Troubleshooting for Power-Over-Ethernet (PoE)
The PoE Does Not Work
1. Verify that you are using a standard UTP Category 5 cable.
2. Try a different port on the same PoE hub (remember to move the input port accordingly) – if it works, there is probably
a faulty port or bad RJ-45 port connection.
3. If possible, try to connect the MeshMAX unit to a different PoE hub.
4. Try using a different Ethernet cable – if it works, there is probably a faulty connection over the long cable, or a bad
RJ-45 connection.
5. Check power plug and hub.
6. If the Ethernet link goes down, check the cable, cable type, switch, and hub.
Troubleshooting Concepts for Subscriber Module
This section helps you to isolate and solve problems with your Subscriber Module. 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, check 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 Subscriber Module 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
Subscriber Module.
Connectivity Issues
Subscriber Module Does Not Boot
The Subscriber Module shows no activity (the power LED is off).
1. Ensure that the power supply is properly working and correctly connected.
2. Ensure that all cables are correctly connected.
3. Check the power source.
4. If you are using an Active Ethernet splitter, ensure that the voltage is correct.
Cannot use the Web Interface
1. Open a command prompt window and enter ping <ip address unit> (for example ping 10.0.0.1). If the unit
does not respond, make sure that you have the correct IP address. If the unit responds, the Ethernet connection is
working properly, continue with this procedure.
2. Ensure that you are using Microsoft Internet Explorer 5.0 or later (version 6.0 or later recommended) or Netscape 6.0
or later.
3. Ensure that you are not using a proxy server for the connection with your Web browser.
4. Ensure that you have not exceeded the maximum number of Web Interface or CLI sessions.
5. Double-check the physical network connections. Use a well-known unit to ensure the network connection is properly
functioning.
6. Perform network infrastructure troubleshooting (check switches, routers, and so on).
