Attaching the mounting brackets and chassis rails of rack-mount rail kit B to the switch
(applicable only to an LS-6800-54QF-H3 switch)
挂耳与超短滑道的导轨配合安装（只适用于
LS-6800-54QF-H3
的机型）
Install a mounting bracket (near the power module
side) and a chassis rail (narrow-spacing installation)
挂耳安装到靠近电源侧、超短滑道的导轨正向安装
Install a mounting bracket (near the port side) and
a chassis rail (wide-spacing installation)
挂耳安装到靠近端口侧、超短滑道的导轨反向安装
Attach cage nuts to the rack posts.
安装浮动螺母到机柜方孔条上
Attach slide rails to the rack posts.
安装滑道到机柜
Mounting brackets near the port side
挂耳安装在靠近端口侧
Mount the switch in the rack (two options)
安装交换机到机柜（二选一）
以产品代码为
LS-6800-54QF-H3
的机型为例
Mounting brackets near the power module side
挂耳安装在靠近电源侧
To use rack-mount rail kit A or C for rack-mounting the switch, make sure the front ends of the long
slide rails or slide rails reach out of the chassis rails. To use rack-mount rail kit B for rack-mounting the
switch, make sure the super-short slide rails slide a minimum length of 90 mm (3.54 in) into the
chassis rails.
为保证设备安装后的稳定性，使用长滑道或滑道和配套的导轨安装完成后，请确保长滑道
或滑道的头部露出导轨。使用超短滑道和配套的导轨安装完成后，请确保超短滑道头部进入导轨的最小
深度为
90mm
。
Connect the other end of the grounding
cable to the grounding point on the rack
接地线另一端连接到机柜接地点
Connect the other end of the grounding
cable to the grounding point on the rack

Airflow direction of the switch
交换机的风向设计
Make sure the air inlet and outlet vents are not blocked and the installation site has a good
ventilation system.
请确保交换机的进、出风孔不被遮挡，并将交换机安装在具有良好通风散热系统的环境中。
You can provide airflow for the switch from the port side to the power module side or from the power
module side to the port side by installing different fan trays.
通过配置不同的风扇模块，可提供“端口侧到电源侧”和“电源侧到端口侧”两种气流方向，满足不
同环境下的散热要求。
The LSWM1FANSC and LSPM1FANSA blow air from the power module side to the port side. The
LSWM1FANSCB and LSPM1FANSB draw air from the port side to the power module side.
LSWM1FANSC
和
LSPM1FANSA
为吹风风扇，风向为电源侧进风，端口侧出风；
LSWM1FANSCB
和
LSPM1FANSB
为抽风风扇，风向为端口侧进风，电源侧出风。
