Use RJ45 Connector Jackets

Use RJ45 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.

Prevent 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.
