Cable and Adapter Pinouts

This section describes the cable and adapter pinouts and also describes how to identify a rollover cable.

terminal-emulation software.

Table B-2

lists the pinouts for the console port and the RJ-45-to-DB-9

adapter cable.

Connecting to a Terminal

Use the supplied RJ-45-to-DB-9 adapter cable and an RJ-45-to-DB-25 female DTE adapter to connect
the console port to a terminal.
