one
of the following SCSI controllers:
■
PCI SCSI controller (on select models of the Compaq Deskpro
Workstation AP250)
■
An integrated Ultra3 SCSI controller that has one internal
connector on the system board and one external connector on the
rear panel (Compaq Professional Workstation AP550)
■
An integrated Dual Ultra3 SCSI controller with two independent

(Compaq Professional Workstation SP750)
SCSI Cables
Depending on your workstation model, the following three areas are
available for installing or connecting mass storage SCSI devices:
■
Removable hard drive cage (Compaq Professional Workstation
SP750 only)
■
Front drive bays
Using a SCSI Cable
The Compaq Professional Workstation SP750 ships with a Low
Voltage Differential (LVD) SCSI cable that supports up to five SCSI
devices: a maximum of three in the removable hard drive cage and two
in the front drive bay area.
The Compaq Professional Workstation AP550 ships with a multi-mode
SCSI cable that supports LVD or single-ended devices. The cable
accommodates up to three SCSI devices in the front drive bay area.
The Compaq Deskpro Workstation AP250 also ships with a multi-
mode SCSI cable that supports LVD or single-ended devices. The
cable accommodates up to three SCSI devices in the front drive bay
area. Some Compaq Deskpro Workstation AP250 models ship with an
internal SCSI drive preinstalled in the front drive bay area. You can
add additional high-performance SCSI drives using the external SCSI
connnector located on the rear panel of the workstation.
