Install the grounding cable before installing the switch in the rack.
为了防止机箱安装到机柜后无法安装接地线，请先将接地线安装到交换机侧面的接地点上。
The installation positions of the accessories in the following figure are for illustration only.
Determine installation positions for the accessories based on the installation requirement.
以下图中附件的安装位置仅供参考，请根据实际安装场景的需要选择合适的安装位置。
The device provides multiple installation positions for chassis rails on two sides. Determine the
installation position for the chassis rails based on the rack depth. Ensure that slide rails can reach
out of chassis rails after their installation.
设备侧面板提供了多个滑道导轨安装位，用户可根据机柜的深度，调整滑道导轨的安装位置；为保
证设备安装后的稳定性，当滑道与滑道导轨安装完成后，请确保滑道的头部露出滑道导轨。
If the rack depth is in the range of 692 to 854 mm (27.24 to 33.62 in), use the short chassis rails
and long slide rails provided with the switch for installation.
If the rack depth is in the range of 401 to 692 mm (15.79 to 27.24 in), purchase long chassis rails
and short slide rails yourself for installation. You need to install the long chassis rails as follows
based on the rack depth:
Not reaching out or reaching out of the chassis for a rack with a depth in the range of
499 to 565 mm (19.65 to 22.24 in).
Not reaching out of the chassis for a rack with the depth in the range of 401 to 499
mm (19.65 to 19.61 in).
Reaching out of the chassis for a rack with the depth in the range of 565 to 692 mm
(22.24 to 27.24 in).
如果机柜前后方孔条间距在692～854mm范围内，请使用标配的长滑道短导轨配合安装。
如果机柜前后方孔条间距在401～692mm范围内，请使用选配的短滑道长导轨配合安装。因短滑道
长导轨有正装（导轨不会超出设备）和反装（导轨会超出设备）之分，当机柜前后方孔条间距在
499～565mm范围内，长导轨正装和反装都可以；当机柜前后方孔条间距在401～499mm范围内，
请使用长导轨正装方式安装；当机柜前后方孔条间距在565～692mm范围内，请使用长导轨反装方
式安装。
The installation procedure is the same for using long and short chassis rails. The following
procedure uses the short chassis rails as an example.
采用长滑道短导轨安装交换机到机柜与采用短滑道长导轨安装交换机到机柜的方式相同，本文以采
用长滑道短导轨安装交换机到机柜为例。
Before installing cage nuts, mark their installation positions on the rack posts.
安装浮动螺母前，建议用户先使用记号笔在机柜方孔条上标注浮动螺母安装位置。

The switch provides a grounding sign at the primary grounding point but not at the auxiliary
grounding point.
交换机主接地点标有接地标识，备用接地点上无接地标识。
The grounding screws provided with the switch are applicable to both the primary and auxiliary
grounding points.
交换机随机附带的接地螺钉同时适用于主接地点和备用接地点。

The switch can provide airflow from the power module side to the port side, or from the port side to
the power module side, depending on the fan trays installed.
交换机采用前后风道设计，通过配置不同的风扇模块，可提供“电源侧到端口侧”和“端口侧到电源
侧”两种通风走向，满足不同环境下的散热要求。

The LSWM1FANSA fan tray blows air from the power module side to the port side, and the color of
the handle is blue. The LSWM1FANSAB fan tray draws air from the port side to power module side,
and the color of the handle is red.
LSWM1FANSA为吹风风扇，风向为电源侧进风，端口侧出风，风扇把手为蓝色；
LSWM1FANSAB为抽风风扇，风向为端口侧进风，电源侧出风，风扇把手为红色。
Before installing a fan tray, make sure the airflow direction marked on the fan tray meets the ventilation
requirement of the installation site.
安装风扇模块前，请根据风扇模块的风向指示，确认流方向和安装环境的通风要求一致。
Make sure the "TOP" mark stays on top when you install the fan tray.
安装风扇模块时，请确保“TOP”丝印朝上。

Before connecting the power cord, connect the grounding cable and make sure the switch is
reliably grounded.
在连接电源线前，需先连接保护地线，保证交换机正确接地。
Connect the power cord to the switch first and then to the power source to avoid bodily injury.
连接电源线时，请先完成电源线与交换机侧的连接，再进行电源线与供电系统的连接，以免造成人身伤
害。

The switch comes with the five fan tray slots empty. Install five fan trays of the same model for the switch.
交换机出厂时5个风扇插槽均为空，用户需安装5个相同型号的风扇模块。
Make sure each slot has a module or a filler panel installed when the switch is operating.
交换机运行过程中，必须确保所有可插拔模块插槽不能为空，请务必安装相应的模块或假面板。
Do not remove multiple fan trays at a time. You can remove another fan tray only after you finish
replacing one fan tray. Make sure you finish replacing a fan tray within 3 minutes.
更换风扇模块过程中禁止同时拔出多个风扇模块，应按照拔出一个立即更换一个的方式进行，且单个
风扇模块的更换时间不要超过3分钟。
!
Install a filler panel in the power module slot immediately when the slot is empty. The filler panel
prevents dust from entering the chassis and ensures good ventilation.
若电源模块插槽没有安装电源模块，请及时安装假面板，防止灰尘进入交换机，同时又保证设备的良
好通风散热。
