System Cabling Configurations C-5
Standard and Optional Hard Disk Drive Bays
SCSI Bus Cabling Configuration
The optional SCSI hard disk drive bay available for your system provides
storage for five additional SCSI hard disk drives.
If you order a system with the optional SCSI hard disk drive bay installed, the
system is pre-cabled at the factory (see Figure C-2" Standard and Optional Hard
Disk Drive Bays Cabling Configuration".)
If you are adding the optional SCSI hard disk drive bay you must install, cable,
and configure your system for this additional bay. Refer to "Installing an
Optional SCSI Hard Disk Drive Bay" in Chapter 4.
The on-board Ultra 160/m SCSI controller 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 is used to
support SCSI hard disk drives in the standard SCSI hard disk drive bay.
Controller B is used to support additional SCSI hard disk drives in the optional
SCSI hard disk drive bay.
Figure C-2 illustrates the Standard and Optional SCSI Hard Disk Drive Bays
bus cabling configuration. For standard SCSI hard disk drive bay cabling, see
the previous subsection "Standard Cabling Configuration".
The optional SCSI hard disk drive bay (A) has a 68-pin Ultra-160/m SCSI
interface cable (B) connected to the second SCSI connector (C) on the system
board. This cable connects to the rear of the optional hard disk drive's SCSI
backplane (D).
