Product Information • SCX-PCIE • Secondary Backplane Controller

Adjacent Backplanes Coupled for a Maximum of 18 Peripheral Slots

The SCX-PCIE delivers PCI Express® links to any slot of a 1+8 secondary CompactPCI® Serial

backplane. Four peripheral card slots are connected as x4, sourced from the PEX8724 24-lane

PCIe® Gen3 switch; another 4 slots are wired to an optional PI7C9X2G606PR Gen2 switch for x1

links. With respect of peripheral card slots 4 and 5, please note the discontinuity here, due to

customers request. For a system with 4 peripheral card slots Gen3 x4 therefore a standard

secondary backplane with minimum 5 peripheral card slots would be required (or a 4 slot custom

backplane).

No other backplane high speed signal types than PCIe® are supported by the SCX-PCIE. For

peripheral cards which need Ethernet, USB and/or SATA in addition, please refer to the CPU

carrier Card resources (primary backplane).
