J.4.15 How Do I Replace the Alarm Interface Panel?

The Alarm Interface Panel (AIP) provides surge protection for CTC-based NEs. This panel has a
nonvolatile memory chip that stores the unique node address known as the MAC address. The MAC
address identifies the nodes that support circuits. It allows CTM to determine circuit sources,
destinations, and spans.
If an AIP fails, an alarm will be generated and the LCD display on the fan-try assemblies of the NEs will
go blank. To perform an in-service replacement of the AIP, you must contact Cisco technical support.
For contact information, go to the technical support website at http://www.cisco.com/tac.
You can replace the AIP on an in-service system without affecting traffic by using the circuit repair
feature. See 7.2.10 Repairing a Circuit, page 7-66.
J.5 Client Debug Messages
On Windows, you can start the CTM client with a console window that displays exceptions and client
debug messages. You can use these messages to help troubleshoot any client problems.
Step 1 Depending on your network size, enter one of the following commands to start the client with a console
window:
/bin/ctm-small-debug.exe
/bin/ctm-medium-debug.exe
/bin/ctm-large-debug.exe
/bin/ctm-highend-debug.exe
Step 2 When the CTM client exits, the console window closes. If you want to capture and save the messages
when the client exits, you must redirect the output to a file. In this case, the console will not be displayed.
To save exceptions to a file, open one of the following files that corresponds to your network size:
•/bin/ctm-small-debug.lax
•/bin/ctm-medium-debug.lax
•/bin/ctm-large-debug.lax
•/bin/ctm-highend-debug.lax
Note It is strongly recommended that you save a copy of the original .lax file before modifying it.
Step 3 Using a text editor, open the appropriate .lax file and change the following lines by replacing “console”
with a filename:
lax.stderr.redirect=console
lax.stdout.redirect=console
When specifying filenames, make sure to use escaped backslashes (such as c:\\myfolder\\client.log). For
example, to save messages to the C:\myfolder\client.log file, change the lines to read:
lax.stderr.redirect=c:\\myfolder\\client.log
lax.stdout.redirect=c:\\myfolder\\client.log
Step 4 After modifying the .lax file, enter one of the following commands to launch the CTM client:
/bin/ctm-small-debug.exe
/bin/ctm-medium-debug.exe
