Troubleshooting
NOTE
This section helps you locate problems related to the AP-2500 device setup. For details about RADIUS, TFTP,
Serial communications program (such as HyperTerminal), Telnet applications or web browsers, please refer to
their respective documentation.
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-2500
device and the TFTP server before you can transfer files over Ethernet.
•
IP Address management is fundamental.
• Factory default units are set for “Dynamic” (DHCP) IP Address assignment. The default IP Address for the
AP-2500 is 10.0.0.10. If you connect the AP-2500 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 the ScanTool can be used
to configure your AP-2500.
• The Trivial File Transfer Protocol (TFTP) provides a means to download and upload files. These files include
the AP-2500 Image (executable program) and configuration files.
• If the AP-2500 password is lost or forgotten, you will need to reset to default values. The Reset to Factory
Default Procedure resets configuration, but does not change the current AP Image.
• If all else fails… The Forced Reload Procedure erases the current AP-2500 Image. Once the new image is
loaded, use the Reset to Factory Default Procedure to set the unit to factory default values and reconfigure the
unit.
• AP-2500 Supports a Command Line Interface (CLI). If you are having trouble locating your AP-2500 on the
network, connect to the unit directly using the serial interface and refer to
Using the Command Line Interface for
CLI command syntax and parameter names.
Symptoms and Solutions
Connectivity Issues
Connectivity issues include any issues that prevent you from powering up or connecting to the AP-2500 device.
AP-2500 Unit Will Not Boot - No LED Activity
1. Make sure your power source is operating.
2. Make sure all cables are connected to the AP-2500 unit correctly.
3. With Active Ethernet, make sure you are using a Category 5, foiled, twisted pair cable to power the AP-2500 unit.
Serial Link Does Not Work
1. Make sure you are using the proper serial port cable (a straight-through cable with a 9-pin female connector on
each end).
2. Double-check the physical network connections.
3. Make sure your PC terminal program (such as HyperTerminal) is active and configured to the following values:
– Com Port: (COM1, COM2, etc. depending on your computer);
– Baud rate: 9600
– Data bits: 8
– Stop bits: 1
– Flow Control: None
– Parity: None
– Line Feeds with Carriage Returns
(In HyperTerminal select:
File -> Properties -> Settings -> ASCII Setup -> Send Line Ends with Line Feeds.)
