EMI

All electromagnetic interference (EMI) sources, from outside or inside of the router and application system,
adversely affect the router in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, follow these guidelines:
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 MSR4000 router from lightning, do as follows:
Make sure the grounding cable of the chassis is well grounded.

 Make sure the grounding terminal of the AC power receptacle is well 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 standard 19-inch 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).
