Trenton Technology BPX6571 Server Class PCI Express Backplane

Trenton's BPX6571 is a server-class backplane that enables the maximum number of high-bandwidth; i.e x4 or greater, PCI Express links from the System Host Board to the backplane's PCI Express option card slots and devices.

Features:

• 19-slot from factor supports PCI-Express, PCI-X and PCI option cards
• One SHB Express (PICMG 1.3) System Host Board Slot
• One x16 and one x8 PCI Express Slot (mechanical)
• Sixteen PCI-X 64-bit/66MHz Slots
• Optional four USB 2.0 backplane I/O connections
• Optional two 10/100/1000Base-T backplane Ethernet ports
• ATX/EPS right angle power connectors

PCI Express Serial Slots

PCIE2 is a x16 slot connected to the SHB with a x8 PCI Express link. PCIE2 mechanically supports x16, x8, x4 and x1 PCI Express cards. PCIE1 is a x8 slot driven by a x4 link and supports x8, x4 and x1 PCI Express cards. The actual speed of a PCI Express connection to an option card slot is determined by the SHB's PCI Express link configuration and the auto-negotiation/link training features of PCI Express.

System Host Board (SHB) Slot

Accepts an SHB Express (PICMG® 1.3) compliant (server-class) processor such as Trenton Technology's NLT, NLI and future SLT, SLI system host boards.

PCI-X Parallel Bus Slots

The sixteen PCI-X slots on the BPX6571 are connected to the SHB via two x4 PCI Express links that each drive a PCI Express-to-PCI-X bridge chip. Each bridge chip provides two 64-bit/66MHz PCI-X channels to support option card slots A1 through D4. 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 66MHz.

Optional USB 2.0 Interfaces

The SHB Express specification defines optional I/O routings from the SHB to the backplane. Trenton's BPX6571 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. The Trenton NLT/NLI System Host Board supports two USB ports with a factory installed option. Please contact Sarsen Technology if you are interested in this optional NLT/NLI functionality.

Optional Ethernet Interface

Trenton's BPX6571 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.

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 BPX6571 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 Connections

The +12V power connector is a right angle connector on the BPX6571 used for routing 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.
