Maintaining The Msdl - Avaya Nortel Communication Server 1000 Reference

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.

substate appears in

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.
