Procedure 10 "Replace the MSDL card" (page 98)
Action
Disable the MSDL card in LD 96.
Disconnect MSDL to PRI cables.
Remove the faulty MSDL card.
Unpack and inspect the new MSDL card.
Set the MSDL switch settings to correspond to
switch settings" (page 97)
97).
Insert the new MSDL card into the selected card slot of the module
following the card guides.
Observe the red LED on the MSDL faceplate. If it turns on, flashes
three times, and stays on continuously, the MSDL is operating
correctly but is not yet enabled.
If the LED turns on and stays on continuously without flashing
three times, the card can be defective. Go to step 11.
