LSI 8751D Figure 2.8 SCSI LED Connector

Step 4. Most PC cabinets are designed with a front panel LED, which may already be connected to an existing IDE drive. Connect this LED cable to connector J4 on the host adapter, as shown in Figure 2.8. This allows the front panel LED to indicate activity on the SCSI bus. Connector J4 is not keyed. The orientation of the LED cable does not matter as long as all four pins are connected.

Connector J4

Some LED cables have only two wires. In this case, place the connector on one end or the other of J4. If the LED does not light during SCSI bus activity from this host adapter, you may have to rotate the LED cable 180° on J4.
