Figure 9 Cabling connections between the MSA 2040 controller and a single drive enclosure
The figure above shows examples of the MSA 2040 controller enclosure—equipped with a single
controller module—cabled to a single drive enclosure equipped with a single expansion module. The
empty I/O module slot in each of the enclosures is covered with an IOM blank to ensure sufficient air flow
during enclosure operation. The remaining illustrations in the section feature enclosures equipped with dual
IOMs.
IMPORTANT:
controller module must be installed in the upper slot, and an I/O module blank must be installed in the
lower slot (shown above). This configuration is required to allow sufficient air flow through the enclosure
during operation.
