Airflow direction of the switch 交换机的风向设计
The switch has a front-rear air aisle. It 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

Installing and removing a fan tray 风扇模块的安装与拆卸
The LSWM1FANSA fan tray provides power module-side intake and port-side exhaust airflow, and
its handle is blue. The LSWM1FANSAB fan tray provides port-side intake and power module-side
exhaust airflow, and its 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，确认气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。
The switch comes with the five fan tray slots empty. You must 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 while 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 simultaneously. 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。
