BPX6610 |PICMG 1.3| PCI EXPRESS BACKPLANE

Description

Trenton's BPX6610 is a 14-slot form factor server-class backplane supports one PICMG® 1.3 server-class SHB, one x16 PCI Express® slot and one x8 PCIe slot each driven with a x8 PCIe link from the SHB. Four x8 PCIe slots are also available with each one driven by a x4 link from the 24-lane PCI Express fan out switch. The BPX6610 also features two 64-bit/100MHz PCI-X and four 64-bit/66MHz PCI-X option card slots.

ETHERNET INTERFACES

Trenton's BPX6610 backplane supports the optional Ethernet routing feature of the SHB Express (PICMG 1.3) specification. Two 10/100/1000Base-T Ethernet RJ-45 connectors (P13 and P14) are 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 BPX6610 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 BPX6610 backplane is available with low-profile right angle and vertical power connectors suitable for use with either an ATX or EPS power supply.

The +12V power connectors on the BPX6610 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.

Two extended-current terminal blocks provide additional power capacity for power-intensive applications -- up to 80 Amps of +12V, 80 Amps of +3.3V and 40 Amps of +5V.

OPTION CARD SLOT DETAILS

PCI Express Slots
PCIe1 – x8 mechanical   / x8 electrical link directly from SHB
PCIe2 – x16 mechanical / x8 electrical link directly from SHB
PCIe3, PCIe4, PCIe5, PCIe6 - x8 mechanical  / x4 electrical link from SHB via PCIe switch

PCI-X/PCI Slots
SLTA1, SLTA2, SLTA3, SLTA4 – PCI-X/PCI, 64-bit/66MHz
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 BPX6610 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.
