Figure B-9 Four Twisted-Pair Crossover Cable Schematics for 1000BASE-T Ports
To identify a crossover cable, hold the cable ends side-by-side, with the tab at the back. The wire
connected to pin 1 on the left end should be the same color as the wire connected to pin 3 on the right
end. The wire connected to pin 2 on the left end should be the same color as the wire connected to pin 6
on the right end.
Figure B-10 Identifying a Crossover Cable
Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector, which is described in Table B-3 and Table B-4. If you
did not order a console cable, you need to provide an RJ-45-to-DB-9 adapter cable to connect the switch
console port to a PC console port. You need to provide an RJ-45-to-DB-25 female DTE adapter if you
want to connect the switch console port to a terminal. You can order an adapter (part number
ACS-DSBUASYN=). For console port and adapter pinout information, see Table B-3 and Table B-4.
