For information about the signals and pinouts for the Supervisor Engine 2 console port in mode 2, see the "Console Port Mode 2 Signaling and Pinouts (Sup2 Only)" section on page B-13. The accessories kit includes these items: • RJ-45-to-RJ-45 rollover cable • RJ-45-to-DB-9 female DTE adapter (labeled "Terminal") • RJ-45-to-DB-25 female DTE adapter (labeled "Terminal") • RJ-45-to-DB-25 male DCE adapter (labeled "Modem") 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-1.) If 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).
