Attention: To avoid damage to the hardware, make sure that you align the
black dot on the cable connector with the black dot on the connector on the
interposer card. Do not force the remote battery cable into the connector.
22. Connect the SAS signal cables to the connectors on the SAS controller:
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 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.
