Cable and Adapter Pinouts

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

Connecting to a PC

Use the supplied RJ-45-to-DB-9 adapter cable to connect the console port to a PC running

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. Table B-3 lists the pinouts for the console port, the adapter cable, and the

RJ-45-to-DB-25 adapter.

Note The RJ-45-to-DB-25 female DTE adapter is not supplied with the switch. You can order a kit (part

number ACS-DSBUASYN=) with that adapter from Cisco.
