The BPC7041 PCI Express Backplane

The BPC7041 PCI Express backplane is a passive backplane with no active components such as PCIe switches or bridges.  The BPC7041 is specifically designed for use with dual-processor single board computers like the BXT7059 or JXT6966 with the optional IOB33 and PEX10 modules installed on the SBC.

The PCI Express interfaces from the dual-processor SBC, as well as the PEX10 and IOB33, are used to provide direct PCIe SBC-to-I/O card communication links to all ten of the BPC7041 PCIe backplane slots.  Our SBCs support the PCIe auto-training function to ensure SBC-to-option card communications regardless of PCIe interface type or link width.  This SBC and backplane design maximizes system flexibility by enabling system support for standard PCIe 3.0, 2.0 or 1.1 option cards having x16, x8, x4 and x1 PCIe electrical interface link widths .

Key features of the BPC7041 PCI Express backplane include:

  • Designed to support dual-processor BXT7059 or JXT6966 SBCs
  • Takes full advantage of the direct PCIe linking capability of the Intel® Xeon® processors
  • Ten total PCIe option card slots available in PCI Express backplane applications
    • 5 – x4 PCI Express 2.0/1.1 electrical / x16 mech. connectors
    • 4 – x4 PCI Express 2.0/1.1 electrical* / x16 mech. connector
    • 1 – x4/x1 PCI Express 2.0/1.1 elect.# / x8 mech. connector
      *Requires PEX10 option on dual-processor SBC IOB3x on SBC – link width SBC dependent
  • Flexible system power connections and support for PICMG 1.3 backplane I/O
  • IOB33 and PEX10 PCIe link expansion slots
  • Long life cycle with 7+ year backplane availability
The BPC7041 PCI Express backplane is designed, manufactured and supported in the USA, and backed by a 5-year warranty.


Tech Specs

Model Number


Form Factor

14-slot form factor supports one JXT6966 PICMG 1.3 SHB and up to ten PCI Express option cards


Server or Graphics:  Nine PCIe x4 (x16 mechanical) plus one PCIe x1 (x8 mechanical) slots driven directly from the SHB.

Note 1: Optional IOB33 module required to provide a x1 PCIe electrical link to backplane slot PCIe5.  The x1 PCIe link width is established by the JXT6966 system host board.  Backplane slot PCIe5 is a PCIe 1.1 interface only.

Note 2: Optional PEX10 module provides PCIe Gen 2.0 links from processor two of the JXT6966 SHB to BPC7041 backplane slots PCIe1 through PCIe4.

Note 3: Backplane slot PCIe10 is a PCIe 1.1 slot only.

Note 4: Backplane slots PCIe1 through PCIe4 and PCIe6 through PCIe9 may operate as either PCIe 2.0 or PCIe 1.1 slots depending on the end point devices connected to these slots.

Card Slots

5 – x4 PCI Express 2.0/1.1 electrical / x16 mech. connectors
4 – x4 PCI Express 2.0/1.1 electrical* / x16 mech. connectors
1 – x4/x1 PCI Express 2.0/1.1 electrical# / x8 mech. connector

*Requires PEX10 option on SBC #From IOB3x on SBC / link width SBC dependent


Board dimensions: 12.3” x 12.9” with a minimum drive tower cut-out of 13.41 square inches

The nominal backplane thickness is 0.080”; however, the backplane mounting holes are recessed 0.018” on the bottom to provide an effective PCB thickness of 0.062” for use in the chassis design process.
