assistance with re-loading the kernel and application software.
e. Note down the reciter’s IP address that is displayed at the login
prompt and close the session.
4. Connect the PC to the network board over its digital Ethernet line.
a. Using the IP address you noted down, ping the reciter from the
Windows command prompt. If there is a response, the network
board’s Ethernet interface circuitry is functioning in both
directions. If there is no response, replace the board.
b. Attempt to connect the CSS to the reciter. If this is successful, the
network board application is running. Check the Alarm Status
screen for reciter alarms. Carry out the control panel LED diag-
nostic test.
5. If there is no obvious hardware fault, replace the current firmware
and/or kernel to see if this fixes the problem.
a. If possible, use the CSS to upload the firmware.
b. Otherwise, follow TN-997 to replace the kernel and/or the
firmware using telnet and a TFTP server.
6. Exclude the base station configuration as the source of problems by
programming in a new configuration.
a. In the CSS, connect to the reciter.
b. Read the configuration and save it to file.
c. Select File > New.
d. Modify the new configuration as necessary.
e. Program the new configuration into the reciter, leaving its current
IP address and netmask.
7. Attempt to access the bootloader prompt. If this is unsuccessful, the
bootloader is faulty. The reciter will need to be returned to Tait
Electronics Limited for the bootloader to be repaired.
8. If the network board fails some or all of the above tests, replace it as
described below.
1.3 Before You Start
Make sure you have a backup of the current base station configuration.
