The following diagrams are used to help identify the mini-SAS connectors found on the SAS
expander cards. Care should be taken when connecting connectors from the SAS expander to
the connectors on the backplane because each connector is pre-programmed at the factory to
provide specific drive identification mapping. Improper connections may provide undesirable
drive mappings.
