c. From the front side of the SAS controller, install the two screws that hold
the metal bracket onto the SAS controller.

interposer card. Do not force the remote battery cable into the connector.
a. Connect the shorter SAS signal cable that comes with the option kit to the
SAS controller connector that is labeled "Ports 7-4". If you are connecting
cables to a ServeRAID-MR10i SAS/SATA Controller, this connector is
closest to the edge of the controller and has two straight connectors.
Note: If you are connecting the shorter SAS signal cable to a
ServeRAID-BR10i v2 SAS/SATA Controller, the connectors are reversed.
You must connect the shorter SAS signal cable to the connector that is
labeled "Port 4–7", which is the connector that is not the closest to the
edge of the controller.
