If you have problems, check these items first: s Are all SCSI cables and power cables properly connected? s Are all SCSI devices turned on? s Have you connected SCSI devices to more than two of the three SCSI Channel A connectors? If you connected devices to all three connectors, disconnect devices from one connector! s Is the Adaptec SCSI Card firmly seated and secured in the PCI/PCI-X expansion slot? s Is the PCI expansion slot compliant with PCI Rev. 2.1 or higher and does it support Bus Mastering? s Are all SCSI devices on each SCSI bus assigned unique SCSI IDs? s Is termination set correctly on all the devices? Note: If you have problems with a specific SCSI device when other connected SCSI devices are working correctly, please contact the manufacturer of the problem device for troubleshooting information.
