This appendix lists the pinouts for ports on the supervisor engine module and other modules, and for some interface cable connectors that connect modules to the external network. All pins not specifically listed are not connected.
Following is a list of the signal summaries contained in this appendix:
The console port on the supervisor engine module is an EIA/TIA-232, data communications equipment (DCE), DB-25 receptacle. Both data set ready (DSR) and data carrier detect (DCD) are active when the system is running. The Request To Send (RTS) signal tracks the state of the Clear To Send (CTS) input. The console port does not support modem control or hardware flow control. Table D-1 and Table D-2 list the signals used on this port for all types of supervisor engine modules used in the Catalyst 5000.

Fast Ethernet MII Connector Signals
Most Ethernet transceivers require a transceiver cable to connect an Ethernet transceiver to the supervisor engine module and Ethernet switching module Ethernet ports. Some unshielded twisted-pair (10BaseT) transceivers are compact enough to connect directly to the Ethernet module ports without impeding other connections. For descriptions of Ethernet transceivers, connectors, and cables, refer to the section "Setting Up Ethernet Connection Equipment" in the chapter "Installation Overview."
Table D-3 lists the signals for the supervisor engine module 40-pin MII Fast Ethernet connector.
