Cable Connections
The PXH812 requires an
x8 iPass™ or PCI Expr
ess standard cable. A single x8 cable is used to connect to a PXH812 card in
target mode, other compliant transparent I/O devices, or an IXS600 8 port switch in transparent mode.
To install the cable, match the x8 cable with the connector on the PXH812 board. Use even pressure to insert the
connector until it is secure. Adhere to ESD guidelines when installing the cable to prevent damage to the board. The
PXH812 supports both copper and active fiber cables. Copper cables up to 5 meters long and active fiber cables up to 100
meters long are supported at full Gen3 speed between PXH812 cards. Connectivity to other PCIe devices may require
special tuning for copper cables longer than 2 meters.
Connecting to a x4 Device
An x8 to x4 transition cable can be used to connect the card to PCI Express equipment having an x4 iPass connector.
Please contact Dolphin for more information.
Using the PXH812 with Optical Fibers
The PXH812 card is compliant with active fiber optic cables from Samtec. The fiber iPass houses are marked with Host or
Target. The Host side should be connected to the card configured to be the upstream transparent host. The iPass house
marked with Target should be connected to the downstream target adapter card.
Dolphin Software
Transparent mode (Host or Target operation) does not require any special software.
