注意事项
This document aims to provide simple and distinctive guideli nes for hardware installation.
本文档用于为设备硬件安装提供简明快捷的操作指导。
This document does not describe operations for the pre-delivery installation. Instead, this document
describers only the operations for on-site installation.
本文档对于出厂前已完成的安装操作不进行介绍，仅对现场安装涉及的操作进行介绍。
Electrostatic Discharge 静电
Before touching the device, or holding the boards and IC
chips, wear the anti-static gloves or anti-static wrist strap
to prevent the electrostatic discharge of the human body
from damaging the sensitive components. Ensure that
the other end of the anti-static wrist strap is well
grounded.
在接触设备，手拿插板、单板、IC芯片等之前，为防止人
体静电损坏敏感元器件，必须佩戴防静电手套或者防静电
手腕，并将防静电手腕的另一端良好接地。
Bundling Cables 绑扎线缆
The distance between cable ties or fiber binding straps inside the cabinet should be within 250 mm. (For
subscriber cable, the distance is 200 mm. )
在机柜内部，线扣 / 光 纤绑扎带的绑扎间隔不超过250mm。（用户电缆在机柜内线扣的绑扎间隔不超过
200mm。）
The distance between cable ties for all cables and corrugated pipes outside the cabinet is determined
according to the distance between two horizontal beams. For the cabling trough without beams, bundle
the cables with the distance not exceeding 250 mm between cable ties.
在机柜外部，所有线缆和波纹管的线扣绑扎距离以两横梁之间的间距为准，没有横梁的走线槽按照不超
过250mm的间距绑扎。
Checking Before Installation 安装前检查
Before starting installation, you should make the equipment room, power supply, ground wire, optical
cables, and other facilities in the equipment ready. When these installation conditions are confirmed, the
installation may begin according to the pre-designed layouts.For detailed requirements and related
index, refer to Installation Reference.
在设备安装之前，要求检查机房、机柜、电源、地线、光缆以及配套设施。确定施工条件具备后，按照
工程设计文件进行施工。具体的设备运行要求和相关指标请参见《安装参考》。
