LSI Ultra320 Figure 2.1 Hardware Connections for the Host Adapter

Caution: You must touch a grounded metal surface before handling the host adapter because static charges on your body can damage electronic components. Handle plug-in boards by the edge; do not touch board components or gold connector contacts. LSI Logic recommends that you use a static ground strap.

Step 4. Remove your Ultra320 SCSI host adapter from its packaging and verify that it is not damaged.

Figure 2.1 shows the LSI22320 host adapter. The LSI20320 and LSI21320 Ultra320 SCSI host adapters are different in design and size. Refer to Chapter 3, “Ultra320 SCSI Host Adapter Characteristics,“for more details.

Step 5. Find an unused PCI-X or PCI slot.

Note: You can insert a 64-bit host adapter into a 32-bit slot if no 64-bit slots are available. However, if you do this, the data transmission rate is limited to standard PCI speed.
