Installation 

Step 1 - Unpack board 

 

The MXH932 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 MXH932 is removed from the anti-static bag. 
Unpack the MXH932 from the anti-static bag using proper anti-static procedures. 

Step 2 - Change PCIe Bracket if necessary 

The MXH932 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 11 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 MXH932

. Please follow your computer’s 

or 

expansion chassis manual on how to install a PCI Express card. 
 

The MXH932 Adapter card can be installed into any PCI Express x16 slot. The MXH932 supports PCI Express 
Gen1, Gen2, Gen3 and Gen4 signaling. NOTE: A Gen3 slot is recommended as it typically doubles the 
performance compared to a Gen2 slot. The MXH932 is an x16 card, so maximum performance will only be 
attained if the slot provides full electrical x16 signaling. 
The MXH932 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 MXH932 adapter card. Cable 
port 1 is located at the top of the PCIe bracket, ref  Figure 1 PCIe Bracket to the right. To install the cable, 
match the cable house with the connector on the MXH932 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
