Installing Enclosures in Multiple Racks
This section describes a connection configuration where the enclosures are installed in multiple racks.
When installing enclosures in multiple racks, obtaining extra extension cables for these connections between
the racks is required.
When installing all the items included in the same node within the same expansion rack, the backend cable will
not cross between the racks even when installed on multiple racks. However, an extension cable is necessary for
a connection between the drive enclosures installed to the upper part and the controller enclosures.

ple Racks)
