Troubleshooting
Use the following procedures to resolve any problems you may encounter with the SX-2000
ApSU.
Check The LED Indicators
Check the LEDs on the front panel of the SX-2000 ApSU.
LEDStatusIndicates
MSLit steadyWhether or not the message link to the
SX-2000 PBX is functioning. If it is lit, the
message link is up which is the operational
state.
STBlinking on and off every ½ secondThe SX-2000 ApSU has not locked up and
that different tasks are still getting CPU time.
If the ST LED is on all the time or off all the
time, the SX-2000 ApSU has probably locked
up and will require a reboot/reset.
FTP Client Cannot Connect To SX-2000 ApSU
1. Verify that the SX-2000 ApSU is operational by checking its LED’s.
2. Verify that the FTP client is connecting to the correct IP address for the SX-2000 ApSU using
the ping command to test the IP address of the SX-2000 ApSU. If no reply is received, there
may be a network problem between the PC and the SX-2000 ApSU or there may be a
problem with the SX-2000 ApSU itself.
3. If the IP address of the SX-2000 ApSU is not known, the following procedure must be used.
You will need to take the SX-2000 ApSU out of service.
- Connect to the serial port of the SX-2000 ApSU and initiate the Hyperterminal application
on the PC.
- Reboot/reset the SX-2000 ApSU. 
- Watch the output from the SX-2000 ApSU carefully as it is displayed. The messages
displayed will include the IP address that the SX-2000 ApSU is configured with on the
line that begins with inet on ethernet. For example:

4. If the steps listed above do not resolve the problem, perform a reboot/reset.
- Connect to the SX-2000 ApSU via the serial connector and start the Hyperterminal
application on the PC.
- Reboot/reset the SX-2000 ApSU.
- Press any key on the keyboard when prompted by Hyperterminal to stop the auto-
boot process. A prompt should appear reading: [MC269AA Boot]-:
- Enter c and change the value of the boot device parameter from flash to qu. The
remaining values can remain unchanged but the boot device must be set to qu for
the Q command to function. If the parameter is not defined properly, entering the Q
command will lock up the SX-2000 ApSU and it will need to be rebooted/reset.
- Enter Q to initiate a quick reboot that will create the flash file system and bring up just
the FTP server. It will not try to start the HCI or MiTAI servers.
Note:When the SX-2000 ApSU is running in this mode, the ST LED will not blink.
MiTAI Client Cannot Connect To MiTAI Server On SX-2000 ApSU
1. Verify that the SX-2000 ApSU is operational by checking its LED’s.
2. Verify that the MiTAI Client is configured with the SX-2000 ApSU’s IP address and the Port
Number is defined as 8000.
3. Verify that the SX-2000 ApSU’s IP address returns data when tested using the ping
command.
4. Connect to the SX-2000 ApSU using FTP and enter the dir command to verify that the
correct files are present.
5. Use FTP to copy the MTC.LOG file from the SX-2000 ApSU onto the PC using the get
command. This is a circular log and so while it may be read using any text editor, the latest
log messages may not be at the bottom of the file. Interpreting the unprocessed log file is

best left to product support and design personnel. If the logs viewer application is available, it
can be used to copy the logs onto the PC and read the log messages.
Reconfiguring The SX-2000 ApSU Flash Memory
1. Connect a serial cable (34800, straight-through cable) to the maintenance port of the
SX-2000 ApSU.
2. Ensure that you are using a PC connected to the same Network as the SX-2000 ApSU (on
the same subnet or accessible via a router).
3. Copy the following files obtained from Mitel Networks Product Support to a folder on the PCs
hard drive:
- Datetag.txt,
- ApSUmain.cmd,
- ApSUapps.cmd,
- Hcivxwk.out,
- mitaivxw.out,
- vxworks,
- mtc.log,
- apcucore.o,
- pri_fpga.bin
4. Disconnect the fiber-optic cable from the SX-2000 ApSU to prevent it from resetting.
5. Open a terminal emulator program using the serial connection (38400, 8-N-1) to the SX-2000
ApSU.
6. Reset the ApSU.
7. Stop the automatic countdown by pressing any key.
8. At the [MC269AA Boot]-: prompt, enter c to change the boot parameters.
9. Change the boot device parameter from flash to qu.
10. Enter R to reformat the file system on the SX-2000 ApSU.
CAUTION: All files in the SX-2000 ApSU will be deleted! The SX-2000 ApSU will initialize
with just an FTP server operational. This is similar to the Q command but with the addition
of reformatting the file system.
The file system has now been reformatted. Use FTP to transfer a copy of all the SX-2000 ApSU
software files onto the SX-2000 ApSU file system.
The boot parameters will need to be changed back to their original settings. Use the reboot
procedure described above to change the boot parameters back although only the boot device
and other parameters need to be changed back since the other revised parameters will be
ignored when boot device is set to flash. Once the parameters have been changed using the c
command, reboot the SX-2000 ApSU to bring it back into service.
