10BASE-TX Twisted Pair Network

When connecting a 10BASE‐TX segment to one of the fixed RJ45 ports (odd numbered ports 1‐15), ensure that the network meets the Ethernet network requirements of the IEEE 802.3‐2002 standard for 10BASE‐TX. Refer to the Cabling Guide for details.

Note: If a port is to operate at 100 or 1000 Mbps, Category 5 cabling must be used. Category 3 cabling does not meet the 100 or 1000 Mbps specifications. For 10 Mbps operation only, Category 3, Category 4, or Category 5 cabling can be used. Refer to 100BASE-TX Twisted Pair Network (page 2-2) and 1000BASE-T Twisted Pair Gigabit Ethernet Network (page 2-2) for information about 100BASE-TX and 1000BASE-T networks and cabling.
