Connecting the Cisco ASR 903 Router to the Network
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient
to allow for fan tray removal.
Note
Connecting Console Cables
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.
Note
Connecting to the Serial Port using Microsoft Windows
This procedure shows how to connect to the serial port using Microsoft Windows.
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.
