Chapter 5: Getting Started ● 24 Before You Begin ● Read the safety information on page 45. ● Familiarize yourself with your SCSI card's physical features (see page 13). ● Ensure that you have the proper cables for your SCSI card and disk drives (see page 22). ● If you have a low-profile computer cabinet, replace the original full-height bracket with the low-profile bracket supplied in the SCSI card kit. ● Handle the SCSI card by its bracket or edges only. Installing the Adaptec SCSI Card This section describes how to install your Adaptec SCSI card into your computer cabinet. ! Caution: Electrostatic Discharge (ESD) can damage your SCSI card. Handle the SCSI card carefully so that you do not expose it to static charge. 1 If you have a low-profile computer cabinet, replace the original full-height bracket on the SCSI card with the lowprofile bracket supplied in the SCSI card kit. 2 Turn off your system and disconnect the power cord. 3 Open the cabinet, following the manufacturer's instructions. 4 Insert the SCSI card into an available PCIe slot (compliant with PCIe rev. 1.0) and secure the bracket in the PCIe slot, using the retention device (for instance, a screw or lever) supplied with your system. 5 Install and connect any internal drives using the appropriate cable(s), then close the computer cabinet. Note: If you connect non-LVD/SE (Wide Ultra/Ultra) SCSI devices to the same SCSI channel as LVD (Ultra320, Ultra160 and Ultra2) SCSI devices, the data transfer rate for the LVD SCSI devices will drop to non-LVD/SE performance levels. To achieve maximum data transfer rates for the LVD SCSI devices, be sure to keep them separate. Connecting Disk Drives 1 Set the SCSI ID of each disk drive to a unique number between 0 and 15. The SCSI card is set to ID 7 by default. Although not recommended, you can change the SCSI card ID by using the SCSISelect utility (see page 34). Note: Do not change the SCSI card ID unless absolutely necessary. 2 Install a terminator (or enable termination) on the disk drive at the end of each cable, or the end of the cable itself.
