Connecting Console Cables - Cisco ASR 903 Quick Start Manual

Connecting Console Cables

Note You cannot use the USB and RS232 console ports at the same time; if you insert the USB cable into the
router, the RS232 port is disabled.
Connecting to the Serial Port using Microsoft Windows
This procedure shows how to connect to the serial port using Microsoft Windows.
Note Install the USB device driver before establishing a physical connection between the router and the PC,
by using the USB Console cable plugged into the USB serial port. Otherwise, the connection will fail.
For more information, see the Installing the Cisco Microsoft Windows USB Device Driver section in the
Cisco ASR 903 and ASR 903U Aggregation Services Router Hardware Installation Guide.
Procedure
Step 1
Connect the end of the console cable with the RJ45 connector to the light blue console port on the router. or Connect a
USB Type A-to-Type A cable to the USB console port as shown in the figure below . If you are using the USB serial port
for the first time on a Windows-based PC, install the USB driver now according to the instructions in the following sections.
You cannot use the USB port and the EIA port concurrently. See the Connecting to the Auxiliary Port section in
Note
the Cisco ASR 903 and ASR 903U Aggregation Services Router Hardware Installation Guide. When the USB
port is used it takes priority over the RJ45 EIA port.
The USB Type A-to-Type A cable is not included with the Cisco ASR 903 Router; it is ordered separately.
Note
Step 2 Connect the end of the cable with the DB-9 connector (or USB Type-A) to the terminal or PC. If your terminal or PC has
a console port that does not accommodate a DB-9 connector, you must provide an appropriate adapter for that port.
Step 3
To communicate with the router, start a terminal emulator application, such as Microsoft Windows HyperTerminal. This
software should be configured with the following parameters:
• 9600 baud
• 8 data bits
• no parity
• 1 stop-bit
