Chapter 1 Installation and Setup Although the HP Ultra3 SCSI Host Bus Adapter is a 64-bit PCI host bus adapter, it also works in a 32-bit PCI slot. When installed in a 32-bit PCI slot, the host bus adapter automatically runs in the slower 32-bit mode. This installation guide explains how to: • Install the HP Ultra3 SCSI host bus adapter • Set up SCSI devices • Connect SCSI devices Where to Obtain Installation Instructions Complete installation and removal instructions can be found in both of the following sources: • The HP Server Operations and Maintenance Guide, on the HP Startup CD-ROM shipped with your HP Server, has a complete chapter on installing and configuring the HP Server. • The HP Server Operations and Maintenance Guide for your HP Server can be viewed and printed from the official HP Server web site: http://welcome.hp.com/ country/us/eng/support.htm Bus Segments on the HP Ultra3 SCSI Host Adapter The HP Ultra3 SCSI host bus adapter features technology that ensures you get the best performance from your Ultra3 and Ultra2 SCSI devices by electronically isolating the primary LVD/SE segment from the secondary SE segment on the SCSI bus. This allows the HP Ultra3 SCSI host bus adapter to support newer Ultra3 and Ultra2 SCSI devices at speeds up to 160 MBytes/sec on the primary LVD/SE segment while at the same time supporting Ultra (legacy) devices at speeds up to 40 MBytes/sec on the secondary SE segment. The following figure shows the two SCSI segments. 2
