2x8-pin header
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.
