The IAO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource type, resources, and/or resource prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.)
