Modules in a Single-Controller Configuration
This section shows how to replace modules in a single-controller configuration (see

only the controller, and replacing only the cache module. To upgrade a
single-controller configuration to a dual-redundant controller configuration, see
Chapter 5.

CAUTION: In a single-controller configuration, always shut down the subsystem
before removing or replacing any modules. Otherwise, data loss might occur.
For fiber optic cables without extender clips, thin needle-nose pliers must be used to
remove the cable from the controller without potentially damaging the cable (see
Figure 4–3).
