Console Port Setup
E-Series Routers

Connecting Directly to the E-Series Router
When you connect a console directly to the system, use a cable
appropriate for your terminal connector. The cable must have a female
DB-9 connector to attach to the RS-232 port on the system.
The console port is considered a data terminal equipment interface
(DTE). Direct connection to a terminal or PC (which also have DTE
interfaces) requires a crossover cable.
To connect a console directly to the system:
1 Connect the female DB-9 connector to the RS-232 port on the
system’s SRP I/O module. See
Figure 8-1 .
Figure 8-1 E-series routers management ports
2
Connect the crossover adapter connector to your PC’s serial port.
3 Power up the system.
When you power up the system, the CLI appears on your console’s
screen. The system is now in User Exec mode, and you can begin
configuration. For more information on using the CLI and
configuring the system, see the
E-Series System Basics Configuration
Guide .
