Introduction
This chapter provides a product description of the StorageWorks SWXOR Series 600 MB, dual-speed,
CD-ROM drives. It also identifies the various models and their storage subsystem configurations.
1.1 Product Description
The dual-speed, SWXOR series CD-ROM (Figure 1–1) is a low-profile, 600 MB,
compact, storage device compatible with StorageWorks storage subsystems. The drive is
capable of audio playback, has audio line outputs, and a headphone jack. It uses the
SCSI-2 (small computer system interface) bus, and is designed to operate with all
StorageWorks storage subsystems. The drive normally serves as the primary load device
for operating systems, applications, documents, and integrated video/audio products.
NOTE
The audio capability of the CD-ROM disk drive is included in
the hardware and is controlled by the host.
The SWXOR drive series is packaged in an industry standard 5.25-inch form factor
referred to as a StorageWorks Building Block (SBB). The dual speed CD-ROM is
available in four base configurations as described in Table 1–1.

Model Description
SWXOR-BA Single drive CD-ROM SBB.
SWXOR-BB CD-ROM upgrade kit for the SWXOR-BA.
SWXOR-BC CD-ROM upgrade kit for Desktop Expansion Unit.
SWXOR-BD Triple-drive CD-ROM SBB (Tri-Pack).
1.1.1 Model SWXOR-BA
The SWXOR-BA CD-ROM drive configuration is packaged in an industry standard
5.25-inch SBB and is capable of housing two identical dual-speed, low-profile, CD-
ROM drives. The SWXOR-BA model of the SBB contains a single drive as shown in
Figure 1–1.

1.1.2 Model SWXOR-BB
The SWXOR-BB model consists of a CD-ROM upgrade kit for the half-populated
5.25-inch SBB. The kit contains all of the components necessary to convert the
SWXOR-BA single drive SBB to a dual-drive device (not shown).
1.1.3 Model SWXOR-BC
The SWXOR-BC configuration consists of a drive upgrade kit for the StorageWorks
Desktop Expansion Unit. This kit is used to upgrade the right slot of the desktop
expansion unit from a 3.5-inch SBB to a 5.25-inch, low-profile CD-ROM.
Figure 1–2 shows the desktop expansion unit with the SWXOR-BC installed.
1.1.4 Model SWXOR-BD
The last model in the dual-speed, CD-ROM series is the SWXOR-BD referred to as a
"tri-pack". It consists of three low-profile drives mounted in a 5.25-inch SBB carrier
(Figure 1–3). The SWXOR-BD is installed in the StorageWorks deskside expansion
storage pedestal.
