            |   | 13 | === 2.1 Connecting to the switch === | 
          
          
            |   | 14 |  A serial connection can be set up between the switch and a machine using a RJ-45 to RS-232 cable. Surprisingly, a Cisco cable will work for this. Connect the RJ-45 end to the port labeled "Con" on the switch, and the other end to the PC. Next, start a session from a shell with kermit as root: |

            |   | 23 | Fire up the switch. If you see the U-Boot banner, you can stop the boot process so you can copy/burn the images onto flash.  |
