Overview
Overview
The access point requires a special serial cable that connects the access point serial console port (RJ-45
connector) to your PC's COM port (DB-9 connector). This cable can be purchased from Cisco (part
number AIR-CONCAB1200) or can be built using the pinouts in this appendix.
Console Port Signals and Pinouts
Use the console RJ-45 to DB-9 serial cable to connect the access point's console port to the COM port
of your PC running a terminal emulation program.
Both the Ethernet and console ports use RJ-45 connectors. Be careful to avoid accidently connecting the
Note
serial cable to the Ethernet port connector.
When your configuration changes are completed, you must remove the serial cable from the access point.
