Detailed Installation Procedure 2-13
Step 4. Most PC cabinets are designed with a front panel LED which
may already be connected to an existing IDE drive. You may
connect this LED cable to your SCSI host adapter, as shown in
Figure 2.8 . This connection causes the front panel LED to
indicate activity on the SCSI bus.
The LED connectors J4 and J7 (see Figure 2.1 ) are not keyed.
The orientation of the LED cable does not matter as long as all
four pins are connected.
Figure 2.8 SCSI LED Connectors
Some LED cables have only two wires. In this case, place the
connector on one end or the other of J4 or J7. 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 or J7.
See Table A.5 in Appendix A for connector pinout information.
