Connecting the SCSI Bus Activity LED
Most computers have a disk drive activity light, usually an LED
(Light Emitting Diode) on the front panel. If you connect your sys-
tem's LED cable to the host adapter, the LED will light to indicate
SCSI bus activity.
Note: If you connect your computer's LED to the host
adapter, the LED no longer indicates non-SCSI disk
activity. So you may not want to use this feature if you
are running non-SCSI disk drives.
To connect the SCSI bus LED connector:
1Refer to your system's documentation to locate and unplug the
LED cable from the connector on the system board.
2Connect the LED cable to the SCSI activity LED connector (J1)
on the host adapter.
Note: On systems with a two position LED cable,
connect the LED cable to pins 1 (+) and 2 (-) of the
LED connector.
