Matrox Radient eCL-DF, Installation And Hardware Reference, Page: 21 / 96

Installing your Matrox Radient eCL board 21
Matrox Radient eCL might drop frames if there are not at least 8 active lanes on
the PCIe connector to the Host (for example, if the board is connected to a x8
PCIe connector that has only four active lanes
*
). Verify with your motherboard
manufacturer to find out whether your motherboard works efficiently with a x8
PCIe board, such as Matrox Radient eCL.
If installing Matrox Radient eCL-QB or eCL-DF, the slot immediately to the right
of the selected slot must also be free. Matrox Radient eCL-QB and eCL-DF have
a double bracket to accommodate the connectors on their main board and
expansion module. Only the main board plugs into its slot’s connector; the
expansion module attaches only to the back of the computer’s chassis.
If you need to install the cable adapter bracket of your Matrox Radient eCL board,
you need an additional slot. This slot need not be adjacent to the Matrox Radient
eCL board. In addition, the cable adapter bracket does not plug into the slot’s
connector; it attaches only to the back of the computer’s chassis.
❖
Note that the external auxiliary I/O connectors on the cable adapter bracket
are panel mount connectors. So if you don’t want to occupy an entire slot to
access the two connectors, you can punch out two holes in the computer chassis
for these connectors, and then screw the connectors in the holes.
*. After installing the board, you can verify in software the number of PCIe lanes that are
currently active using the MIL-Lite function MsysInquire() with
M_PCIE_NUMBER_OF_LANES.
