410 NT6D80 MSDL card
The system disables the MSDL if the card:
•
exhibits an overload condition
•
does not respond to system messages
•
is removed
•
resets itself
•
encounters a fatal error
•
is frequently system disabled and recovered
When an MSDL is system disabled, a substate indicates why the MSDL is
disabled. The substates are:
•
Not Responding The system cannot communicate with the MSDL.
• Self-Testing The MSDL card is performing self-tests.
•
Self-tests Passed The MSDL card successfully completed self-tests
and the system is determining if download is required or the software
downloading is complete.
•
Self-tests Failed The MSDL card self-tests failed.
•
Shared RAM Tests Failed The system failed to read/write to the MSDL
shared RAM.
•
Overload The system received an excessive number of messages
within a specified time period.
• Reset Threshold The system detected more than four resets within
10 minutes.
•
Fatal Error The MSDL card encountered a fatal condition from which it
cannot recover.
•
Recovery Threshold The MSDL card was successfully enabled by
the MSDL autorecovery function five times within 30 minutes. Each
time it was system disabled because of a problem encountered during
operation.
•
Bootloading The MSDL base software is in the process of being
downloaded to the MSDL.
Detailed information on system disabled substates and the action required
for each substate appears in "Symptoms and actions" (page 415).
Maintaining the MSDL
The system controls automatic MSDL maintenance functions. A
craftsperson or system administrator performs manual maintenance by
changing the card status, downloading new versions of peripheral software,
or invoking self-tests.
