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.
