2.2.8 Mezzanine Card
The DM-SV01 server is compatible with OCP Mezzanine Card 2.0 Design Specification. The mezzanine
card is a network interface card (NIC) which is installed on two connectors on the top of the
motherboard, near the front panel. The image below shows the positioning of the mezzanine card in
the DM-SV01 motherboard.

The DM-SV01 mezzanine card slot is compatible with PCIe Gen3 x16. Lower PCIe bus speeds and
widths are also acceptable, due to the intrinsic capacity of the PCIe bus of automatic switching down
its speed and lane width to comply with the endpoint device capability.
The mezzanine card is seen by the operating system as a standard network PCIe device. The
mezzanine card also provides the NCSI (Network Controller Sideband Interface), which is used as an
inband management interface to access the BMC.
The image below shows an example of a mezzanine card that can be used in the DM-SV01 server.
