Installing any of these host adapters in your PCI/PCI-X/PCI Express system allows you to connect up to 15 SCSI devices per channel over a SCSI bus. The LSI20320L-R is designed with a bracket that is suitable for low profile applications.

To achieve Ultra320 SCSI performance, you must connect only

Low Voltage Differential (LVD) devices to the host adapter. If you connect single-ended (SE) devices and LVD devices, the entire bus drops to the lower SE speed, limiting bus performance to Ultra SCSI.

The Ultra320 SCSI host adapters support all major operating systems (OS), such as Windows (NT 4.0, 2000, 2003, and XP), Linux, NetWare, UnixWare, SCO OpenServer 5.x, and Solaris SPARC. Other software support includes SureLINK™ Domain Validation, which ensures

data integrity by intelligently testing the SCSI interconnect before completing negotiation.

The Ultra320 SCSI host adapters utilize Fusion-MPT™ architecture for all major operating systems, which allows for thinner drivers and better performance.

1.2 Quick Host Adapter Installation

Use these quick installation steps if you have installed computer add-in boards before and connected devices to them. For more detailed instructions and guidance, refer to Section 2.1, “Installing Your Ultra320 SCSI Host Adapter,” on page 2-2.

To install an Ultra320 SCSI host adapter, follow these steps:

Step 1. Turn off and unplug the computer.

Warning: Be sure to disconnect the computer’s power before you remove the cover and install the Ultra320 SCSI host adapter. Failure to do so may result in exposure to shock, electrical hazards, and/or mechanical hazards.

Step 2. Open your computer cabinet by removing its cover.
