You can identify a rollover cable by comparing the two modular ends of the cable. (See

Figure C-1.) Holding the cables in your hand, side-by-side, with the tab at the back, the

wire connected to the pin on the outside of the left connector (pin 1) should be the same

color as the pin on the outside of the right connector (pin 8). On Cisco cables, pin 1 is white

on one connector, and pin 8 is white on the other connector.
