Expansion module
Figure 21 shows the IOM used in supported DS Series expansion enclosures for adding storage. Ports A/B/C ship
configured with 12Gb/s HD mini-SAS (SFF-8644) external connectors. Within 2U enclosures, the top slot for
holding IOMs is A and the bottom slot is B. The face plate detail of the expansion canister shows the module
aligned for use in A. This orientation also applies to canister insertion into either IOM slot located on the D3284
enclosure rear panel.
