Extreme Networks Consolidated Hardware Guide 2-21
Evaluating and Meeting Cable Requirements
Radio Frequency Interference
If you use unshielded twisted pair (UTP) cabling in an installation, take precautions to
avoid radio frequency (RF) interference. RF interference can cause degradation of signal
quality, and, in an Ethernet network environment, can cause excessive collisions, loss of
link status, or other physical layer problems that can lead to poor performance or loss
of communication.
To prevent RF interference, avoid the following devices or situations:
• Attaching UTP cable to AC power cords
• Routing UTP cable near antennas, such as a Ham radio antenna
• Routing UTP cable near equipment that could exhibit RF interference, such as:
— ARC welding equipment
— Electrical motors that contain coils
— Air conditioner units
— Electrical transformers
In areas or applications where these situations cannot be avoided, use fiber optic
cabling or shielded twisted pair cabling (STP).
Note: Because harmonics can appear on the neutral line of a typical three-phase
power circuit, Extreme Networks recommends using a harmonics meter in new
installations.
