A 32-bit slot should be used. The LSI21003 will work in a

64-bit slot, but only 32 bits are used. The host adapter requires a PCI slot that allows bus master operation. See Figure 2.2 on page 2-6.

Step 6. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use.

Save the bracket screw for securing the installed board.

Step 7. Carefully insert edge connector J1 of the host adapter into the PCI slot. Make sure the edge connector is properly aligned before pressing the board into place. See the example in Figure 2.2.

Note: You may notice that the components on the PCI Host Adapter face the opposite way from those on other non-PCI plug-in boards you have in your system. This is correct, and the board is keyed to go in only one way.

Step 8. Secure the board with the bracket screw before making the internal and external SCSI bus connections (see Figure 2.2).

Step 9. If you are connecting any internal SCSI devices, plug the end of an appropriate internal SCSI ribbon cable into the connector that provides the performance/features your system needs (see Figure 2.1 on page 2-5).

Make certain you match pin 1 on both connectors. Chain your internal devices on this cable.

Step 10. Connect the LED cable to J6 if desired.

This is designed to drive the front panel LED found on most PC cabinets to indicate activity on the SCSI bus. See Table 3.8 for the signal name and pin numbers for the LED interface.

Step 11. Make all external SCSI bus connections.

Step 12. Terminate the SCSI bus.

Step 13. Set SCSI IDs as required.

You must not have duplicate SCSI IDs.

Step 14. Replace the cabinet cover.

Step 15. Refer to the PCI Storage Device Management System SDMS

4.0User’s Guide (or the guide for the software that you will use) to load the driver software for your particular operating system.
