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.
Anti-interference Requirements
Anti-interference indicates the electromagnetic and current interference. The following are the anti-interference
requirements:
Take effective measures for the power system to prevent the interference from the electric grid.
Separate the working ground of the network output engine from the grounding device of the power equipment or the
anti-lightning grounding device.
Keep away from the high-frequency large-current devices like high-power radio transmitters and radar transmitters.
Take electromagnetic shielding measures when necessary.
Anti-Lightning Requirements
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.
For improve the anti-lightning effect, users can attach special lightning prevention equipment to the input end of
outdoor signal lines such as telephone line, E1 line and T1 line that connected with the interface modules of
RSR10-02E series.
Checking the Installation
The following requirements must be met whether routers are installed in a cabinet 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. Ruijie
Networks Routers come with cooling fans, and the cooling principle is like: Cool air is drawn in through the ventilation
holes at the four sides of the chassis, and then dissipated through the fans at the bottom of the chassis. Therefore,
leave at least 10 cm space around the ventilation holes. It is recommended install the routers on the standard
19-inch cabinet. If the environment condition is limited, horizontally place the routers on a clean workbench. Air
conditioner is recommended in hot areas.
The cooling systems of the cabinet and the workbench are proper.
The cabinet or workbench is firm enough to support the router and its accessories.
The cabinet and workbench are properly mounted.
