Note: Notice that the components on a Ultra160 SCSI to PCI host adapter face the opposite way from non-PCI adapter boards you may have in your system. This is correct. The board is keyed to go in only one way.

Step 4. Secure the bracket with the bracket screw before making the internal and external SCSI bus connections. Figure 2.2 shows an example of how to insert your host adapter. All LSI Logic Ultra160 SCSI to PCI host adapters require a PCI slot that allows bus master operation.
