use a rollover cable to connect to the asynchronous serial console and auxiliary ports. you can identify a rollover cable by comparing the two modular ends of the cable. hold the cables side-by-side, with the tab at the back. the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (see figure 3-51.) if your cable came from cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8,2 and 7,3 and 6,and 4 and 5).
