## 3.3 Installing the Switch

Precautions

Pay attention to the following:

l Connect the power cords of different colors to the corresponding cable terminals.

l Ensure that the connector of the power cord is properly seated in the power port of the switch. After the power cord is securely inserted into the device, fasten the power cord with

l power cord retention clips.

l Do not place anything on the top of the switch.

l Maintain a minimum clearance of 100 mm (3.94 in.) around the device to ensure proper airflow. Do not stack switches.

l Keep the switch away from high-power radio launch pads, radar launch pads, and high-frequency large-current devices. Take electromagnetic shielding measures to minimize interference when necessary, for example, use shielded interface cables.

l Manage Ethernet cables with a distance of 100 meters (328.08 feet) indoors. Take lightning protection measures if they need to be routed outdoors.
