Diagnosing Access Point Indicators
Installation
Verify that all system components have been properly installed. If one or more components appear
to be malfunctioning (such as the power cord or network cabling), test them in an alternate
environment where you are sure that all the other components are functioning properly.
Console Access
If you cannot access the command line interface via a serial port connection, check the following
items before you contact Technical Support:
• Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit,
no parity and 9600 bps.
• Check that the serial cable conforms to the pin-out connections provided in Appendix B.
