424 Maintenance
When the ITG-Pentium 24-port trunk card starts up, it performs multiple
self-tests. The faceplate display shows the test results.
If self-tests T:00-T:09 fail, the self-test program stops and the faceplate
displays an "F:xx" message to indicate which test failed. For example, if the
timer test T:05 fails, "F:05" is displayed. If more than one test fails, the
message displayed indicates the first failure.
If self-tests T:10-T:17 fail, the display contains the failure message for three
seconds and the ITG-Pentium 24-port trunk card goes on to the next test. If
more than one test fails, the message displayed indicates the last failure.
