Pre-Installation Questions
Certain steps should be taken prior to installing the MXH930. You should determine the following configuration requirements.
•Which PCIe slot and system will the card be installed in?
•What is the speed and link width of the slot that the card will be installed in?
•What is the operating environment in which the card will be installed?
•What type and length of cables will be used?
•How to establish proper operational conditions, temperature, and airflow.
PCIe Slot Determination
The MXH930 supports PCIe Gen1, Gen2, Gen3 and Gen4 speeds and x1, x2, x4, x8 and x16 link-widths. The slot width and speed
will affect the performance of the card. The card can be physically installed in a x4, x8 or x16 connector. The card will auto
configure to the slot speed and width.
•Install the board in a slot connecting directly to the CPU for optimal shared memory performance.
•Install the board behind a PCIe switch in the IO system for optimal PCIe peer to peer performance (e.g. between GPUs,
FPGAs)
TIP: After installing the eXpressWare software, run the “sisci_benchmarks” benchmark suite to verify the expected performance.
Please contact Dolphin support if you need assistance to reach the expected performance.
MXH930 NTB Configuration
The MXH930 has a DIP switch bank to control the main configuration of the card. The DIP switch labeled SW1 can be found close to
the upper edge of the board. The default DIP switch setting is single link x16 operations. Alternative configuration settings are two
x8 links or four x4 links.
Airflow - Operating Environment
To maximize lifetime for the product and maintain the warranty, please honor the specified operating temperature, and make sure
the specified airflow is present. Special care should be considered when the MXH930 is used in office type cabinets with poor
cooling in combination with other high energy consuming PCIe devices, e.g. not active cooled GPUs:
Operating Temperature: 0°C - 55°C (32°F - 131°F), Airflow: 350 LFM (Preliminary)
Operating Temperature with AOC: TBD
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.
Cable Connections
The MXH930 is designed to support both long and short copper cables as well as active optical cables (AOC).
The MXH930 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.
Active Optical Cables (AOC)
Dolphin offers active optical PCIe fiber cables up to 100 meters for the MXH930 cards. Please contact Dolphin for more information
on long distance fiber optic performance and availability.

MXH930 User’s Guide – Dolphin Interconnect Solutions Page 7
Installation
Step 1 - Unpack board
The MXH930 card is shipped in an anti-static bag to prevent static electricity damage. The card 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 PCI Express adapter card or your PC. Always wear a grounded anti-static wrist strap while opening
the PC and when the MXH930 is removed from the anti-static bag.
Unpack the MXH930 from the anti-static bag using proper anti-static procedures.
Step 2 - Change PCIe Bracket if necessary
The MXH930 package includes a standard and low-profile PCI Express bracket. By default, the standard height bracket is installed
on the board. If you need to replace the mounted bracket with a low-profile bracket, carefully unscrew the two mounting screws to
remove the full height bracket. Save the two mounting screws and replace the bracket with the low-profile bracket. Use the two
mounting screws to install the low-profile bracket. The screws should be carefully tightened but be careful not to over-tighten.
Make sure you are properly grounded to avoid static discharges that may destroy the adapter card before performing this
procedure.
Step 3 - 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 9 for details.
Step 4 - 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 5 - Install the Adapter Card
Before installing the adapter card, make sure you are properly grounded to avoid static discharges that may
destroy your computer or the adapter card. Ensure you are properly grounded before opening your
computer or the anti-static bag containing the MXH930. Please follow your computer’s or expansion
chassis manual on how to install a PCI Express card.
The MXH930 Adapter card can be installed into any PCI Express x16 slot. The MXH930 supports PCI Express Gen1,
Gen2, Gen3 and Gen4 signaling. NOTE: A Gen4 slot is recommended as it typically doubles the performance
compared to a Gen3 slot. The MXH930 is an x16 card, so maximum performance will only be attained if the slot
provides full electrical x16 signaling.
The MXH930 supports hosts using either spread spectrum or constant frequency clocking. The card implements
clock isolation.
Step 6 - Installing and Removing the Cable
Installing and removing cables should be done with both host and expansion system powered off. Please contact
your Dolphin representative if you intend to continuously connect and disconnect the PCI Express cables.
Connecting the Cable
Please carefully install the cable connector into the connector housing on the MXH930 adapter card. Cable port 1
is located at the top of the PCIe bracket, ref Figure 1: Full length PCIe bracket to the right. To install the cable,
match the cable house with the connector on the MXH930 adapter card. 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. Note that for wider than x4 connections, the
same cable-ports (i.e. port 1 to port 1, port 2 to port 2 through port 4) should be used on both host and target for
each individual cable, to ensure that the cards properly link up as x8 or x16.
Figure 1: Full
length PCIe
bracket

MXH930 User’s Guide – Dolphin Interconnect Solutions Page 8
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 Cables
The MXH930 supports both copper and PCIe active optical cables (AOC) available from Dolphin. Maximum lengths between two
