When adding hubs (repeaters) to your network, please follow the connectivity
rules listed in the manuals for these products. However, note that because
switches break up the path for connected devices into separate collision
domains, you should not include the switch or connected cabling in your
calculations for cascade length involving other devices.

EQUIREMENTS
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 802.3-2005 standards.
