Symptoms and Solutions
Connectivity Issues
Connectivity issues include any problem that prevents you from powering up or connecting to the AP-600.
AP-600 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-600 correctly.
3. If you are using Active Ethernet, make sure you are using a Category 5, foiled, twisted pair cable to power the
AP-600.
Serial Link Does Not Work
1. Make sure you are using a standard, straight-through, 9-pin serial cable.
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)
Ethernet Link Does Not Work
1. Double-check the physical network connections. Use a known-good unit to make sure the network connection is
present. Once you have the AP-600 IP address, you can use the "Ping" command over Ethernet to test the IP
Address. If the AP-600 responds to the Ping, then the Ethernet Interface is working properly.
2. By default, the Access Point will attempt to automatically detect the Ethernet settings. However, if you are having
problems with the Ethernet link, manually configure the Access Point's Ethernet settings. For example, if your
switch operates at 100 Mbits/sec/Full Duplex, manually configure the Access Point to use these settings (see
Ethernet). If you cannot access the unit over Ethernet, then use the CLI interface over the serial port to configure
the Ethernet port (see
3. Perform network infrastructure troubleshooting (check switches, routers, etc.).
Basic Software Setup and Configuration Problems
Lost AP-600, Telnet, or SNMP Password
1. Perform the
Reset to Factory Default Procedure
parameters, but does not affect the AP-600 Image.
The default AP-600 HTTP password is "public", and the default Telnet password is also "public".
Client Computer Cannot Connect
1. Client computers should have the same Network Name and security settings as the AP-600.
2. Network Names should be allocated and maintained by the Network Administrator.
3. Refer to the documentation that came with your client card for additional troubleshooting suggestions.
AP-600 Has Incorrect IP Address
1. Default IP Address Assignment mode is dynamic (DHCP). If you do not have a DHCP server on your network, the
default IP Address is 169.254.128.132. If you have more than one unintialized AP-600 connected to the network,
they will all have the same default IP address and you will not be able to communicate with them (due to an IP
address conflict). In this case, assign each AP a static IP address via the serial cable or turn off all units but one
and change the IP address using ScanTool one at a time.
2. The AP-600 only contacts a DHCP server during boot-up. If your network's DHCP server is not available while the
AP-600 is booting, the device will retain the last IP Address it had. Reboot the AP-600 once your DHCP server is
on-line again or use the ScanTool to find the Access Point's current IP address.
