5.
Connect SAS cables between the HBA and the SAS backplane or any other SATA or SAS device.
The 12Gb/s
SAS HBA has SFF-8643, internal x4, mini-SAS HD connectors. Use cables with an internal mini-SAS HD connector
on one end (to connect to the HBA) and the appropriate connector on the other end to attach to the backplane or
SAS/SATA devices.
6.
Make sure the system provides the required airflow for the controller.
Airflow must be at least 200 linear feet
per minute (LFM) at 55 °C inlet temperature to avoid operating the SAS 3216 processor above the maximum
junction temperature.
7.
Replace the cover and reconnect any cords and cables, and power up the system.
Replace the chassis cover,
reconnect any power cords, and reconnect any network cables. Turn on the power.

Configuring the 9305-16i HBA with Port Widths Greater than x1
The SAS 3324 device has 24 SAS PHYs. The PHYs are managed in groups of eight by dedicated hardware in ascending
PHY order. PHYs 0 to 7 are managed by one dedicated instance of the SAS PHY management hardware, PHYs 8 to 15
are managed by a second instance of the SAS PHY management hardware, and PHYs 16 to 23 are managed by a third
instance of the SAS PHY management hardware. These SAS PHY management hardware instances, or SAS cores,
cannot communicate with each other.
When configuring a wide port using the 9305-16i controller, the connections must be attached exclusively to PHYs that
are all managed by the same SAS core. If they are not managed by the same SAS core, then unexpected controller and
host behavior will occur. By default, the connectors are mapped as shown in

.
Board ports 0 through 7 are connected to PHYs on the SAS 3324 device that are managed by SAS Core 1. Board ports
8 through 15 are connected to PHYs that are managed by SAS Core 0.
