Type Description
J1A2 Universal Asynchronous
Receiver/Transmitter (UART) for the
Expander 4-pin connector
Reserved for LSI use.
J1B1 LED Locate and Fault Indication
header
Ports 0-3
Ports 4-7
2x8-pin connector
Connects to an LED that indicates whether a drive is in a fault condition. There is one LED
per port. When lit, each LED indicates the corresponding drive has failed or is in the
unconfigured-bad state.
The LEDs function in a direct-attach configuration (there are no SAS expanders). Direct
attach is defined as a maximum of one drive connected directly to each port.
NOTE: This header is used for RAID controllers with internal SAS ports only.
J1B2 x4 SAS Ports 24-27 external
connector SFF-8088 x4 external mini SAS connector
Connects the controller by cable to a SAS/SATA backplane or an expander.
