To avoid device damage and bodily injury, use two people to install or remove the fan
tray.
风扇框较高较重，操作时建议另有一人在旁协助，以免损坏设备或者对您的身体造
成伤害。
The fan tray is hot swappable. Follow these guidelines when you replace the fan tray
on an operating switch:
Ensure electrical safety.
Replace a fan tray only when the other fan tray is operating correctly.
To prevent dust from entering the chassis, keep the failed fan tray in position before
the replacement.
When you hot-swap a fan tray, the remaining fan tray automatically increases the fan
rotation speed and makes louder noise. Take protection measures such as wearing
an earmuff or earplug. In addition, make good preparation before hot swapping a fan
tray to minimize the operation time.
风扇框支持热插拔，在设备运行状态下进行风扇框的更换时，需要注意的是：
请注意用电安全；
只有在保证一个风扇框正常运行的情况下，才可以插拔另一个风扇框；
建议在新风扇框到位后再启动更换操作，在此之前请将旧风扇框保留在机框中，避免
灰尘进入设备；
在设备运行状态下插拔风扇框时，设备处于单风扇框工作状态，智能调速风扇会自动
增加转速，可能会造成噪音增大。请做好防护措施（如佩戴降噪耳罩、耳塞等劳保设
施），并事先做好准备工作尽可能缩短操作时间。
Before you install or replace a switching fabric module on an operating switch, first
remove the fan tray. Install the fan tray immediately after you finish installing or
replacing the switching fabric module.
设备上电工作期间，如果您需要添加或更换网板，请先拆卸一个风扇框并完成对应位置
网板的安装或更换操作，然后及时复原该风扇框。待该风扇框工作正常后，才能拆卸另
外一个风扇框，完成对应位置网板的更换。
For good ventilation, purchase and install filler panels in empty switching fabric module
slots.
未安装网板的槽位请选购并安装网板假面板，以免影响设备散热。
Long-time exposure to strong air flow might cause discomfort. To avoid this hazard, do
not stand close to the air outlet vents while the switch is operating. If you must be next
to the switch on the air outlet vent side for an extended period, avoid the air flow or
take other protective measures.

建议您不要在设备运行时长时间停留在设备出风口侧，以免强风引起身体不适。在
设备出风口侧操作设备时，请尽量避开强风，或者做好相应防护。

The high performance LSXM112XFANH fan tray contains four fans and provides a maximum
airflow of 1240 CFM (Cubic Feet per Minute). When the fan tray is operating, ambient air flows
in through the air vents in the MPU and LPU panels, circulates through the switching fabric
module section, and exhausts through the air vents in the fan tray.
