You can identify a rollover cable by comparing the two ends of the cable. Holding 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 B-5
.) If your
cable was purchased from Cisco Systems, 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.)
