Standard Configuration

System Cabling
Your system is cabled using the on-board IDE controller
and the on-board Adaptec 7880 wide SCSI controller.
The on-board IDE controller supports the internally
mounted CD-ROM as its first (master) device and an
optional internally mounted tape drive as its second
(slave) device. The on-board Adaptec 7880 wide SCSI
controller is used to control the four hard disk drives.
Also, a 3.5-inch diskette drive is installed in all systems
and interfaces separately to the system board. Figure A-
1 is a diagram of the standard cabling and Figure A-2
illustrates the internal cable routing for this
configuration.
The wide SCSI interface cable is connected to the SCSI
connector on the top edge of the system board (see
Figure A-1, J). This cable connects to the rear of the
hard disk drives. The last hard disk drive on the SCSI
cable must have it's internal SCSI terminators or
terminator jumper installed.
The IDE interface cable is connected to the IDE
connector towards the top edge of the system board (see
Figure A-1, U). This cable connects to the rear of the
internally mounted CD-ROM as its master device (see
Figure A-1, R). An optional internally mounted tape
drive can be connected to the IDE controller as its slave
device (see Figure A-1, S).
The on-board Adaptec 7860 narrow SCSI controller is
used to control up to two optional internally mounted
removable media peripherals. The narrow SCSI
interface cable is connected to the SCSI connector above
the wide SCSI connector on the system board (see
Figure A-1, D). This cable connects to the rear of the
SCSI removable media peripherals (if present). The last
drive on the daisy chain cable must have it's internal
SCSI terminators installed. If your server doesn't have
any SCSI removable media peripherals, the cable is not
used and the narrow SCSI controller is terminated
using the SCSI termination resistors (see Figure A-1,
E).
