3.1
Characteristics of the LSI 6Gb/s HBAs
The following sections present the memory, LED, connector, and physical characteristic information for each LSI
6Gb/s HBA.
3.1.1
LSISAS9200-8e HBA Characteristics
3.1.1.1
Memory
The LSISAS9200-8e HBA provides one 4-M × 8-bit Flash ROM for storing the firmware and BIOS.
3.1.1.2
LEDs
The LSISAS9200-8e HBA has a 4-pin header for connection of activity LEDs. The 4-pin header connects to two LEDs
(see
Table
4), which indicate SAS activity on Port 0 and Port 1.
3.1.1.3
Connectors
This section describes the different connectors on the LSISAS9200-8e HBA. See
PCIe Connector (J7). The LSISAS9200-8e HBA supports a x8 interface. The PCIe host interface connection is through
the edge connector, J7, which provides connections on both the top (J7B) and bottom (J7A) of the board. The signal
definitions and pin numbers conform to the PCIe specification.
SAS/SATA Connectors (J4 and J5). The LSISAS9200-8e HBA supports SAS/SATA connections through connectors J4
and J5, which are SFF-8088 mini-SAS, external, right-angle connectors.
Activity LED Header (J3). The LSISAS9200-8e HBA has a 4-pin, right-angle, 0.1-in. pitch header for driving external
activity LEDs.

UART Connector (TP2). The UART connector debug port requires a special cable and LSI support to gather detailed
Input/Output Controller (IOC) status.
