Functional Descriptions
This section covers functional descriptions of key parts and fea-
tures of the Genesis MP. For Removal and Replacement
Procedures, refer to Chapter 4 of this guide.
SCSI Interface
Genesis MP has two SCSI interfaces: the internal Fast SCSI-2
interface, and the internal/external standard SCSI interface. The
internal Fast SCSI-2 interface drives the internal hard disk and
CD-ROM.
The internal Fast SCSI-2 bus supports transfer rates up to 10
MB/sec. The internal/external SCSI bus supports transfer rates up
to 5 MB/sec.
The motherboard end of the internal SCSI bus is terminated by a
110 W passive terminator. This terminator is located on the main
logic board near the portion of the internal chassis connector that
contains the internal/external SCSI signals.
Termination of the drive end of the internal SCSI bus is accom-
plished by installing the internal drive at the last connector on the
internal SCSI cable, and enabling termination on that drive.
Hard Drives
DayStar currently provides several different drive configurations for
Genesis MP. These include single drive systems operating on the
motherboard SCSI interface, and multiple drive Fast and Wide
arrays using a high-performance PCI SCSI controller.
Additionally, users may install any kind of drive controller available
on the PCI bus (SCSI-3, FiberChannel, SSA). It is also possible to
configure a “software-only” disk array using the Fast SCSI-2 moth-
erboard interface.
For installation instructions refer to Chapter 3 of the Genesis MP
User Guide.
CD-ROM Drive
Genesis MP has a CD-ROM drive that supports worldwide stan-
dards and specifications for CD-ROM and CD-digital audio disks.
This tray-loading CD-ROM drive is located in the top 5.25˝ remov-
able media bay.
