The following procedure uses the S12512X-AF switch as an example to describe fan
tray installation.
如下以风扇框安装到
S12512X-AF
交换机为例，将风扇框安装到其他交
换机的过程和要求与此例类似，不再赘述。
The S12512X-AF switch has two fan tray slots: FAN1 and FAN2. One fan tray is
sufficient for heat dissipation of the switch. As a best practice, install two fan trays on
the switch for redundancy and noise reduction. S12512X-AF
交换机有两个风扇框槽位：
FAN1
和
FAN2
。选配合适的风扇框后，安装一个风扇框即可满足设备散热要求。
