Host Interface
The DSI SS7MDL4 board has a x1 electrical, x4 physical PCI Express connector. It can be installed in x4, x8,
or x16 PCI Express slots.
Note:
The DSI SS7MDL4 board is a high performance densely packed low profile PCIe board supporting
high message rates. In achieving this performance, the board may dissipate up to 17W and this
must be taken into consideration when selecting both the host chassis and the PCI Express slot in
