The Terminator is currently at the very end of the cable and the last drive is connected in the available slot next to it beside the other. There is no port at the end of the cable past the term

Browse All TopicsI install the scsi card and originally the Dell computer came with only one scsi ultra 160 (Fujitsu man3184mp) drive installed on the ribbon cable which has two scsi connectors and a terminator at the end. When I leave one drive in, it works fine but when I set the second drive to ID1 or any other scsi ID, both don't work. Dell set the original jumpers as follows jumpers #23 shorted to 21, 19 shorted to 17, 1 shorted to 2. I have attached a PDF for the jumper settings. T hank you for your assistance

According to the jumpers set on the disks, the terminator power isn't set (jumper 23 - 24 would set the terminator power, but it seems the point 23 is shorted to 21 with the jumper, so it is just a "reserve" jumper the way it is set).
Is this a server where the drives are attached through a backplane, or are they directly connecting to the SCSI cable? If backplane, have you checked whether it has any additional connections or jumper? Have you tried another port?
The drives are attached to an adpatec ultra 160 card. Both were originally supplied in the Dell workstation computer and I have tried to do is connect a second drive to its cable. A single drive works normally on it and the second drive, all I have done is set the ID to a different one then the first and since doing that, both fail. When I take the second drive off, drive one begins to work again. The bus cable from the card has two slots for the drives and at the very end of the cable (about 1/2 inch from the last slot) is a terminator. Do I need to allow terminator power via jumper?

The terminator should be set for only one of the drives, that one which is at the end of the cable.
