Appendix B Using BOOT Loader

Viewing a list of fatal system exceptions

A fatal system exception occurs when the Central Processing Unit (CPU) detects an error such as a division by zero, or accesses to non-existent memory. A fatal exception causes the M770 ATM Switch to reboot. A breakpoint is a special type of exception which is invoked by the M770 ATM Switch software when it detects an internal inconsistency.

To dump a list of fatal system exceptions, use the system breaklog command.

Command:

M15-155s8:/>system breaklog

Output:

Filename:

lmaux.c

 

Line No:

553

 

pml_time:

Stablised Count:

Note: The breaklog provides vital information for diagnosing why the M770 ATM Switch has crashed. This information needs to be reported to Avaya Technical Support.

Clearing the list of fatal system exceptions

To clear the list of fatal system exceptions, use the system breaklog clear command.

Command: M15-155s8:/>system breaklog clear

Running all the hardware tests

You can run all the non-critical hardware tests on a M770 ATM Switch. If all the tests pass the M770 ATM Switch will respond with DONE!

If a test fails, then the BOOT Loader will display the test that has the failed and the M770 ATM Switch LEDs will display the sequence that represents the error. For more information about the LED status sequence, see the Module Installation Guides.

To run all hardware tests, use the system test command.

Command:

M15-155s8:/>system test
