Airflow through the switch 交换机的风向设计
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI
protection.交换机地线的正确连接是交换机防雷、防干扰的重要保障，请使设备随机提供的保护
地线正确接地。
When you install the grounding cable to the switch, make sure the OT terminal does not affect
the installation and removal of interface cards. 连接保护地线到交换机时，请注意OT端子不能防
碍接口模块扩展卡的安装和拆卸。
Using the LSWM1FANSCE fan tray (S5800-56C-EI as
an example)
采用LSWM1FANSCE风扇模块（以S5800-56C-EI为例）
Using the LSWM1FANSCBE fan tray (S5800-56C-EI as
an example)
采用LSWM1FANSCBE风扇模块（以S5800-56C-EI为例）

The LSWM1FANSCE fan tray blows air from the power module side to the port side. Its handle
color is blue. The LSWM1FANSCBE fan tray draws air from the port side to power module side.
Its handle color is red. LSWM1FANSCE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；LSWM1FANSCBE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 fan tray slots empty. For adequate heat dissipation, you must install
two fan trays of the same model for the switch. Do not power on the switch when the switch
does no have any fan trays or has only one fan tray installed. 交换机出厂时两个风扇插槽为
空，为保证设备的正常散热，用户必须安装两个相同型号的风扇模块。否则禁止交换机上电运
行。
If both fan trays fail when the switch is operating, replace them within 2 minutes.交换机运行过
程中，如果两个风扇模块均出现故障，则必须在2分钟内完成故障风扇模块的更换。
If one fan tray fails when the switch is operating and the operating temperature is not higher
than 27°C (80.6°F), replace the fan tray within 24 hours, and keep the failed fan tray in
position before replacing it. If the operating temperature is higher than 27°C (80.6°F), replace
the fan tray immediately.交换机运行过程中，如果一个风扇模块出现故障，则当环境温度不高
于27℃时，必须在24小时内完成故障风扇模块的更换，且更换前 需保持故障风扇模块在位；
当环境温度高于27℃时，请立即进行更换。
Make sure each slot is installed with a module or a filler panel 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。
