MXP909 PXIe Module High Level Specification
The MXP909 is a PXIe peripheral Transparent PCIe x8 Gen4 cable module and supports PCIe downlink connections to other PXIe
chassis with a MXP924 or any other compliant PCIe transparent target device. The MXP909 supports PCIe Gen1, Gen2, Gen3 and
Gen4 speeds and x1, x2, x4 and x8 link-widths. The module will operate at the highest common speed shared between the slot and
the card (Gen4) and the widest common link-width up to x8.

Getting started guide
PXIe Slot
The MXP909 module can be placed in any compliant PXIe slots. The MXP909 supports PCIe Gen1, Gen2, Gen3 and Gen4 speeds.
The default PXIe backplane configuration is x8. The module will auto configure to the slot speed and width.
MXP909 Module Configuration
The MXP909 cable ports can either be used as a single x4 / x8 or dual x4 port configuration.
The default DIP switch setting is transparent single x4 or single x8 operations. The lower two connectors marked P3 an P4 is not in
use.
Thermal Shutdown
The MXP909 module includes an overtemperature overheat protection. The BMC will automatically shut down the MXP909 module
if a PCIe switch temperature beyond 105°C (221°F) is detected. Similar, if an AOC is plugged in, the MXP990 module will
automatically shut down if the max operating temperature announced by the connected AOC is violated by 15°C (59°F). Please
consult the AOC data sheet for details. Please consult the AOC data sheet for details.
NOTE:
The MXP909 module link LEDs will start flashing yellow when a PCIe switch temperature of 95°C (203°F) is reached or when
the AOC reports a temperature 5°C (41°F) lower than the max operating temperature.
NOTE:
The automatic shutdown can be disabled by setting DIP switch SW2-4. Prior to disabling the automatic shutdown, please
ensure you have established proper airflow.
