Troubleshooting Hardware Problems
Determining Operating Status 5-35
2. To test one or more components, enter one of the commands listed in Table 5-38; all commands are
entered in exec mode. Table 5-35 lists the values for the level-num and loop-num arguments. The
arguments slot, slot1, slot2, and slotn are chassis slot numbers for the traffic cards to be tested.
Table 5-39 lists the alarm conditions, alarm status, FAIL LED status, status of other LEDs, ODD history,
log, and status for a card after an ODD session during which the card failed one or more tests; and the affect
on these indicators by the clear diag command (in exec mode), a reload of the system, the replacement,
reload, or change of state of the card, or an ODD session that the card passed successfully.
To view the results, see the “Administer Results from an ODD Session” section.
Return a Traffic Card to the In-Service State from the ODD State
After testing a traffic card, you must return it to the in-service state. To return the traffic card to the
in-service state from the ODD state, perform the tasks described in Table 5-40; you must enter the no form
of the on-demand diagnostic and shutdown commands.
