Module Problems
The screen below appears only if the test fails.
Lines 3 and 4 identify the cause of the failure or the number of errors found per
B-channel. On an MLX module, there are 16 B-channels, numbered 0 through
15. Line 3 displays the results for B-channels 0 through 7; Line 4 is for
B-channels 8 through 15.
Interpreting Test Results
If the test completes successfully, the module’s board controller is functioning
properly. Continue with the next module test or restore the module if you are
finished testing. If the test fails, find the error message in Table 4-5
and proceed
as indicated.
