Troubleshooting the AP-2000

Symptoms and Solutions

Connectivity Issues

Connectivity issues include any problem that prevents you from powering up or connecting to the AP.

AP 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 correctly.

3.If you are using Active Ethernet, make sure you are using a Category 5, foiled, twisted pair cable to power the AP.

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 IP address, you can use the “Ping” command over Ethernet to test the IP Address. If the AP 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 Using the Command Line Interface (CLI) and Set Ethernet Speed and Transmission Mode).

3.Perform network infrastructure troubleshooting (check switches, routers, etc.).

Basic Software Setup and Configuration Problems

Lost AP, Telnet, or SNMP Password

1.Perform the Reset to Factory Default Procedure in this guide. This procedure resets system and network parameters, but does not affect the AP Image.

The default AP 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.

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 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 10.0.0.1. If you have more than one unintialized AP 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.
