1–4 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide
All of these elements (except the redundant power supply and the EMU) are essential
elements for normal enclosure operation. Without the EMU, the enclosure loses some
features and functionality, but data storage capabilities continue as normal. Any empty
element bay requires the installation of a blank assembly. Figure 1–3 identifies major
element locations within the enclosure.

NOTE:
Model 2100 enclosures support only two I/O modules; whereas Model 2200 enclosures
support all six I/O modules. For Model 2100 enclosures, a blank panel covers the four vacant I/O
module bays (see Figure 1–1).
Appendix C describes the recommended sequence to follow for preparing an enclosure for
use.
