Replace the MSDL

Replacement procedures for the MSDL card are the same for all Large Systems. Use Procedure 10 "Replace the MSDL card" (page 98) below.

Procedure 10

Replace the MSDL card

Step Action

1Disable the MSDL card in LD 96.

2Disconnect MSDL to PRI cables.

3Remove the faulty MSDL card.

4Unpack and inspect the new MSDL card.

5Set the MSDL switch settings to correspond to Table 28 "MSDL switch settings" (page 97) and Figure 40 "MSDL card layout" (page 97).

6Insert the new MSDL card into the selected card slot of the module following the card guides.

7Observe 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.
