•
Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
•
Keep the firewall far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors. If part of the network cable of an Ethernet port must
be routed outdoors, connect a lightning arrester to the cable before you plug the cable into the
port.

Lightning protection

To protect the firewall from lightning better, follow these guidelines:
•
Make sure the grounding cable of the chassis is reliably grounded.
•
Make sure the grounding terminal of the AC power receptacle is reliably grounded.
•
Install a lightning arrester at the input end of the power supply to enhance the lightning
protection capability of the power supply.

Power supply

Verify that the power system at the installation site meets the requirements of the power supplies,
including the input method and rated input voltage. For more information, see "Appendix A Chassis
views and technical specifications."
