•
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.
•
If an AC power cord is routed from outdoors for connecting to the device, connect the power
cord first to a power lightning arrester before connecting it to the power receptacle on the
device.
•
If a network cable is routed from outdoors for connecting to an Ethernet port on the firewall,
connect the network cable first to a network port lightning arrester before connecting it to the
port.
IMPORTANT:
No network port lightning arrester or AC power lightning arrester is provided with the device. Prepare
them as required. For the technical specifications and installation instructions for the lightning
protectors, see the documents shipped with them.
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."
Installation tools
No installation tools are provided with the firewall. Prepare them yourself as required.
