Fast-Wide SCSI-2 Hard Drives

The Integrated Fast-Wide SCSI-2 Controller is compatible with industry
standard Fast-SCSI-2 and Fast-Wide SCSI-2 peripherals. It supports up to
seven internal or external single-ended SCSI-2 devices (asynchronous,
synchronous or fast synchronous).
Compaq ProLiant 5000 models support high-performance 4.3-GB and 2.1-GB
Fast-Wide SCSI-2 hard drives, and will support 9-GB Fast-Wide SCSI-2 hard
drives when they become available.
Integrated Fast-Wide SCSI-2
Connector and Cable
The Integrated Fast-Wide SCSI-2 Controller includes both an external Fast-
Wide SCSI-2 connector and an internal Fast-Wide SCSI-2 connector on the
same bus. A terminated SCSI cable is attached to the internal SCSI connector.
If you add SCSI devices, be certain this cable still is terminated.
In non-array server models, this cable connects to one end of the drive cage
backplane board. The internal SCSI bus continues along the backplane and
through another cable to the CD-ROM player. The bus ends at a terminator
beyond the CD-ROM player.
If you add a SMART-2 Array Controller, you must replace the internal SCSI
controller-backplane connection with a link from the SMART-2 controller to
the backplane. The CD-ROM player then connects directly to the integrated
Fast-Wide SCSI-2 controller. Ensure that this cable still is terminated beyond
the CD-ROM drive. Follow the detailed instructions in the Compaq SMART-2
Array Controller User Guide that accompanies the new controller.
Do not operate the system without the internal SCSI cable connected, even if
no devices are attached to it. If the cable is removed, a POST error code will
be generated and the system will not boot.
