SERVER-CLASS PCI EXPRESS BACKPLANE Trenton’s BPX6620 is a server-class backplane that supports a x8 PCIe link from a server-class PICMG 1.3 system host board (SHB) to the backplane’s PCI Express slot PCIe2. The PCI Express slot labeled PCIe1 is supported by a x4 link from a Trenton IOB31 expansion board. A server-class SHB provides three PCI Express links that drive the three PCI Express-to-Dual PCI-X bridge chips.

SHB SLOT Accepts an SHB Express (PICMG® 1.3) compliant (server-class) processor such as Trenton’s current NLT, NLI, SLT or SLI system host boards.

PCI EXPRESS SERIAL SLOTS PCIe2 is a x16 mechanical slot connected to the SHB with a x8 PCI Express link. PCIe1 is a x8 mechanical slot driven by a x4

0.855

Note: Connectors are populated based on model. Some holes are common to both hole patterns.

PCI EXPRESS SERIAL SLOTS (continued) PCI Express link from the PCIeS expansion slot. In order to use the PCIe1 slot a Trenton IOB31 I/O expansion board must be used on the server-class system host board. The IOB31 enables communication between the SHB/IOB31 and the PCI Express option card in slot PCIe1. PCI-X PARALLEL BUS SLOTS The ten PCI-X slots on the BPX6620 are connected to the SHB via three PCI Express links that drive three PCI Express-to-PCI-X bridge chips. Two bridge chips provide 64-bit/100MHz PCI-X channels that support slots C1 through F2. One bridge chip supports two 64bit/133MHz PCI-X channels that supports slots A1 and B1. PCI-X and universal (i.e. 5V/3.3V combo or 3.3V only) PCI option cards may be used and the bridge chips will throttle-down the bus interface speeds to match any universal PCI or PCI-X card with an interface bus speed less than 100MHz or 133MHz.

OPTIONAL USB 2.0 INTERFACES

CONNECTING POWER

The SHB Express specification defines optional I/O routings from the SHB to the backplane. Trenton’s BPX6620 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. Server-class system host board support for the USB port connections to a backplane is optional. Refer to the SHB OPTIONAL BACKPLANE I/O SUPPORT TABLE below for an explanation of the backplane I/O capabilities supported by Trenton’s PICMG 1.3 Server-class SHBs or contact Trenton for additional information and SHB product updates.

The combination of new power supply technologies, soft-power control signals available via the Advanced Configuration and Power Interface (ACPI) now supported by PICMG 1.3 SHBs and auxiliary power connectors on PICMG 1.3 backplanes that deliver all of the SHBs power to the edge connectors are requiring a different approach to connecting system power. 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, performance-based processor SHBs like the Trenton NLT. The ATX/EPS and +12V power connectors on the BPX6620 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.

OPTIONAL ETHERNET INTERFACES Trenton’s BPX6620 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. 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 Ethernet interface implementation method for details. The SHB OPTIONAL BACKPLANE I/O SUPPORT TABLE explains the backplane I/O capabilities supported by Trenton’s PICMG 1.3 System Host Boards.

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:

POWER CONNECTORS The BPX6620 backplane is available with power connectors suitable for use with either an ATX or EPS power supply.

EXTENDED-CURRENT TERMINAL BLOCKS 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.

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 BPX6620 backplane if the +5V AUX LED is GREEN. If the system appears to be off and the+5V AUX LED is GREEN then you need to remove or turn-off the incoming power to the system power supply.

AUXILIARY POWER CONNECTOR The +12V power connector on the BPX6620 routes 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.

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 according to unique system design requirements. For more information refer to the Appendix B (Power Connection) and Advanced Setup BIOS sections of any Trenton Technical Reference Manual for server-class system host boards such as the Trenton NLT, NLI, SLT or SLI.

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.
