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.

MXP909 PXIe module User’s Guide – Dolphin Interconnect Solutions Page 7
Airflow - Operating Environment
To maximize lifetime for the product and maintain the warranty, please honor the specified operating temperature, and make sure
the specified air flow is present.
TIP: After installing the Dolphin eXpressWare board management software, you can use the tool dis_diag to determine the actual
board temperatures.
Cable Connections
The MXP909 module is designed to support both long and short PCIe copper cables as well as PCIe active optical cables (AOC).
The MXP924 cable ports are compliant to the SFF-8644 industry specification and supports PCIe cables compliant to the PCIe
External Cabling Specification 4.0. Two x4 cables are needed for full PCIe x8 connectivity. (Ports P3 and P4 are unused)
PCI Express 4.0 Cables
When used with cables compliant to the new PCIe External Cable standard 4.0, the MXP909 module will transmit a CMI Reset
message downstream. The module can be connected to a MXP924 module in Target mode or any PCIe device compliant to the new
cable standard.
CMI Functionality
The MXP909 module BMC firmware release 2.4 and newer supports the following CMI operations when used with PCIe 4.0 cables:
•Publishes card and CMI status information in readable memory map
•Supports sending CMI reset, wake and power status messages
•Supports receiving indicators (LED/messages).
Active Optical PCIe Cables (AOC)
Dolphin offers active optical PCIe fiber cables up to 100 meters for the MXP909. CWAKE and CPOWERON is not supported using
standard PCIe AOC cables.

MXP909 PXIe module User’s Guide – Dolphin Interconnect Solutions Page 8
Installation
Step 1 - Unpack board
The MXP909 module module is shipped in an anti-static bag to prevent static electricity damage. The module should only be
removed from the bag after ensuring that anti-static precautions are taken. Static electricity from your clothes or
work environment can damage your MXP909 module or other PXIe components. Always wear a grounded anti-static
wrist strap while the MXP909 module is removed from the anti-static bag until it is properly installed in the PXIe
chassis.
Unpack the MXP909 module from the anti-static bag using proper anti-static procedures.
Step 2 - Configure the Board for Proper Operation
Set the DIP switch settings for proper operation depends on the firmware. Please refer to the section Configuration and DIP
Switches on page 10 for details.
Step 3 - Ensure proper Airflow
Please pay proper attention to ensure the selected server / slot position provides the minimum required airflow.
TIP: Immediately after software installation, please use the dis_diag tool to verify the temperature. If the chip temperature
reported by dis_diag exceeds 95°C, it is strongly recommended to improve the airflow.
Step 4 - Install the MXP909 module
Before installing the module, make sure you are properly grounded to avoid static discharges that may destroy your computer or
the PXIe module. Ensure you are properly grounded before opening your PXIe chassis or the anti-static bag
containing the MXP909 module. Please follow your PXIe chassis manual on how to install a PXIe System switch
module.
The MXP909 PXIe module supports PCI Express Gen1, Gen2, Gen3 and Gen4 backplanes. Please review the list of supported and
approved PXIe chassis
Step 5 - Installing and Removing the Cable
Installing and removing cables should be done with the PXIe chassis powered off.
Connecting the Cable
Please carefully install the cable connector into the connector housing on the MXP909 module. Cable port 1 is located at the top of
the face plate bracket. To install the cable, match the cable house with the connector on the MXP909 module. Use even pressure
to insert the connector until it is secure. Adhere to ESD guidelines when installing the cables to ensure you don’t damage the board.
Computer cables should always use strain relief to protect the connected equipment from excessive force on the cable. This is
especially important for cables between racks.
Cable stain relief
Strain-relief on the PCIe cables are important to protect the PCIe card from fatigue loading and damages. The cable should be
mechanically connected to the rack or cabinet. This is especially important for long heavy cables and cables going between cabinets
and racks.
Supported cable lengths
The MXP909 module supports both copper and active optical PCIe cables (AOC). Maximum lengths between two modules can be
found in Table 1 below. The maximum distance may change when connecting to other PCIe products.

Firmware Upgrade
The MXP909 module design uses a Board Management Controller (BMC) to implement the PCIe CMI protocol, reset and other
maintenance functions. Dolphin may from time to time publish updated firmware for the BMC, card configuration and the PCIe
switch.
WARNING: Please note that standard Microsemi tools (ChipLink) cannot be used to upgrade the firmware as this will violate the
warranty. Please contact Dolphin for instructions on how to upgrade the MXP909 module firmware.
Note: Please consult the MXP909 module Firmware Release Note for details on supported configurations.
Identifying the PXIe module
The module has a label-sticker with the serial number in the format ‘MXP909 PXIe module-YY-ZZZZZZ’, where YY denotes the
revision (e.g. BB) and ZZZZZZ denotes the serialized production number (e.g. 012345) –this whole string makes up the serial
number of the module (i.e. MXP909 module-CC-012345).
You can also get this information using lspci in Linux:
