性的要求放在機柜的上端。3、 語音及網(wǎng)絡配線架安裝在易于操作的位置，放在交流配電單元的下面。4、 配線架往下為有源設備區(qū)：差不多的設備根據(jù)功能及線纜連接需要安排位置，比如交換機、路由器，光端機，網(wǎng)橋，三者是一一連接的，為了防止信號線的交叉及功能區(qū)域的易于維護，的排列順序從下往上是光端機->網(wǎng)橋->路由器->交換機。大的設備安裝在機柜下部，并且使用機柜托盤承重。光纖收發(fā)器由于體積小，數(shù)量多，無法在機柜里面固定安裝，也放在托盤上安裝。5、 層放光纜終端盒，也放在托盤上安裝。

　　2. The communication distribution unit is placed at the top of the cabinet for safety requirements. 3. The voice and network distribution frame is installed in an easy to operate location, under the AC distribution unit. 4. The active equipment area is located below the distribution frame: similar devices are arranged according to their functions and cable connections, such as switches, routers, optical transceivers, and bridges, which are connected one by one. In order to prevent signal line crossing and facilitate maintenance of functional areas, the best arrangement order from bottom to top is optical transceivers ->bridges ->routers ->switches. Large equipment is installed at the bottom of the cabinet and supported by cabinet trays. Due to their small size and large quantity, fiber optic transceivers cannot be fixedly installed in cabinets and are also installed on trays. 5. The bottom layer is equipped with fiber optic cable terminal boxes, which are also installed on trays.
