• Capacitive coupling

• Inductive coupling

• Radiative coupling

• Common impedance coupling

• Conductive coupling

To prevent EMI, take the following actions:

• Take measures against interference from the power grid.

• Do not use the router together with the grounding equipment or lightning-prevention equipment of

power equipment, and keep the router far away from them.

• Keep the router far away from high-power radio launchers, radars, and equipment with high

frequency or high current.

• Use electromagnetic shielding when necessary.

Lightning protection

To better protect the router from lightning, do as follows:

• Make sure the grounding cable of the chassis is correctly grounded.

• Make sure the grounding terminal of the AC power receptacle is correctly grounded.

• Install a lightning arrester at the input end of the power supply to enhance the lightning protection

capability of the power supply.

• Install a special lightning arrester at the input end of outdoor signal lines (for example, E1/T1 line)

to which interface modules of the router are connected to enhance the lightning protection

capability.

Rack-mounting

Before mounting the router in a rack, adhere to the following requirements:

• The rack is equipped with a good ventilation system.

• The rack is sturdy enough to support the router and its accessories.

• For heat dissipation and device maintenance, make sure the front and rear of the rack are at least

0.8 m (2.62 ft) away from walls or other devices, and the headroom in the equipment room is no

less than 3 m (9.84 ft).
