Routine Maintenance

14. Disconnect the fiber cables from the EL/ML control cabinet. Label the

Tx and Rx cables, identify the Bay that the cables connect to, and label

the front of the SX-200 ICP MX controller to ensure that connections

are made to the proper bays.

15. Remove the main control card from the EL/ML control cabinet.

16. Install the required peripheral CIM or FIM cards into the EL/ML

cabinet(s).

17. Remove all CIM and FIM triple modules from the SX-200 EL/ML

control cabinet.

18. Connect all bays to CIMs or FIMs.

19. Power up the EL/ML cabinet(s).

20. Verify that the migration succeeded by placing calls to and from sets

connected to the Peripheral Cabinet(s). Test the voice mail system by

leaving, retrieving, and deleting messages. Verify that features

function properly, especially call forwarding.

21. Back up the SX-200 ICP database using FTP. (See page 199.)

22. To prevent unnecessary alarms:

• In Maintenance, revise the Alarm Thresholds.

• In Form 53, check the bay number assignments. If a bay is

assigned a bay number, it must be connected to a physical device;

otherwise, it will generate an alarm. To prevent this problem, move

disconnected bays from physical connections (CIMs and MMCs) to

phantom bays.

Note: A system with a BCC III may take as long as 20 minutes to

come up following the upgrade. Subsequent reboots will not incur

this delay.
