Installation
Step 1 - Unpack board
The PXH820 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 PXH820 is removed from the anti-static bag.
Unpack the PXH820 from the anti-static bag using proper anti-static procedures.
Step 2 - Configure the Board for Proper Operation
The PXH830 has one bank of 8 DIP switches. Set the DIP switch settings for the required NTB use case. The default factory setting
for the PXH820 is NTB mode, short cable, single (up to x16) link connection.

Step 3 - 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 PXH820. Plea
se follow your computer’s
or expansion chassis manual on how to install a PCI Express
card.
The PXH820 Adapter card can be installed into any XMC 1.0 compliant carrier card. The PXH820 supports PCI Express
Gen1, Gen2 and Gen3 signaling. NOTE: A Gen3 slot is recommended as it typically doubles the performance compared to
a Gen2 slot. Using the XMC P15 connector, the host link will be up to x8. The PXH820 card supports x16 host connections
using both P15 and P16.
The PXH820 supports hosts using either spread spectrum or constant frequency clocking. The card implements clock isolation.
To install the card:
1.
Ensure the PXH820 face plate is removed from the SFF8644 connector block.
2.
Carefully slide the connector side of the PXH820 card through the carrier card front panel cut out.
3.
Carefully align the XMC connectors to the connectors on the carrier card and push the PXH820 and the carrier card
together.
4.
Mount the 4 screws to fix the PXH820 card to the carrier card.
5.
Mount the PXH820 front panel face plate around the SFF-8644 connector block
–
align the LEDs and the holes in the face
plate. Fix the two screws.
Step 4 - Installing and Removing Cables
Installing and removing cables can be done while the systems are running. Hot plugging / removing cables are fully supported.
