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 to 3
Ports 4 to 7
2x8-pin connector
Connects to an LED array 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.
J1B3 Advanced Software Options Hardware Key header 2-pin header
Enables support for the Advanced Software Options
features, which include CacheCade, FastPath, Recovery, and
SafeStore disk encryption.
