Troubleshooting
This chapter helps you to isolate and solve problems with your unit. In the event this chapter does not provide a solution,
or the solution does not solve your problem, check our support website at http://support.proxim.com.
Before you start troubleshooting, it is important that you have checked the details in the product documentation. For
details about RADIUS, TFTP, terminal and telnet programs, and Web browsers, refer to their appropriate
documentation.
In some cases, rebooting the unit clears the problem. If nothing else helps, consider a Soft Reset to Factory Default or a
Forced Reload. The Forced Reload option requires you to download a new image file to the unit.
See the following:
• Connectivity Issues
• Communication Issues
• Setup and Configuration Issues
• VLAN Operation Issues
• Link Problems

• Data bits 8
• Stop bits: 1
• Flow control: None
• Parity: None
4. Ensure that the unit and the computer use the same serial port configuration parameters.
