Connecting to the AUI Port

The AUI port is typically used to interconnect hubs using a fiber or thick Ethernet backbone, as illustrated in Figure 2-5 and Figure 2-6. It can also be used to interconnect hubs using a variety of media, such as unshielded twisted-pair, depending on the external transceiver you connect to the port.

A common approach is using two MAUs connected by attaching the transmit pair of one MAU to the receive pair of another MAU. As you do this, the integrity of tip-to-tip and ring-to-ring polarity must be maintained.

Since the AUI port is 802.3 10Base5 compatible, you may use it according to those specifications, paying special attention to max- imum distance, number of devices, and termination guidelines.

❖Note: Make sure SQE (Signal Quality Error) is disabled on the MAU when it is attached to the AUI Port. ❖
