Technical Specifications

Note: Refer to the Cable Guide for Routers and BNX Platforms for the proper cables or cable pinouts to use for each interface type.

Ethernet Attachment Unit Interface (AUI)

The ARN Ethernet base module, Ethernet expansion module, and Ethernet/tri-serial expansion modules contain a 10Base-T standard 802.3 AUI DB-15 receptacle with a slide lock.

Note: The AUI is designed only for connection to a transceiver. Connecting the AUI directly to an AUI on an Ethernet station (without a transceiver) violates IEEE 802.3 standards.

Table C-3 shows the pin assignments for the standard 15-pin AUI receptacle on the ARN base or expansion module and identifies its pin locations.
