The PXH810 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.
The PXH810 card can be installed in any PCI Express compliant x8 or x16, Gen1, Gen2 or Gen3 slot.
Electrically, the PXH810 supports PCIe Gen1, Gen2 and Gen3 speeds and x1, x2, x4, and x8 link-widths.
The card will operate at the highest common speed shared between the slot and the card (Gen3) and the widest
common link-width (x8).
For best performance, we recommend a PCI Express Gen3 x8 or Gen3 x16 slot.
All DIP switches should normally be left in the factory default setting. More details on DIP switch settings can be
found on page 10 in this document.
PXH810 Operating Modes
The Dolphin PCI Express PXH810 card is a PCIe NTB (Non-Transparet Bridge) adapter card. The card
functionality is controlled by the MODE SELECT DIP switch labeled SW1 that can be found close to the upper
edge of the board. The main configuration options are found in the table below. The default DIP switch setting
will be appropriate for most uses. One exception is that when a fiber is in use, one card
needs to have the TARGET-DIP set and needs to be connected correctly to the
corresponding end of the fiber.
Note: 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 card is removed from the anti-static bag.
Max 2 meter
copper. Contact
Dolpin for
information on
longer cables.
The PXH810 requires an x8 iPass™ or standard PCI Express cable. A single x8 cable is used to connect to
another PC with a PXH810 card or an IXS600 8 port switch.
To install the cable, match the x8 cable with the connector on the PXH810 adapter card. Use even pressure to
insert the connector until it is secure. Adhere to ESD guidelines when installing the cable to ensure you don’t
damage the board. The PXH810 supports both copper and active fiber cables. Details can be found in the table
below.
Using the PXH810 with Optical Fibers
The PXH810 card is compliant with active fiber optic cables from Samtec. On the fibers, the iPass-housing on
one end is marked HOST, and the other end is marked TARGET. Please set the TARGET-DIP on the PXH810
to ON on the card connected to the TARGET end of the fiber.
Dolphin Software
The Dolphin Express PXH810 adapter card is compliant with Dolphin’s extensive software package for the PX
product line. Please visit http://dolphinics.com/support/index_support_px.html to download the latest
documentation and software.
Dolphin provides software and documentation for several product families; please remember to select the PX product family before downloading.
The software download requires a password to log in. The password will automatically be emailed to you if you
follow the instructions found on the getting started guide bundled with the adapter card.
Please note that mixing IXH6xx and PXH810 cards in NTB mode is not yet supported by Dolphin software due to
implementation differences between the Avago and IDT NTB features. The PXH812 can connect to the IXH620
XMC card for transparent operation.
The PXH810 adapter supports the complete suite of Dolphin NTB software including Dolphin SuperSockets™,
optimized TCP/IP drivers, and SISCI embedded software.
Dolphin SuperSockets™ is a Berkeley compliant Sockets library, which provides socket latency below 1
microsecond and close to the wire speed streaming bandwidth for networked applications. SuperSockets™ is
currently available on Linux and Windows. It is a 100% transparent plug and play solutions for commercial and
embedded applications. More on SuperSockets™ can be found at http://www.dolphinics.com/products/dolphin-
supersockets.html
Dolphin’s optimized TCP/IP driver enables PCI Express to be used as a traditional 10G Ethernet / 40G Ethernet
replacement for things such as NFS sharing and legacy networking that does not need the low latency provided
by SuperSockets. The TCP/IP driver supports gateway functionality.
The SISCI software provides a well-defined, easy-to-use shared memory / reflective memory programming API
for PCI Express over cable. More on SISCI can be found at http://www.dolphinics.com/products/embedded-sisci-
developers-kit.html
More information about the software provided for the Dolphin PXH810 adapter cards can be found on

Picture 2: DIP Switch
The PXH810 has one bank of 8 DIP switches. The default factory setting for the PXH810 is NTB mode, short
cable.
The PXH810 has DIP switches for setting special modes or operations. Please carefully read the documentation
before modifying any DIP switch settings. Please pay close attention to ON and OFF positions written on the
DIP switch.
DIP Switch Bank – Configuration
The DIP switch on the PXH810 is used to configure the adapter card.
Please leave all undocumented DIP switches in the default position.
Note: Some DIP switch configuration options may be removed in the future versions. Please always consult the
user guide for details.
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 PXH810 is
removed from the anti-static bag.
Changing the PCI Express Bracket
The PXH810 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.
Installing 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 PXH810. Please follow your computer’s manual on
how to install a PCI Express card.
The PXH810 Adapter card can be installed into any PCI Express x8 or x16 slot. The PXH810 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. The PXH810 is an x8 card, so no additional performance can be
obtained by using an x16 slot.
The PXH810 supports hosts using either spread spectrum or constant frequency clocking. The card implements
clock isolation and will provide a high quality CFC CREFCLK signal on the cable.
Installing and Removing the Cable
The PXH810 supports PCI Express x8 Gen3 cables. Installing and removing cables should be done with both
upstream and downstream device powered off. The Dolphin SuperSockets™, TCP/IP drivers and SISCI fully
support hot plugging (i.e. installation and removal of cables while the system is running). Standard PCI Express
cables are not designed for a high number of installations and removals; the gold applied to the connector head
may wear out and cause loss of communication. Please contact your Dolphin representative if you intend to
continuously connect and disconnect the PCI Express cables.
Connecting the Cable
Please carefully install the PCI Express cable connector into the connector housing on the PXH810 adapter card
or IXS600 Switch box. 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.
Disconnecting the Cable
Please carefully pull back the thumb tab to release the cable from the connector house and pull back the cable.
EEPROM Programming
Dolphin may from time to time publish updated firmware. Current firmware is normally included in the Dolphin
software distribution and published on the web at www.dolphinics.com/support. Please consult the software
documentation for information on firmware upgrades or contact Dolphin support if assistance is required.
The card has a label-sticker with the serial number in the format ‘PXHXXX-YY-ZZZZZZ’, where XXX denotes the
card-type (e.g. 810), YY denotes the card revision (e.g. CC) and ZZZZZZ denotes the serialized production
number (e.g. 012345) – this whole string makes up the serial number of the card (i.e. PXH810-CC-012345).
With the DIS software installed and loaded, you can get this serial number with the dis_diag command:
The top of this output will show information about the card (example from a PXH810-card);
Adapter 0 > Type : PXH810
NodeId : 4
Serial number : PXH810-CC-000024
PXH chipId : 0x87b010b5
PXH chip revision : 0xCA
EEPROM version NTB mode : 0010
Card revision : CC
Topology type : Switch
Topology Autodetect : No
Number of enabled links : 1
PCIe slot state : x8, Gen3 (8 GT/s)
Clock mode slot : Port
Clock mode link : Global
Max payload size (MPS) : 128
Multicast group size : 2 MB
Prefetchable memory size : 256 MB (BAR2)
Non-prefetchable size : 64 KB (BAR4)
Here you will see the whole serial number string, as well as the decoded card-type and card-revision identifiers.
The ‘EEPROM version NTB mode’ may be of interest – this shows the firmware-version of the card.
You can also get this information without dis_iag (for instance when the drivers are not loaded or the card is in
transparent mode), using lspci in Linux:
First run lspci, and identify the card. It will show up as something like
02:00.0 PCI bridge: PLX Technology, Inc. PEX 8717 16-lane, 8-Port PCI Express Gen 3
(8.0 GT/s) Switch with DMA (rev ca)
02:00.1 System peripheral: PLX Technology, Inc. Device 87d0 (rev ca)
02:00.2 System peripheral: PLX Technology, Inc. Device 87d0 (rev ca)
03:00.0 PCI bridge: PLX Technology, Inc. PEX 8717 16-lane, 8-Port PCI Express Gen 3
(8.0 GT/s) Switch with DMA (rev ca)
04:00.0 Bridge: PLX Technology, Inc. PEX 8732 32-lane, 8-Port PCI Express Gen 3
(8.0 GT/s) Switch (rev ca)
Second, do an lspci –vvvv –s <device> , and look for the ‘Serial’ –string
# lspci -s 02:00.0 -vvv | grep Serial
Capabilities: [180 v1] Device Serial Number 00-00-44-45-00-00-05-48
This shows the card as revision 0x4445 (hexadecimal values of the ‘DE’ letters in the ASCII table), with the
production number 0x00000548 (001352 in decimal).
