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.

Identifying a Crossover Cable
Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector, which is described in b and
Table C-6
. 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 C-5
and
