Serial Link Does Not Work
If the 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);
l
Baud rate: 9600; Data bits: 8; Stop bits: 1; Flow Control: None; Parity: None;
l
Line Feeds with Carriage Returns (In HyperTerminal select: File > Properties >
l
Settings > ASCII Setup > Send Line Ends with Line Feeds)
Ethernet Link Does Not Work
If the 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
Configuration
interface over the serial port to configure the Ethernet port (see
Line
Interface).
3. Perform network infrastructure troubleshooting (check switches, routers, etc.).
