Figure 2.7 Multiple Internal SCSI Devices Chained Together2.2.4.2 Making Activity LED Connection

Most PC cabinets are designed with a front panel LED to indicate bus activity. It may already be connected to an existing IDE controller. If you want, you can connect the LED to the SCSI LED connector.

Connect the LED cable to J3 on your SCSI host adapter, as shown in Figure 2.8.

The Busy LED connector J3 is not keyed. The J3 connector is a 4-pin one row right angle header. Some LED cables have only two wires. In this case, place the connector on one end of J3. If the LED does not light during SCSI bus activity, you may have to rotate the LED cable 180˚ on J3 or move it to the other end of the jack.
