LSISAS9212-4i4e HBA Characteristics
3.1.5.1
Memory
The LSISAS9212-4i4e HBA provides one 4-M × 8-bit Flash ROM for storing the firmware and BIOS. The LSISAS9212-4i4e
HBA can provide up to 32 K × 8-bit NVSRAM for storing nonvolatile RAID information when a system failure occurs.
3.1.5.2
LEDs
The LSISAS9212-4i4e HBA has a 4-pin header for external connection of activity LEDs. The 4-pin header connects to
two LEDs (see
3.1.5.3
Connectors
This section describes the different connectors on the LSISAS9212-4i4e HBA. See
PCIe Connector (J1). The LSISAS9212-4i4e HBA supports a x8 interface. The PCIe host interface connection is
through the edge connector, J1, which provides connections on both the top (J1B) and bottom (J1A) of the board. The
signal definitions and pin numbers conform to the PCIe specifications.
SAS/SATA Connector (J5, J6, J7, J8, and J12). The LSISAS9212-4i4e HBA supports SAS/SATA connections through
connector J12, which is an SFF-8088 mini-SAS, external, right-angle connector, and connectors J5, J6, J7, and J8, which
are 7-pin SATA connectors.
Activity LED Header (J11). The LSISAS9212-4i4e HBA has a 4-pin, right-angle, 0.1-in. pitch header for driving external
activity LEDs.

Port 1 consists of the 7-pin SATA connectors on this HBA.
UART Connector (J4). The UART connector debug port requires a special cable and LSI support to gather detailed
IOC status.
