The switch provides a grounding sign at the primary grounding point but not at the
auxiliary grounding point.
交换机主接地点标有接地标识，备用接地点上无接地标识。
The two grounding screws at the primary grounding point are also applicable to the
auxiliary grounding point.
交换机主接地点上的两个接地螺钉同样适用于备用接地点。
Install the grounding cable before installing the switch in the rack.
为了防止机箱安装
到机柜后无法安装接地线，因此请先将接地线安装到交换机的侧面接地点上。
Before installing cage nuts, mark their installation positions on the rack posts.

Airflow direction of the switch
交换机的风向设计
Make sure the air inlet and outlet vents are not blocked and the installation site has a
good ventilation system.
请确保交换机的进、出风孔不被遮挡，并将交换机安装在具有
良好通风散热系统的环境中。
You can provide airflow for the switch from the port side to the power module side or
from the power module side to the port side by installing different fan trays.
通过配置不
同的风扇模块，可提供“端口侧到电源侧”和“电源侧到端口侧”两种气流方向，满足
不同环境下的散热要求。
The LSWM1HFANSC and LSPM1FANSA fan trays blow air from the power module
side to the port side. The LSWM1HFANSCB and LSPM1FANSB fan trays draw air
from the port side to the power module side.
