Settings in SCSI Setup
SCSI is the abbreviation for
The onboard ultra-wide SCSI controller (host adapter) is the interface between the
internal bus (PCI bus) and devices with SCSI interfaces (SCSI devices).
The onboard ultra-wide SCSI controller is a PCI chip which uses Bus Master technology.
This allows your SCSI controller to independently manage data transfer between your
SCSI peripherals and the computer system memory, without requiring the involvement of
your computer system CPU (Central Processing Unit).
All the information you require to install the SCSI Utility Software (e. g. drivers for MS-
DOS, Windows 3.x) is contained in the User Guide for the SCSI Utility Software EZ-
SCSI.
Details of how you install and operate your SCSI device may be found in the associated
Manual.
Setting SCSI addresses (IDs)
Each device which is connected to the ultra-wide SCSI controller must be set to a
separate SCSI address (ID 0 through ID 15).
The ultra-wide SCSI controller has ID 7. ID 7 has the highest priority, SCSI-ID 0 has the
lowest. The priority of the remaining IDs, in descending order, is 15 to 8.
Ensure that each SCSI device is assigned it's own address.
Ê
Details how you set the SCSI address of your SCSI devices may be found in the
associated manual.
Connecting SCSI devices
SCSI devices and controllers are connected together via a common cable (SCSI bus).
The termination (terminating resistors) must be enabled (or installed) on the last device
connected to the SCSI cable. The termination must be disabled (or removed) from all
other SCSI devices.
How you activate or deactivate the termination of the SCSI devices, see description of
your SCSI devices.
Be sure the ends of the SCSI bus are correctly terminated.
Ê
Connect the SCSI devices to the SCSI connector on the system board by means of
Ê
the SCSI cable.
Only single-ended SCSI devices may be linked to the ultra-wide SCSI
i
controller. Most SCSI devices meet this requirement. If you are in any doubt,
contact your sales office or customer service.
How you install internal devices in the system unit and connect them to the power supply
is described in the Operating Manual or Technical Manual for your Server in the chapter
"System unit" (paragraph "Installing a disk drive").
Further information is provided in the descriptions of your SCSI devices.
