Console Port Signals and Pinouts
The Cisco ASR 901 router ships with a console cable kit, which contains the cable and adapters to
connect a console terminal (an ASCII terminal or PC running terminal emulation software). The console
cable kit includes the following items:
•
RJ-45-to-RJ-45 rollover cable
•
RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL)
•
RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL)
To connect a modem, you need to order an auxiliary cable.
For console connections, see the
“Console Port Signals and Pinouts” section on page B-3
.
Console Port Signals and Pinouts
Use the thin, flat, RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-9 female DTE adapter (labeled
TERMINAL) to connect the console port to a PC running terminal emulation software.
Figure B-4
shows
how to connect the console port to a PC.
Table B-4
lists the pinouts for the asynchronous serial console
port, the RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-9 female DTE adapter (labeled
