•
Which XMC slot and system will the card be installed in?
•
What is the speed and link width of the XMC carrier that the card will be installed in?
•
What is the operating environment for the Host computer?
•
What type and length of cables will be used?
•
How to ensure proper operational conditions, temperature and air-flow.
PCIe Slot Determination
The PXH820 supports PCIe Gen1, Gen2 and Gen3 speeds and x1, x2, x4, x8 using XMC connector P15 and x16 link-widths using XMC
connector P15+P16. The slot width and speed will affect the performance of the card. The card will auto configure to the slot
speed and width.
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.
PXH820 NTB Configuration
The PXH820 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 long cable tuning.
