RJ45 Roll-Over Cable

Reference and Sources:

• Cisco Systems, Inc.

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. 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.
