Replacing MSDL cards
After completing MSDL troubleshooting you may determine that one or more MSDL cards are
defective. Remove the defective cards and replace them with new ones.
Replacing an MSDL card
An MSDL card can be removed from and inserted into a system module without turning off the
power to the module. Follow these steps:
1. Log in on the maintenance terminal.
2. At the > prompt, type
LD 37
(you can also use LD 42, LD 48, or LD 96) and press
Enter.
3. Type
DIS MSDL x ALL
and press Enter to disable the MSDL and any active
operations running on one or more of its ports. The MSDL card is now disabled.
4. Disconnect the cables from the MSDL faceplate connectors.
5. Unlatch the card-locking devices, and remove the card from the module.
6. Set the switches on the replacement card to match those on the defective card.
7. Insert the replacement card into the same card slot.
8. Observe the red LED on the front panel during self-test. If it flashes three times and
stays on, it has passed the test. Go to step 8.
9. If it does not flash three times and then stay on, it has failed the test. Pull the MSDL
partially out of the module and reinsert it firmly into the module. If the problem
persists, troubleshoot or replace the MSDL.
10. Connect the cables to the MSDL faceplate connectors.
11. At the . prompt in the LD 37 program, type
ENL MSDL x ALL
and press Enter to
enable the MSDL and its operations. If the red LED on the MSDL turns off, the MSDL
is functioning correctly. Because of self-tests were not invoked, no result message
appears.
12. Tag the defective card(s) with a description of the problem and return them to your
Nortel representative.
