Mode 2—Switch in the
out
position. Use this mode to connect a terminal to the console port using
the Catalyst 5000 family Supervisor Engine III console cable and appropriate adapter for the
terminal connection (cable and adapter are not provided).
See the
“Console Port Mode 2 Signaling and Pinouts” section on page B-10
.
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-8
.) 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.)
