SCSI Problems and Solutions

The AMM-1525M/1510M host adapters have been tested for com-
patibility with popular SCSI devices. Most problems that might
occur during installation can be traced to errors in preparing devices
on the SCSI bus.
The following sections should help you to solve any problems that
you may encounter. If you need additional help in getting the host
adapter running properly, information on contacting Adaptec Tech-
nical Support is included on page ii.

Troubleshooting Checklist

If problems occur, check these items first:
Be sure all cables are properly connected. Check both power
and SCSI interface cables. See Connecting SCSI Devices
(AMM-1525M/1510M Only) on page 2-10.
Connect internal peripherals to your computer's power sup-
ply; plug external peripheral power cables into a grounded
line power outlet. Follow the instructions in the hardware
documentation.
Be sure the host adapter is firmly seated and secured in the
expansion slot it is installed in. See Installing the Host Adapter
on page 2-8.
Check SCSI bus termination. The devices at the ends of the bus
must be terminated. See Terminating the SCSI Bus on page 2-14.
Be sure the SCSI devices and host adapter are each set to a
unique SCSI ID (0-7). See Setting SCSI IDs on page 2-15.
If you have installed more than one host adapter make sure
that each is set to a separate I/O port address and IRQ channel.
See Setting Jumpers on page 2-6.
