1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.
Connection Procedure Follow these steps to connect cables to 1000BASE-T RJ-45 twisted-pair copper
ports.
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.
Figure 19: Making Twisted-Pair Connections
2. Attach the other end to an available port on the switch.
Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.
