Recovering a Lost IP address
Use a DB-9 serial cable to access the base station serial console. The configuration of
the serial port should be 57,600 bps, no parity, 8 data bits, 1 stop bit. Once connected,
type in the command

Troubleshooting the Web Interface
These troubleshooting steps assume that the status LEDs on the front panel of the
terminal indicates normal function.
terminal indicates normal function.
1. Open a Web browser and attempt to login to the base station terminal. If the terminal
does not respond by displaying the login dialog box, check that the correct IP
address is being used. The factory default address is listed in the Troubleshooting
section. The IP address may have been changed during installation. For correct
operation the host computer and the terminal must appear to be on the same subnet.
Ensure that the IP address for the PC is set to the same subnet as the terminal. For
example, the IP address should only differ in the last octet (i.e., 192.168.101.X).

2. The next test is to verify the IP address is reachable from the computer. Use the ping
command to test the connection between the terminal and host computer. The
system always responds to ping frames less that 577 bytes in length.

If the ping test is successful the host computer was able to send and receive
packets. The problem may be with the Internet browser or related settings on the
host computer. Re-boot the host computer to try to resolve the problem. If the ping is
not successful, the IP address may be incorrect, or a duplicate address may exist.

not successful, the IP address may be incorrect, or a duplicate address may exist.
3. If the current address of the terminal cannot be determined, it is recommended to
perform a long-reset. Performing a long-reset restores the terminal IP address and IP

Re-Ranging Log Message
The log message 're-ranging' is recorded by the base station when a registered
subscriber initiates a network entry sequence.
subscriber initiates a network entry sequence.
There are two common reasons for this event:
1. When network entry is complete, the subscriber retains its 'registered' state by
sending data traffic to the base station. When there is no data traffic, the SU-O sends
only periodic ranging requests each 25 seconds. Under no-traffic conditions, it may
