System Cabling A-3
Standard Configuration
Your system is cabled using a dual channel on-board IDE Controller
and an on-board Symbios Logic SYM53C875 SCSI Controller. The on-
board IDE controller supports the internally mounted CD-ROM as its
first (master) device and an optional IDE device as its second (slave)
device. The SCSI controller attaches to a 68-pin 16-bit (wide) SCSI
connector interface and is capable of supporting a maximum of four 1-
inch high SCSI hard disk drives or three 1.6-inch high SCSI hard disk
drives. Also, a 3.5-inch diskette drive is installed in all systems and
interfaces separately to the system board.
Referring to the "IDE Disk System Cable Configuration" Figure, your
system can be cabled using the on-board dual enhanced IDE controller.
This controller has two connectors (primary and secondary) on the
system board, each connector supporting a first (master) and a second
(slave) device. This provides support for the internally mounted IDE CD-
ROM, an optional tape, and up to three internally mounted IDE hard
disk drives. An IDE cable (K) connects the secondary IDE connector to
the CD-ROM as its master device (I) and an optional IDE device as its
slave device (J). Another IDE cable (O) connects the primary IDE
connector to the optional first hard drive (HD1) as its master device (M)
and the optional second hard drive (HD2) as its slave device (N).
As an option, the on-board SCSI controller can be used to control a
SCSI tape drive. In this case, a SCSI cable (D) connects the wide SCSI
connector to the optional SCSI tape drive (B) via a narrow SCSI to wide
SCSI adapter (C). The tape drive SCSI address assignment is 2. SCSI
termination must be installed in the last SCSI drive of the daisy chain
cabling. Since the tape is the only SCSI device, the termination resistors
(A) are installed in the tape drive.
When adding or removing IDE devices, consider the following:
The system board supports a primary and secondary IDE channel
connector. Each of these supports two devices, for a total of four IDE
devices.
A first (master) device and a second (slave) device are supported on
both the primary and secondary IDE channel connector.
The device configuration, master versus slave, is determined by
jumpers on the devices. Cable Sense (CS) device configuration is not
supported.
If only one device is on a channel connector it must be set as the
master device.
