System Cabling Configurations C-3
Standard Cabling Configuration
The server unit is cabled using a single channel on-board IDE Controller, a
single channel on-board Adaptec 7880 SCSI controller, and a dual channel on-
board Adaptec 7899 SCSI controller.
The on-board IDE controller supports the standard internally mounted CD-ROM
as its master device.
The AIC 7880 provides a single SCSI channel PCI bus master interface and is
capable of operating using either 8- or 16-bit SCSI providing 80 MB/s (Ultra-
Wide) throughput. As implemented on the system board the AIC7880 controller
is used to support SCSI devices in the 5 1/4-inch removable media bays and to
SCSI hard disk drives connected to the external SCSI connector port.
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) throughput. As implemented on the
system board controller A attaches to the standard Ultra-160/m SCSI backpanel
that supports up to five 160/m SCA drives. Controller B attaches to the optional
Ultra-160/m SCSI backplane that supports up to five additional 160/m SCA
drives. A 68 pin to 50 pin converter is also available to be used when installing
narrow SCSI devices.
A 3.5-inch floppy diskette drive is also installed in the system and interfaces
separately to the system board.
Referring to Figure C-1 a 68-pin Ultra-160/m SCSI interface cable (L) is
connected to the SCSI connector (M) on the system board. This cable connects
to the rear of the standard hard disk drive's SCSI backpanel (I). Another 68-pin
Ultra-160/m SCSI interface cable connector (K) is available for cable
connection to the optional hard disk drive SCSI backpanel.
The IDE interface cable (D) is connected to the IDE connector (E) on the system
board. This cable connects to the rear of the internally mounted CD-ROM drive
(C).
Optional internally mounted SCSI removable media devices (A) may be
connected to the SCSI controller connector (N) with Ultra-Wide SCSI interface
cable (B). This cable also connects to an external SCSI connector (O) located on
the rear of the server chassis.
The diskette drive interface cable (G) is connected to the diskette drive
connector (H) on the system board. This cable connects to the rear of the
internally mounted diskette drive (F).
