3.2 CONNECTING THE 10/100BASE-T ETHERNET INTERFACE

The Interconnecting cables shall be acceptable for

external use and shall be rated for the proper applica-

tion with respect to voltage, current, anticipated tem-

CAUTION perature, flammability, and mechanical serviceability.

The RJ-45 ports labeled Ethernet are the Auto-MDIX10/100Base-T inter- face. These ports are designed to connect directly to a 10/100Base-T device or network. Figure 5 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.
