Routers
Ethernet Connections
This section describes the single-port, dual-port, and six-port Ethernet network processor
modules.
Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX”
are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to
other SELV circuits. Because the BRI circuits are treated like telephone-network voltage,
avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits. (To see
translated versions of this warning, refer to the appendix “Translated Safety Warnings.”)
Note The single-port Ethernet network processor module is not supported on the
Cisco 4500-M and Cisco 4700-M. The six-port Ethernet network processor module is not
supported on the Cisco 4000-M.
Single-Port Ethernet Module Connections
Each single-port Ethernet network processor module has an Ethernet attachment unit
interface (AUI) connector and a 10BaseT connector. (See Figure 4-5.) (Only one connector
on the module can be used at a time.) Use either an IEEE 802.3 AUI or a 10BaseT cable to
make the connection.
Selecting the Media Type
The media type connection, AUI or 10BaseT, is selected by the media-type command.
Enter the media-type command in the router’s configuration file to configure your selection
of AUI or 10BaseT on the desired interface. The syntax of the media-type command is as
follows:
media-type aui
media-type 10baset
