2.2.3 Lightning Protection
In thunderstorm weather, a sudden strong current may damage the switch. To protect your switch
from lightning strike or strong current, please:
Make sure the switch, rack, installation desktop, and power socket on the wall all are
well-grounded.
Route the switch cables properly.
If you need to route cables outdoors, it is advised to use a lightning arrester.

No matter whether your switch is installed on a rack or desktop, follow the instructions below:
Make sure the rack or desktop be stable and firm enough.
The room must be well-ventilated. Keep at least 10 cm distance between all sides for cooling.
Do not place any heavy or big-size object on the switch.
Keep at least 1.5 cm vertical distance between each switch while installing it on a rack.
