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.
After completing your configuration changes, you must remove the serial console cable from the access
Note
point.
