HARDWARE INSTALLATION
If the system will use only a single global indicator, attach the
LED to the two pins of the global activity/cache write-pending
connector. The global fault pin pair connector is the overall fault
signal. This signal will light up in any disk drive failure.
The following diagrams show all LEDs, connectors and pin
locations.
