SERVER-CLASS PCI EXPRESS™ BACKPLANE

PCI EXPRESS SERIAL SLOTS

Trenton’s BPX6610 is a server-class backplane that supports six PCI Express™, four 64-bit/66MHz PCI-X/PCI and two 64bit/100MHz PCI-X/PCI option card slots.

Option card slots PCIe1 and PCIe2 are driven by x8 PCI Express links directly from a server-class system host board. PCIe2 is a x16 mechanical slot capable of supporting x16, x8, x4 or x1 PCI Express option cards. PCIe3 through PCIe6 are x8 mechanical slots and each slot is driven by a x4 PCI Express link from the PCI Express fan out switch. The fan out switch is driven by a x4 PCI Express link from the server-class SHB.

SHB SLOT Accepts an SHB Express™ (PICMG® 1.3) compliant (serverclass) processor such as a Trenton NLT/NLI, SLI/SLI or MCXseries system host board.

PCI-X PARALLEL BUS SLOTS

CONNECTING POWER

The six PCI-X slots on the BPX6610 are connected to the SHB via a x4 PCI Express link delivered from the PCI Express fan out switch to the PCI Express-to-PCI-X bridge chip. The bridge chip provides a 64bit/66MHz PCI-X channel to support option card slots SLTA1 through SLTA4 and a 64-bit/100MHz PCI-X channel to support slots SLTB1 and SLTB2. These slots support PCI-X and universal PCI option cards i.e., 5V/3.3V combo or 3.3V only. The bridge chip will throttledown the bus interface speeds to match any universal PCI or PCI-X card with an interface bus speed less than 66MHz or 100MHz.

A new approach is required to connect system power due to the combination of new power supply technologies and the softpower 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.

OPTIONAL USB 2.0 INTERFACES The SHB Express specification defines optional I/O routings from the SHB to the backplane. Trenton’s BPX6610 takes advantage of this new specification feature by providing two USB 2.0 headers capable of providing up to four USB 2.0 backplane ports.

OPTIONAL 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 are available for use on the backplane. The SHB OPTIONAL BACKPLANE I/O SUPPORT TABLE explains the backplane I/O capabilities supported by Trenton’s PICMG 1.3 System Host Boards.

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.

Auxiliary power connectors on the backplane are provided to help improve system Mean Time To Repair (MTTR). All power can be delivered to the SHB 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 highperformance dual-processor SHBs. The ATX/EPS and +12V power connectors 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:

AUXILIARY POWER CONNECTOR 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.

EXTENDED-CURRENT TERMINAL BLOCKS Two extended-current terminal blocks provide additional power capacity for power-intensive applications -- up to 80 Amps of +12V, 120 Amps of +3.3V and 80 Amps of +5V.

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 the BPX6610 backplane if the +5V AUX LED is GREEN. If the system appears to be off and the+5V AUX LED is GREEN, you need to remove or turn off the incoming power to the system power supply.

PRINTED CIRCUIT LAYERS The backplane is a six-layer, .080” thick board with three separate signal layers: +5V/+12V, +3.3V and ground. Multi-layer backplane construction provides excellent noise immunity.

Power On Switch Normally Open Momentary

ACPI signal usage is optional and may be turned off using the SHB’s 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.
