8 Troubleshooting Checklist If a problem occurs during installation, check these items first: s Are the power cables and SCSI interface cables properly connected? Connect internal devices to your computer's power supply; plug external device power cables into a grounded line power outlet. Follow the instructions in the hardware documentation. s Is the host adapter firmly seated and secured in a 16-bit expansion bus slot? s Is pin-1 orientation maintained throughout the SCSI bus? s Is each SCSI device, including the host adapter, set to a unique SCSI ID? s Is SCSI termination set correctly? 9 Host Adapter Switches If you have a Plug and Play system, you do not need to change any of these switch settings. However, the settings are listed in the table below for your reference (*=default setting; off=open).
