It is recommended that you install one main and one backup set of OPC circuit packs in each span of control.

When equipped, the OPC storage is a double-slot width circuit pack and it is installed in slot 3 and 4 of the control shelf. The OPC controller is installed in slot 5 of the control shelf. The OPC interface is installed in slot 12 of the control shelf.

Ciena no longer supports any modules for the LH1600 system.
