First step is connecting the Cisco console to our workstation. I chose to use the Console cable plugged into a Prolific Serial-to-USB adapter. While you can plug your adapter into your Windows workstation and connect via Putty I do not recommend it. Even at Windows 7 I have issues with the adapter and I\u2019m not using one of those cheap Chinese knockoffs. Without fail my workstation will eventually BSoD. Lenovo work laptop or Acer personal laptop it doesn\u2019t matter. I prefer to connect to my Ubuntu workstation and use minicom.

\nPlug in your adapter and check “dmesg” to identify your serial device (usually \/dev\/ttyUSB0).
\n
\n$ dmesg |tail\n[ 88.483038] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0\n[ 88.483050] usb 1-3: Product: USB-Serial Controller\n[ 88.483053] usb 1-3: Manufacturer: Prolific Technology Inc.\n[ 89.517987] usbcore: registered new interface driver usbserial\n[ 89.518001] usbcore: registered new interface driver usbserial_generic\n[ 89.518012] usbserial: USB Serial support registered for generic\n[ 89.520965] usbcore: registered new interface driver pl2303\n[ 89.520998] usbserial: USB Serial support registered for pl2303\n[ 89.521033] pl2303 1-3:1.0: pl2303 converter detected\n[ 89.521962] usb 1-3: pl2303 converter now attached to ttyUSB0<\/code><\/pre><\/p>\nThe connection details are as follows:<\/p>\n
