• Verify all the cabling limitations (particularly distance) before powering on the system.
Connecting the Console Port Cables
The router uses RJ-45 port to attach a console terminal. The router has an asynchronous serial (EIA/TIA-232)
RJ-45 console port labeled CON on its front panel. You can connect this port to most types of video terminals
with a console cable kit that is included with your router. The console cable kit contains:
• One RJ-45-to-RJ-45 crossover cable
A crossover cable reverses pin connections from one end to the other. In other words, it connects pin 1 (at
one end) to pin 8 (at the other end), pin 2 to pin 7, pin 3 to pin 6, and so on. You can identify a crossover cable
by comparing the two modular ends of the cable. Hold the cable ends in your hand, side-by-side, with the
tabs at the back. Ensure that the wire connected to the outside (left) pin of the left plug (pin 1) is the same
color as the wire connected to the outside (right) pin of the right plug (pin 8).
The console port is an asynchronous serial ports; devices connected to this ports must be capable of
asynchronous transmission. Baud rates for the RJ-45 console port are 1200, 2400, 4800, 9600, 19200, 38400,
57600, and 115200 bps.
Before connecting to the console interface on the router using a terminal or PC, perform the following steps:
Procedure
Step 1
Before connecting a terminal to the console port, configure the terminal to match the chassis console port as
follows: 9600 baud, 8 data bits, no parity, 1 stop bits (9600 8N1).
Step 2
Connect one end of the RJ-45 cable to the serial RJ-45 console port (CON) .
For information about how to change the default settings to meet the requirements of your terminal
or host, see the
Cisco IOS Terminal Services Configuration Guide
.
Note
Step 3
After you establish normal router operation, you can disconnect the terminal.
Connecting to the Micro USB Console Port
The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin
micro USB Type-B cable. The USB Console supports full speed (12Mbps) operation. The console port does
not support hardware flow control.
