BPG6714 |PICMG 1.3|PCI EXPRESS BACKPLANE| SMALL FORM FACTOR

Description

The BPG6714 is a small form factor PICMG® 1.3 backplane supports one PICMG 1.3 graphics-class SHB, one x16 PCI Express® slot driven with a x16 PCIe link and a x8 PCIe slot driven with a x4/x1 PCIe link from the SHB via the PCI Express expansion slot. The BPG6714 also features one 64-bit/133MHz PCI-X and two 64-bit/100MHz PCI-X option card slots. The PCI-X slots can also support universal PCI option cards.

ETHERNET INTERFACES

Trenton's BPG6714 backplane supports the optional Ethernet routing feature of the SHB Express (PICMG 1.3) specification. One 10/100/1000Base-T Ethernet RJ-45 connector (P13) is available for use on the backplane. Data communication performance of the backplane's Ethernet interfaces depends on the Ethernet controller hardware and configuration on the system host board.

Consult your SHB’s Ethernet interface implementation method for details.

I/O INTERFACES

Trenton’s BPG6714 supports two USB 2.0 headers  (P11 & P12) capable of providing up to four USB 2.0 backplane interfaces.

POWER INDICATORS

Surface-mount LEDs provide a convenient visual check for +5V, -5V, +5V AUX*, +12V, -12V and +3.3V power connection and status.

*CAUTION: Never install or remove the SHB or any option card from any backplane segment if the +5V AUX LED for the segment is GREEN. If the system appears to be off and the +5V AUX LEDs are GREEN, you need to remove or turn off the incoming power to the system power supply.

POWER CONNECTORS

The standard BPG6714 backplane is available with a low-profile right-angle power connector suitable for use with either an ATX or EPS power supply. An optional BPG6714 is available with straight-in or vertical power connectors. Using straight-in power connectors may interfere with a full-length option card placed in the SLTB1 slot.

The +12V power connector on the BPG6714 route auxiliary power to the SHB’s edge connectors. This new capability of PICMG 1.3 compliant SHBs and backplanes eliminates the need for auxiliary power connections on the system host board.

OPTION CARD SLOT DETAILS

PCI Express Slots
PCIe1 – x8 mechanical   /  x4 or x1 electrical link from SHB via IOB31
PCIe3 – x16 mechanical /  x16 electrical link directly from SHB

Note:  An MCG-series SHB provides a x4 PCIe link to slot PCIe1 and a TQ9, TML or T4L provides a x1 link

PCI-X/PCI Slots
SLTA1 – PCI-X, 64-bit/133MHz
SLTB1, SLTB2 – PCI-X/PCI, 64-bit/100MHz

Note: PCI-X/PCI slots support PCI-X and universal PCI option cards, (i.e. 5V/3.3V combo or 3.3V only). The bridge chip will throttle-down the bus interface speed to match any card that has a speed capability less than the supported bus interface speed of a specific PCI-X backplane slot.

See mechanical layout for detailed slot routing information.

MISCELLANEOUS BACKPLANE INFORMATION

Connecting Power

A new approach is required to connect system power due to the combination of new power supply technologies and the soft-power control signals available via the Advanced Configuration and Power Interface (ACPI). ACPI signals are now supported by PICMG 1.3 SHBs and backplanes. Auxiliary power connectors located on the PICMG 1.3 backplanes now deliver all of the power directly to the edge connectors of the SHB.

Auxiliary power connectors on the backplane are provided to help improve system Mean Time To Repair (MTTR). All power can be delivered to the SHBs via the board's edge connectors. Trenton's PICMG 1.3 SHBs and backplane SHB edge connector slots have ample power pins available to meet the power demands of high-performance dual processor SHBs. The ATX/EPS and +12V power connector on the BPG6714 backplane also have an ample number of power pins available to meet these demands. The system designer needs to be aware of the potential power demands of the entire system including the particular SHB to ensure that both the power supply and the power connectors in the cable harness can safely deliver the necessary power to drive the entire system.

Specific implementations of ACPI signals, ATX/EPS power supply type and the operating system software will determine the specific connection method for the power supply. For example the use of the Power Good (PWRGD), Power Supply On (PSON#), Five Volt Standby (5VSB) and the Power Button (PWRBT#) ACPI or soft power control signals require the following connection method:

ACPI signal usage is optional and may be turned off using the SHBs BIOS and/or signal jumpers. Specific power connections and BIOS parameters will differ depending on unique system design requirements. Refer to the Appendix B (Power Connection) and Advanced Setup BIOS sections found in the Technical Reference Manual for your specific Trenton system host board for more information.
