•Getting started guide
PXIe System Switch Slot
The MXP924 must be placed in the PXIe system switch slot. The MXP924 supports PCIe Gen1, Gen2, Gen3 and Gen4 speeds. The
default PXIe backplane configuration is x16 + x8. The module will auto configure to the slot speed and width.
MXP924 Configuration
The MXP924 cable ports can either be configured as a single x4 / x8 / x16 PCIe target for connecting to a MXH932 configured for
host opeation or in daisy-chanin mode for connecting x4 / x8 to the host and a single x4 / x8 to a downstream MXP924.
The default DIP switch setting is transparent target x4 / x8 / x16 operations.
Thermal Shutdown
The MXP924 module includes an overtemperature overheat protection. The BMC will automatically shut down the MXP924 if a
PCIe switch temperature beyond 105°C (221°F) is detected. Similar, if an AOC is plugged in, the MXP924 module will automatically
shut down if the max operating temperature announced by the connected AOC is reached. Please consult the AOC data sheet for
details.
NOTE: The MXP924 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.

MXP924 User’s Guide – Dolphin Interconnect Solutions Page 7
PCIe Wake
The MXP924 supports PCIe Wake functionality. To utilize this functionality, you need to set the PXH924 DIP-SW2-2 / Enable Wake
to ON position and use PCIe 4.0 cables to connect to the MXH932. PCIe Wake must also be enabled in the System BIOS.
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 MXP924 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. Four x4 cables are needed for full PCIe x16 connectivity.
PCI Express 4.0 Cables
When used with cables compliant to the new PCIe External Cable standard 4.0, the MXP924 module will transmit a CMI Reset
message downstream. The module can be connected to a MXP924 in Target mode or any PCIe device compliant to the new cable
standard.
CMI Functionality
The MXP924 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 and receiving 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 MXP924 module. CWAKE and CPOWERON is not supported
using standard PCIe AOC cables.

MXP924 User’s Guide – Dolphin Interconnect Solutions Page 8
Installation
Step 1 - Unpack board
The MXP924 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 MXH924 module or your PXIe components. Always wear a grounded anti-static wrist strap while
the MXP924 is removed from the anti-static bag until it is properly installed in the PXIe chassis.
Unpack the MXP924 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 MXP924
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 MXP924. Please follow your PXIe chassis manual on how to install a PXIe System switch module.
The MXP924 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 MXP924 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 MXP924. 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 MXP924 supports both copper and active optical PCIe cables (AOC). Maximum lengths between two MXP924 modules can be
found in Table 1 below. The maximum distance may change when connecting to other PCIe products.

Operation
Configuration and DIP Switches
The MXP924 has two banks of 8 DIP switches. The default factory setting for the MXP924 is Transparent Target mode, single (up to
x16) link connection.
The MXP924 has DIP switches for setting special modes or operations, the meaning of each DIP switch depends on the loaded
firmware. Please carefully read the documentation shipped with the module before modifying any DIP switch settings. Please pay
close attention to ON and OFF positions written on the DIP switch.
DIP Switches

EEPROM and Firmware Upgrade
The MXP924 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, PCIe switch or EEPROM data for the card.
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 MXP924 firmware.
Note: Please consult the MXP924 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 ‘MXP924-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. MXP924-CC-012345).
You can also get this information using lspci in Linux:
Figure 3: Use Case C

MXP924 User’s Guide – Dolphin Interconnect Solutions Page 15
First, identify the devices for the Dolphin Host card:
Then run lspci and identify the module. It will show up as something like
Second, do
This shows the module as revision 0x4242 (hexadecimal values of the ‘BB’ letters in the ASCII table), with the production number
0x000000ff (00000255 in decimal).
