 NT6D80 MSDL card

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. 

An MSDL card can be removed from and inserted into a system module 
without turning off the power to the module. Follow these steps:

Log in on the maintenance terminal.

At the > prompt, type LD 37 (you can also use LD 42, LD 48, or LD 96) 
and press Enter.

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.

Disconnect the cables from the MSDL faceplate connectors.

Unlatch the card-locking devices, and remove the card from the module.

Set the switches on the replacement card to match those on the defective 
card.

Insert the replacement card into the same card slot.

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. 

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. Since 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 Networks representative.
