2.5 LED Cables
There is no SGPIO supported in the most of old version SATA back-
plane. The 6Gb/s SAS controller also provides two kinds of alterna-
tive LED cable header to support the fault/activity status for those
backplanes. The global indicator connector is used by the server
global indicator LED.
The following electronics schematic is the 6Gb/s SAS RAID control-
ler logical of fault/activity header. The signal for each pin is cathode
(-) side.
The following diagrams and descriptions describe each type of con-
nector.
Note:
A cable for the global indicator comes with your computer
system. Cables for the individual drive LEDs may come with a
drive cage, or you may need to purchase them.
A: Individual Activity/Fault LED and Global Indicator Con-
nector
Most of the backplane has supported the HDD activity from the
HDD. The 6Gb/s SAS RAID controller also provides the fault activity
for fault LED. Connect the cables for the drive fault LEDs between
the backplane of the cage and the respective connector on the
6Gb/s SAS RAID controller.
The following table is the fault LED signal behavior.
