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.

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 cables 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.
