Before installing fan trays, make sure the airflow direction of the fan trays meets the ventilation
requirements at the installation site.
在安装风扇模块前，请根据风扇模块的风向标识，确认气流方向和安装环境的通风要求一致。
Before you install a fan tray, install a switching fabric module in the switching fabric
module slot below the target fan tray slot.
请严格按照先安装交换引擎板再安装风扇模块的顺序进行安装。
To install two fan trays, make sure the models of the two fan trays are the same.

When two fan trays are installed, follow these guidelines to replace the fan trays:
1. If one fan tray fails, the switch can operate correctly if you keep the failed fan tray in
position, and immediate replacement is not required. If you want to replace the failed
fan tray, finish the replacement within 3 minutes.
2. If both fan trays fail, replace the fan trays one after another. Make sure the device
does not operate for more than 2 minutes when no fan trays are installed.
Make sure the new fan tray is the same model as the replaced one.
1. 若两个风扇模块中的一个故障，在保证故障风扇在位的情况下，设备可以继续正常运
行，不需要立即更换，如需更换，请用户在
3 分钟内完成风扇模块的更换；
2. 若两个风扇模块同时故障，请逐个进行更换，为防止高温导致的设备宕机，设备在无
风扇模块情况下的工作时间不能超过
2 分钟。

Determine the required number of fan trays based on the number of installed switching
fabric modules. If one switching fabric module is installed, one fan tray is required. If two
switching fabric modules are installed, two fan trays are required.
请根据安装交换引擎板的数量，确认需要风扇模块的数量，安装单交换引擎板时，只可选
购单风扇模块，安装双交换引擎板时，必须选购双风扇模块。
