Identifying a Roll-Over Cable
You can identify a roll-over cable by comparing the two modular 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 A-1). If your cable came from Cisco Systems, pin 1 will be white on one
connector, and pin 8 will be white on the other (a roll-over cable reverses pins
1 and 8, 2 and 7, 3 and 6, and 4 and 5).
