2.2.3 Anti-static Requirements
The circuitry of the routers is designed with electrostatic protection, but excessive static
electricity may still damage the circuit boards of the routers. The static electricity of the
network connected with the routers comes largely from the following sources:
 Outdoor electric field produced by the high-voltage supply cable, lightning, etc;
 Indoor systems such as the indoor floor and the entire structure.
Therefore, the following should be done to avoid damage from static electricity:
 Proper grounding of the equipment and floor
 Indoor dust prevention
 Proper temperature and humidity

Wear antistatic wrist straps and antistatic lab coat when touching the circuit board
 Put the removed circuit board face up on an antistatic workbench or in an
electromagnetic shielding bag.
 When observing or carrying the detached circuit board, touch the external edge of the
board and avoid touching the parts on the board directly with hand.
2.2.4 Anti-interference Requirements
Anti-interference means the electromagnetic and current interference. Below please find the
anti-interference requirements:
 Effective measures should be taken for the power system to prevent the interference
from the electric grid.
 The working ground of the network output engine should be preferably separated from
the grounding device of the power equipment or the anti-lightning grounding device,
with a large distance.
 Keep away from the high-frequency large-current devices like high-power radio
transmitters and radar transmitters.
 Take electromagnetic measures when necessary.
2.2.5 Anti-lightning Requirements
The network output engine is provided with anti-lighting protection. However, as an electric
device, it is still vulnerable to powerful lightning. Therefore, measures must be taken to
prevent lightning:
 Ensure good contact between the grounding cable of the router and the ground.
 Ensure that the neutral point of the AC power socket is in good contact with the ground.

To enhance the anti-lightning effect of the power supply, a lighting arrester may be
added in front of the input of the power supply.
