This section helps you locate problems related to the AP-600 device setup. For details about RADIUS, TFTP,
serial communication programs (such as HyperTerminal), Telnet applications, or web browsers, please refer to
the documentation that came with the application for assistance.
Troubleshooting Concepts
The following list identifies important troubleshooting concepts and topics. The most common initialization and
installation problems relate to IP addressing. For example, you must have valid IP addresses for both the AP-600 and
the management computer to access the unit's HTTP interface.
•
IP Address management is fundamental.
•
Factory default units are set for "Dynamic" (DHCP) IP Address assignment. The default IP address for the
AP-600 is 169.254.128.132 if your network does not have a DHCP server. If you connect the AP-600 unit to a
network with an active DHCP server, then use ScanTool to locate the IP address of your unit. If a DHCP server is
not active on your subnet, then use ScanTool to assign a static IP address to the unit.
•
The Trivial File Transfer Protocol (TFTP) provides a means to download and upload files. These files include
the AP-600 Image (executable program) and configuration files.
•
If the AP-600 password is lost or forgotten, you will need to reset to default values. The
Default Procedure
resets configuration, but does not change the current AP Image.
•
If all else fails... Use the
image. Once the new image is loaded, use the
values and reconfigure the unit.
•
The AP-600 Supports a Command Line Interface (CLI). If you are having trouble locating your AP-600 on the
network, connect to the unit directly using the serial interface and refer to
command syntax and parameter names.
