October 2014 LSI SAS 9212-4i4e HBA Characteristics
Activity LED Header (J11). The LSI SAS 9212-4i4e HBA has a 4-pin, right-angle, 0.1-in. pitch header for driving
external activity LEDs.The 4-pin header connects to two LEDs, which indicate SAS activity on Port 0 and Port 1.
UART Connector (J4) The UART connector debug port requires a special cable and LSI support to gather detailed
input/output controller (IOC) status.
5.3 Physical Characteristics
The LSI SAS 9212-4i4e HBA is a 6.6-in. x 2.7-in., low-profile board. The component height on the top and bottom of the
LSI SAS 9212-4i4e HBA is in accordance with the PCIe specification. The following figure shows the board connectors.
