Connectivity Rules

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.

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 specification includes
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 802.3-2002 standards.
