RJ-45 Connector Jackets
Use RJ-45 cable with connector jackets that are flush with the connector or that have connectors with a
no-snag feature.
Using cable with jackets that are wider than the connectors can cause:
•
Connectors that are not properly aligned with the port.
•
Crowded cable installation, which can cause connectors to pop out of the port.

Preventing Radio Frequency Interference (RFI)
If you use 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 situations:
