Adaptec 1520B User Guide - Page 1

Introduction This installation guide provides the instructions needed to install and use your new SCSI host adapter. Once you have performed the simple installation steps listed on pages 2 through 5, your host adapter and SCSI devices are ready for operation. We recommend that you keep this installation guide with your important computer documents. One of the benefits of SCSI is that you can connect as many as seven peripherals to your host adapter. If you are not connecting the full complement of seven peripherals during your initial installation, when the time comes to add another peripheral, this installation guide will help with that installation. Also, this installation guide includes information on the Adaptec SCSISelect™ configuration utility. After installation, you can use this utility to reconfigure your host adapter without having to reopen the computer or handle the card. LED Connector Connects to the computer's LED cable to display activity on the SCSI bus. Switch Block Controls host adapter BIOS and I/O port addresses in non-Plug and Play systems. Internal SCSI Connector Uses a 50-pin internal SCSI ribbon cable to connect internal SCSI devices. 123 4 Pin 1 Host Adapter BIOS PROM Provides booting capabilities from a SCSI hard disk drive. Also stores the onboard SCSISelect configuration utility. External SCSI Connector Uses 50-pin high-density external SCSI cables to connect external SCSI devices.
