The fan tray is hot swappable. Follow these guidelines when you hot-swap the fan tray:
Ensure electrical safety.
You can remove a fan tray only when a sufficient number of fan trays are operating
correctly on the device. Do not remove multiple fan trays simultaneously. Remove
fan trays one by one and make sure you finish replacing a fan tray within 3 minutes.
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 trays automatically increase the
fan rotation speed and make louder noises. 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。
只有在保证有足够数量的风扇框正常运行的情况下，才可以插拔其中某一个风扇框。
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。
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，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。

The H3C SecPath FAN-120B-2-A16 fan tray contains two fans and provides a maximum
airflow of 240 cubic feet per minute (CFM). The fan tray draws ambient air into the chassis
through the air vents in the supervisor engine module (MPU), service module, and switching
fabric module panels, pulls the air through the chassis, and exhausts the air carrying heat
through the air vents in the fan tray panel.

For good ventilation, purchase and install filler panels in empty fan tray slots.
未安装风扇框的槽位请选购并安装风扇框假面板，以免影响设备散热。
Long-time exposure to strong air flow might cause discomfort. As a best practice,
do not stand close to the air outlet vents when the device is operating. If you must
be next to the device 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。
