2.3.2 Connecting the LED Cable
Most computer cabinets have a front panel LED. When properly connected, the front panel LED lights when there is activity on the SCSI bus.
Connect the LED cable to connector J5 on the host adapter, as shown in Figure 2.8. Connector J5 is not keyed.

LED Connector J5
Left two pins are for Channel A
Right two pins are for Channel B
The orientation of the LED cable does not matter as long as all four pins are connected. If the LED does not light during SCSI bus activity from this host adapter, you may have to rotate the LED cable connector 180° on J5.
If your LED cable has only two wires, place the connector on one end or the other of J5. If the LED does not light when there is SCSI activity, move the connector to the other half of J5.
