The MXP924 PXIe Switch PCIe cable adapter card is designed to create a flexible and scalable PXIe fabric solution. Combined with the PCIe Host card MXH932, the MXP924 enables servers and embedded systems to connect to PXIe systems utilizing full PCIe Gen4 wire speed. Multi-chassis configurations can be set up by daisy chaining several MXP924 boards or connecting two MXP924 directly to a MXH932.
PCI Express Gen 4.0
The MXP924 is designed for PCIe Gen 4.0 link speeds in the backplane and via the front panel PCIe cable port. It will auto negotiate to the highest speed supported (PCIe Gen4 - Gen1) by each component connected to individual port. This allows you to mix various generation of equipment without scarifying performance between high speed components.
PCIe Cable ports
The MXP924 switch has a quad SFF-8644 PCIe cable connectors to allow connectivity to external servers and IO devices. The cable port can be used as two independent x8 links or one x16 link. Each SFF-8644 connector has a protected 3.3V supply to support up to four PCIe Gen4 AOCs. The MXP924 is carefully designed for maximum copper cable lengths. Fiber optics extends this distance to 100 meters. More info on cable alternatives for the MXP924 switch.
The MXP924 follows the PXISA PXIE-1 rev 2.3 and PXISA PCIE-5 Hardware specification 1.1. The default backplane configuration is PCIe x16 +PCIe x8. Please contact Dolphin for other options.
The eXpressWare software distribution adds a PXI System Library integration (PXI Software Specification Revision 2.5) which allows software like Keysight IO Suite to discover and enumerate a number of PXI chassis and the 3rd party expansion boards in the chassis if MXH924 is installed in the chassis system slot.
Support for the MXH924 was introduced with eXpressWare 5.19.2. The software for the MXP924 must be installed on a host also having the MXH932 card installed. Please select and install the Board Management Package option with the installer to install the PXI System Library.
