General Description
This chapter illustrates and describes, in general terms, the BA370 enclosure and
Model 2200 enclosure subsystems and their major components, plus connectors,
switches, and LEDs.
Refer to the Fibre Channel switch documentation that came with the switch kit for
specifics about how the switch operates. Refer to the KGPSA PCI-to-Fibre Channel
Host Adapter User Guide for information about the adapter that connects the
subsystem to the host.
Subsystem Components—Exploded Views
This section illustrates the various subsystem enclosures, components, and specific
attributes of each component. Spare part numbers are included as a convenience,
under two part numbering systems (the 6–3 system and the 2–5–2 system).
