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
you purchased your cable from Cisco Systems, pin 1 is white on one connector, and pin 8 is white on the
other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
