2.1.3 ESD Prevention

By design, the router is ESD preventative; but excessive buildup of static electricity can still damage the card circuitry and even the entire device.

On the communication network connected to the router, static electricity is primarily introduced from the outside electrical fields, such as the outdoor high-voltage power cabling and lightning, and from the inside system, such as indoor environment, floor material and the equipment frame. To avoid damage, ensure that:

The equipment is well connected to earth. The equipment room is dust-proof.

Maintain adequate temperature and humidity.

Wear an ESD-preventive wrist strap and clothes when contacting the circuit board.

Place the removed circuit board upward on the ESD-preventive workbench, or into a static shielded bag.

Hold the circuit board by its edge when observing or moving it, avoiding direct contact with the elements on it.

2.1.4 Electromagnetic Compatibility

All interference sources, from the outside or from the inside of the router/application system, adversely affect the router in the conduction patterns of capacitance coupling, inductance coupling, electromagnetic wave radiation, and common impedance (including grounding system) coupling. To prevent the interference, do the following:

zTake effective measures against interference from the power grid.

zUse an earthing system or lightning protection grounding different from that for the power supply equipment and keep them as far as possible.

zKeep the router far away from strong power wireless launchers, radar launchers and high frequency and high-current equipment.

zUse electromagnetic shielding when necessary.
