To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends side-by-side, with the tab at the back. The wire connected to pin 1 on the left plug should be the same color as the wire connected to pin 3 on the right plug. The wire connected to pin 2 on the left plug should be the same color as the wire connected to pin 6 on the right plug.

Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector, which is described in Table B-3and Table B-4. If you did not order a console cable with your switch, you need to provide an RJ-45-to-DB-9 adapter cable to connect the console port of the switch to a console PC. You need to provide an RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see Table B-3and Table B-4.
