The console port is a management port used to provide out-of-band access to the router. It is used for the initial configuration of the router, monitoring, and disaster recovery procedures.

To connect to the console port, a rollover cable and a RJ-45 to DB-9 adapter are used to connect a PC. Cisco supplies the necessary adapter to connect to the console port.

The PC or terminal must support VT100 terminal emulation. Terminal emulation software such as HyperTerminal is usually used.

To connect the PC to a router:

1. Configure terminal emulation software on the PC for:
   • The appropriate com port
   • 9600 baud
   • 8 data bits
   • No parity
   • 1 stop bit
   • No flow control
2. Connect the RJ-45 connector of the rollover cable to the router console port.
3. Connect the other end of the rollover cable to the RJ-45 to DB-9 adapter.
4. Attach the female DB-9 adapter to a PC.
