Connectivity topology

The E1012 and E1024 support single and dual expansion module configurations. Standard models of the
E1012 and E1024 ship with one or two expansion modules (see Table 2). Single module configurations can
be upgraded to dual module configurations non-disruptively.
Each expansion module has two 6 Gb SAS x4 ports (Mini-SAS SFF-8088 connectors) labeled IN and OUT.
These ports are used for connections to a supported RAID adapter installed in a server and for daisy
chaining the E1012 and E1024 enclosures between each other. The external port on the RAID controller is
connected to the IN port on the expansion module, and the OUT port on the expansion module is
connected to the IN port on the expansion module in the adjacent enclosure and so on.
