Circuit Card
Description and Installation
System disabled
When the system disables the MSDL card (step 4 in Figure 87 on
it continues to communicate and attempt maintenance procedures on the card.
To stop all system communication with the card, enter
DIS MSDL x
to disable
it (step 5 in Figure 87 on
). Otherwise, the system periodically tries
to enable the card, attempting recovery during the midnight routines (step 3
in Figure 87 on
).
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.
