Note: The paddle board contains the Ethernet address, verify that the new
board’s DIP switches are set to the same address as the one being replaced. See
Figure 6.6-2 and Table 6.6-1.
Table 6.6-1 — Switching Module DIP Switch Settings

Response: The OFF lamp is extinguished.
11. Test the new paddle board. At the MCC terminal, type and enter:
DGN:MCTSI=a-b,PH=12,TLP;
Where: a = The switching module number.
b = The MCTSI number (0 or 1).
12. Is the diagnostic response ATP?
If YES, STOP. YOU HAVE COMPLETED THIS PROCEDURE
If NO, continue with Step 13.
13. Warning: The following step will cause an expected loss of
communication between the switching module and the workstation.
Replace the T-connector of the new paddle board.
14. Test the new T-connector. Type and enter the input command used in Step 11.
15. Is the diagnostic response ATP?
If YES, STOP. YOU HAVE COMPLETED THIS PROCEDURE
If NO, continue with Step 16.
16. Warning: The following step will cause an expected loss of
communication between the switching module and the workstation.
Repeat steps 3 and 4, then replace the other T-connector.
17. Test the second new T-connector. Type and enter the input command used in Step
11.
18. Is the diagnostic response ATP?
