Introduction
This document summarizes the cabling requirements for console and auxiliary (AUX) ports. Cisco routers either have RJ-45-based or DB-25 DCE/DTEconsole and AUX ports. You can connect either a terminal (DTE) or a modem (DCE) to these ports. In either instance, you will need both an RJ-45 cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 connector.
