Cisco MGX 8220 ASC Shelf Controller

The Cisco MGX 8220 shelf controller (ASC) is a two-card set consisting of an ASC front card and an ASC-BC back card. The shelf can contain a single ASC card set or a dual (redundant) card set.

The ASC provides overall control of the shelf through the cell bus. The ASC back card provides console ports for a user interface to configure and manage the shelf.

The ASC cards are installed in slot 3 and or slot 4. An illustration of the ASC card set is provided in Figure 2-11.
