Step 5. Install the LED Cable (Optional)
The Global Indicator Connector is used by the server global
indicator LED.
The following electronics schematic is the ARC-1330-4i4x/ARC-
1330-8i host adapters 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.
Global LED Indicator Connector
If the system will use only a single global indicator, attach the LED
to the two pins of the global fault/activity connector. The global
fault pin pair connector is the overall fault signal. This signal will
light up in any internal disk drive failure. The global activity pin
pair connector is the overall activity. This global activity signal will
light up in any internal disk activity.
