Electromagnetic Interference
All the equipment powered by AC current can propagate electrical energy that can cause electromagnetic
interference (EMI) and possibly affect the operation of other equipment. The typical sources of EMI are
equipment power cords and power service cables from electric utility companies.
Strong EMI can destroy the signal drivers and receivers in the Cisco ASR 1001-X Router and even create
an electrical hazard by causing power surges through power lines into installed equipment. These
problems are rare, but could be catastrophic.
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 3-6 lists electrode magnetic compliance standards for the Cisco ASR 1001-X Router.
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 ASR 1001-X
Router.
