Identifying a Rollover Cable
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-6.) 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.)
