•
Keep the device 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 you must route interface cables outdoors, install
network port lightning protectors.
Lightning protection
Lightning strikes might damage the device when the lightning strike intensity exceeds a certain limit.
To better protect the device from lightning, follow these guidelines:
•
Make sure the grounding cable of the chassis is grounded reliably.
•
Make sure the grounding terminal of the AC power receptacle is grounded reliably.
•
Install a surge protected power strip at the input end of the power supply to enhance the
lightning protection capability of the power supply.
