Previously operating MSDL cards
Problems that occur during normal operation usually result from faulty cards.
Follow these steps to evaluate the situation:
1 Use the
STAT MSDL x
command to check MSDL card status. See
“Displaying MSDL status” on page 418 .
2 If the card has been manually disabled, try to enable it using
ENL MSDL x
. See “Enabling the MSDL” on page 417 . If this fails,
perform self-testing as described in step 4.
3 If the card has been disabled by the system, disable it manually with
DIS MSDL x
. See “Disabling the MSDL” on page 418 .
4 Invoke self-testing with the
SLFT MSDL x
command. See “Self-testing
the MSDL” on page 418 . If self-tests fail, replace the card. If self-tests
pass, try to enable the card again, as in step 2. If the card does not enable,
note the message output to the TTY and follow the recommended action.
