Replacing a Main Controller Card
When replacing a main controller card (MCC), you must ensure that the
replacement MCC and the installed MCC match – both in card type
and stratum clock type. This procedure applies to the MCC II,
MCC IIIEL, MCC Yields, MCC IIIML, and the MCC in the SX-200
LIGHT/DIGITAL PBX.
1. Quit the customer data entry mode.
2. If you do not have an up-to-date database backup, create one now.
3. Power-down the Control cabinet.
4. Remove the old MCC.
5. Remove the system ID module or decryption module from the old
MCC and install it onto the new MCC.
6. Transfer any modules from the old MCC to the new MCC.
7. Install the new MCC.
8. Power-up the cabinet.
9. Verify the system date and time. Correct as required.
10. Restore the database.
