For 1000Base-T connections, all four pairs of wires in the cable must be
available for data transmission. See "Note on 1000Base-T Cable Require-
ments" on page B-2 for more information on 1000Base-T cabling.
For 10 Mbps connections to the ports, you can use Category 3, 4, or 5
100-ohm differential unshielded twisted-pair (UTP) or shielded twisted-
pair (STP) cable, as supported by the IEEE 802.3 10Base-T standard.
For 100 Mbps connections to the ports, use Category 5 100-ohm differen-
tial UTP or STP cable only, as supported by the IEEE 802.3u 100Base-TX
standard.
For 1000 Mbps connections, Category 5 or better 100-ohm differential UTP
or STP cable only, as supported by the IEEE 802.3ab 1000Base-T standard;
Category 5e or better is recommended.
