Hardware Installation and Reference Guide
3.2.3 ESD
The router circuitry is designed with anti-static protection, but excessive static electricity may still damage router circuit
boards. The static electricity of the network connected with the routers comes largely from the following sources:

Outdoor electric field produced by the high-voltage power line and lightning.

Indoor systems such as the indoor floor and the entire structure.
Therefore, the following requirements must be met:

Ensure proper grounding of the device and floor.

Prevent indoor dust.

Maintain proper temperature and humidity.

Wear ESD wrist straps and ESD lab coats when touching a circuit board.

Put the removed circuit board face up on an anti-static workbench or in an electromagnetic shielding bag.

Touch the external edge of the board and avoid touching the parts on the board directly with hands when
observing or carrying the detached circuit board.
3.2.4 Anti-interference
Anti-interference indicates the electromagnetic and current interference. The following are the anti-interference
requirements:

Take effective measures for the power system to prevent interference from the power grid.

Keep the router far away from the grounding or lightning protection devices of power equipment.

Keep the router away from high-power radio stations, radar stations, and high-frequency high-current devices.

Take EMI shielding measures when necessary.
3.2.5 Lightning Protection
Ruijie series routers are provided with anti-lighting protection. However, as an electric device, it is still vulnerable to
powerful lightning. Therefore, the following 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.

Add a lighting arrester in front of the input of the power supply to enhance the anti-lightning effect of the power
supply.
3.2.6 Mounting Place
The following requirements must be met whether routers are installed in a rack or placed on a workbench:

Sufficient spacing is reserved at the air inlets and outlets of the routers for good heat dissipation of the routers.

The rack or workbench is firm enough to support the router and its accessories.

The rack and workbench are properly mounted.
