Chapter 5 Preparing Your Site for Installation
Site Planning
To resolve these problems, you need specialized knowledge and equipment, which could consume
substantial time and money. However, you should ensure that you have a properly grounded and shielded
electrical environment, paying special attention to the need for electrical surge suppression.
Table 5-7
lists electrode magnetic compliance standards for the Cisco ASR 1000 Series Routers.
Radio Frequency Interference
When electromagnetic fields act over a long distance, radio frequency interference (RFI) can be
propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more
EMI on the wiring.
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the
plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a
high-quality twisted-pair cable with one ground conductor for each data signal.
Lightning and AC Power Fault Interference
If signal wires exceed recommended cabling distances, or if signal wires pass between buildings, you
should consider the effect that a lightning strike in your vicinity might have on the Cisco 1000 Series
Router.
The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple
enough energy into unshielded conductors to damage or destroy electronic equipment. If you have
previously experienced such problems, you should consult with RFI/EMI experts to ensure that you have
adequate electrical surge suppression and shielding of signal cables in your Cisco 1000 Series Router
operating environment.
