2.3.2 Connecting the LED Cable
Most computer cabinets have a front panel LED. When properly connected,
the front panel LED lights up when there is activity on the SCSI bus.
Connect the LED cable to connector J5 on the host adapter, as
Figure 2.10 shows. Connector J5 is not keyed.
Figure 2.10 SCSI LED Connector
The orientation of the LED cable does not matter as long as all four pins
are connected. If the LED does not light up during SCSI bus activity from
this host adapter, you may have to rotate the LED cable connector
180 degrees on J5.
If the LED cable has only two wires, place the connector on one end or
the other of J5. If the LED does not light up when there is SCSI activity,
move the connector to the other half of J5.
