Below is an image that shows how to install a console cable into the FWSM's console port.
The console port is located on the FWSM board itself. Installing the console cable will require a removal of the FWSM from the chassis.
After the console cable is installed into the right most console port, push the FWSM back into the chassis. The console cable will squeeze between the blade and the module above it. The gasket will compresss and the console cable should come out the front of the FWSM just above the blade's faceplate.
