System Cabling A-3
Standard Configuration
Your system is cabled using a single channel on-board IDE Controller and dual channel
on-board Adaptec 7899 SCSI Controller.
on-board Adaptec 7899 SCSI Controller.
The on-board IDE controller supports the standard internally mounted CD-ROM as its
master device. If only one device is on a channel connector it must be set as the master
device.
master device. If only one device is on a channel connector it must be set as the master
device.
The AIC 7899 contains two independent SCSI channels that share a single PCI bus
master interface. Each channel is capable of operations using either 8- or 16-bit SCSI
providing 160 MB/s (Ultra-160/M) or 80 MB/s (Wide Ultra2) throughput. If your
system includes the hot-swap hard disk drive bay, channel A attaches to an Ultra-160/M
SCSI backplane that supports up to six 160/M SCA drives. If your system includes the
standard hard disk drive bay, channel A attaches directly to a maximum of four 160/M
non-hot-swap drives. Controller B can be used to support SCSI devices in the
removable media bays. A 68 pin to 50 pin converter is also available to be used when
installing SCSI narrow devices.

Figure A-1 illustrates a system that includes the hot-swap hard disk drive bay. Referring
to the Figure A-1 below, a 68-pin Ultra-160/M SCSI interface cable (K) is connected to
the SCSI connector (J) on the middle right edge of the system board. This cable
connects to the rear of the hard disk drive's SCSI backplane (L).
