Appendix B Transceiver, Chassis Connectors, and Cable and Adapter Specifications Cables and Adapters Figure B-5 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-5.) 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.) Identifying a Rollover Cable Pin 1 Pin 1 and pin 8 should be the same color Pin 8 H3824 Rollover Cable RJ-45 to DB-9 Adapter (For Connecting to a PC) Use an RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-9 female DTE adapter (labeled Terminal) to connect the console port to a PC running terminal emulation software.
