Checking Console Messages
Useful diagnostic messages may be displayed on the console screen when the
access point is reset. As described in chapter 2 under step 7, “Connect a
console to the access point”, connect a PC running a VT-100 terminal emulator
program or a standard VT-100 terminal to the access point’s Console Port and
configure it to run at 9600 baud, and with the other terminal communication
settings shown on page 2-11. Then, when you reset the access point, note the
messages that are displayed. Additionally, you can check the access point’s
event log, which can be accessed from the console using the
