SCSI Troubleshooting Checklist
The AIC-7896 SCSI controller has been tested for compatibility with a wide range
of SCSI devices. Most problems that occur during installation result from errors
in preparing and connecting devices on the SCSI bus.
Answer these questions first if a problem occurs during installation:
•
Are the power cables and SCSI interface cables properly connected?
Connect internal SCSI devices to your computer's power supply. Connect the
power cables of external SCSI devices to a grounded line power outlet.
Follow the instructions in the computer and SCSI device documentation.
•
Is pin-1 orientation maintained throughout the SCSI bus?
•
Are the PCI bus and slot parameters set correctly in your computer's Setup
program?
The PCI bus is designed to assign IRQ, port address, and BIOS address
settings automatically to the SCSI controller. But you may need to assign
some of these values manually in the Setup program.
•
Is each SCSI device, including the SCSI controller, set to a unique SCSI ID?
•
Is SCSI termination set correctly?
If your problem is still not resolved, continue with the next section.
