Note: If a port is to operate at 100 Mbps, Category 5 cabling must be used. Category 3

cabling does not meet 100 Mbps specifications. For 10 Mbps operation only, Category 3

or Category 5 cabling can be used. Refer to the “100BASE-TX Network” on page 2-3 for

information about 100BASE-TX networks and cabling.
