Ethernet Connector Signals - Cisco 7000 Series Hardware Installation And Maintenance Manual

Ethernet Connector Signals

Most Ethernet transceivers require an attachment unit interface (AUI) or transceiver cable to connect
an Ethernet transceiver to the EIP Ethernet ports. Some unshielded twisted-pair (10BaseT)
transceivers are compact enough to connect directly to the EIP ports without impeding other
connections. For descriptions of Ethernet transceivers, connectors, and cables, refer to the section
"Ethernet Connection Equipment" in the chapter "Preparing for Installation."
Table A-3 lists the signals for the 15-pin Ethernet connector used on the EIP.
