    MULTI-RATE ETHERNET EXTENDER 2.3 Connecting the 10/100Base-T Ethernet Interface The unshielded RJ-45 port labeled Ethernet is the Auto-MDIX 10/100Base-T interface. This port is designed to connect directly to a 10/100Base-T network. Figure 4 shows the signal/pin relationships on this interface. You may connect this port to a hub or PC using a straight through or crossover cable that is up to 328 ft long.
