Check the console cable and make sure it is properly connected to the correct console port on the
PRE, and to your equipment at the other end.
Verify that you are using the proper type of cable and adapter. For additional information about
cable pinouts, see the "Connecting a Video Terminal to the PRE Console Port" section on page
To be sure the cable is not defective or broken, replace the cable with another high quality cable if
possible.
Check that your terminal equipment is working properly and configured with the correct settings for
the console port. The default console port settings are:
9600 baud
–
8 data bits
–
1 stop bit
–
No parity
–
No flow control
–
Check the LEDs on the PRE to make sure that it is powered on properly.
If the cable, connections, power, and terminal settings are all acceptable and you still cannot connect
to the console port on the module, you probably need to replace the PRE. Contact the Cisco TAC
for further assistance.
