After completing the installation of your internal and external SCSI devices that connects to an
Adaptec AHA-1542s SCSI adapter, you find that none of the devices works. Which of the following
should you do first to try and fix the problem?

A.
Disconnect all devices and start over.

B.
Remove the adapter and replace with a new one.

C.
Change the SCSI ID’s

D.
Enable termination on the adapter.

Explanation:
Some adapter cards like the Adaptec AHA-1542s still need to have terminators installed. If you set
up both internal and external devices and none of them work, try enabling termination on it to see
if that fixes the problem.
Incorrect Answers:
A: Disconnecting all the devices and starting over will not solve the problem as you need to enable
termination on the adapter.
B: You do not have to remove and replace the adapter; you need to enable termination on it to
make it function properly.
C: Changing the SCSI IDs will not solve the problem when all that is necessary is to enable
termination on the adapter to enable proper functioning of the SCSI devices.Reference:David
