BP6FS6605 |PICMG 1.3| PCI EXPRESS| SIX SEGMENT BACKPLANE

Description

The BP6FS6605 is a six-segment PICMG® 1.3 backplane supports up to six graphics- or server-class SHBs. Each System Host Board (SHB) segment contains a x16 PCI Express mechanical slot and three of the segments also have a x8 PCIe option card slot. The backplane is optimized to support SHBs with low-profile cooling solutions such as the Trenton TML, SLT or SLI system host boards.

ETHERNET INTERFACES

Trenton's BP6FS6605 backplane is available with an optional Ethernet fabric to enable the SHBs in each segment to share data and communicate information to and from the system host via the backplane's Ethernet hub port. The backplane's optional Ethernet hub switch makes this functionality possible. The Ethernet hub switch controls the SHB-to-SHB communication and the SHB's communication to the host system via the 10/100Base-T Ethernet port interface. This optional backplane capability requires that the SHB support the optional Ethernet interface routing to SHB edge connector C as defined in the PICMG® 1.3 or SHB Express™ specification. The Ethernet fabric on the BP6FS6605 backplane enables many system advantages in applications that require cluster computing.

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

POWER INDICATORS

Surface-mount LEDs provide a convenient visual check for +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

Each backplane segment provides soft control power circuitry to control the power-up and power-down sequences of each SHB segment. Connecting an independent power source to each segment maximizes the power control aspect of each backplane segment. The BP6FS6605 backplane allows segments to be powered individually or grouped together for the purpose of being powered by a single power source. Care must be used when grouping segments together to ensure that adequate power is provided and the desired power sequences are controlled. The BP6FS6605 backplane supports two backplane connector option types: ATX/EPS and terminal blocks.

Standard ATX/EPS Segment Power Connectors
In this configuration, each SHB segment is usually powered by a separate ATX or EPS power supply. A 24-pin vertical power connector in each SHB segment provides the interface to the segment’s power supply. Each segment also includes a +12V auxiliary power connector for routing the auxiliary power directly 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. The BP6FS6605 backplane power connectors used in the standalone configuration are suitable for use with either an ATX or EPS power supply.

Terminal Block Segment Power Connectors
The terminal block connectors enable each SHB segment or multiple segments to be powered by a +12V power source. The voltage regulator circuits in each SHB segment provide all of the required voltage levels for the SHB and option card slots. Using the terminal blocks is the recommended method for grouping together segments in order to drive multiple segments with a common power supply. (Note: grouping segments with the standard ATX/EPS power connectors is also allowed, but Trenton recommends using the terminal blocks for this type of multiple SHB segment power connection.) Each segment’s four-position terminal block provides additional power capacity and up to 80 Amps of +12V.

OPTION CARD SLOT DETAILS

Graphics-Class Configuration
In a graphics-class configuration of the BP6FS6605, the SHB slot in each backplane segment supports a graphics-class PICMG 1.3 system host board such as Trenton’s TML. Each graphics-class SHB segment supports the segment’s x16 PCI Express (PCIe) mechanical slot with a x16 PCIe electrical link from the SHB. There is one x16 PCIe mechanical slot for each SHB segment: PCIe1-2, PCIe2-2, PCIe3-2, PCIe4-1, PCIe5-1 and PCIe6-1.

Server-Class Configuration
In a server-class configuration of the BP6FS6605, the SHB slot in each backplane segment supports server-class PICMG 1.3 system host boards such as the Trenton SLT or SLI. Each server-class SHB segment supports the x16 PCI Express (PCIe) mechanical slot with a x8 PCIe electrical link from the SHB. SHB segments A1, A2 and A3 also feature a x8 PCIe mechanical slot. These slots are labeled PCIe1-1, PCIe2-1 and PCIe3-1 and are driven by an SHB’s x4 PCI Express link in both graphics-class and server-class configurations of the backplane

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 connectors on the B6FS6605 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.
