Installing the ARN

Connecting to the AUI

The AUI interface provides broadband, baseband, fiber, and shielded twisted pair (STP) support, depending on the transceiver and cables you use.

Caution: Connecting the ARN AUI interface directly to the AUI interface on an Ethernet station violates IEEE 802.3 standards. The AUI interface is designed only for connection to a transceiver.

To attach an Ethernet AUI transceiver (drop) cable to the AUI connector on an Ethernet module:

1.Connect an Ethernet AUI drop cable to the interface labeled AUI (Figure 1-5).

The cable must have a 15-position D-SUB receptacle.
