PCI EXPRESS SERIAL SLOTS
The two PCI Express slots on the BPX3/8 backplane provide the mechanical connections between PCI Express option cards and a PICMG 1.3 system host board. The x8 slot mechanically supports x8, x4 and x1 PCI Express cards and the electrical interface between the slot and the SHB is a x4 PCI Express link. The x16 slot accepts x16, x8, x4 and x1 PCIe cards and has a x8 PCI Express electrical connection to the SHB. The actual PCI Express electrical configuration between the SHB and option card depends on the SHB's PCI Express link configuration and the auto-negotiation/link training features of PCI Express.

PCI-X BUS SLOTS
Provides eight PCI Local Bus slots which support PCI Local Bus option cards; four of these PCI slots also support PCI-X option cards, which must be either +3.3V or universal option cards

SHB SLOT
Accepts an SHB Express (PICMG® 1.3) compliant processor. Chassis Plans' NLT and NLI system host boards are examples of processors, SHBs or SBCs that are PCI Express compatible.

PCI EXPRESS-TO-DUAL PCI-X BRIDGES
The PCI Express-to-Dual PCI-X bridge eases the transition to PCI Express by supporting the PCI Local Bus as well as enabling 64-bit PCI-X architectures capable of running at speeds up to 66MHz. The bridge chip is fully compliant with the PCI-X Addendum to the PCI Local Bus Specifications Revision 1.0 and the PCI Local Bus Specification 2.2.

PCI-TO-PCI BRIDGE
The PCI-to-PCI bridge supports the PCI Local Bus Specification 2.2. The BPX3/8 backplane has bus mastering capabilities on the four PCI Local Bus Slots. These slots are +5V tolerant making them ideal for supporting legacy PCI option cards

POWER CONNECTORS
The backplane is available with an ATX or EPS power connector

AUXILIARY POWER CONNECTOR
A +12V power connector is also provided 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.

EXTENDED-CURRENT CONNECTORS
Optional extended-current connectors provide additional power capacity for power-intensive applications -- up to 80 Amps of +12V, 80 Amps of +3.3V and 40 Amps of +5V.

PRINTED CIRCUIT LAYERS
The backplane is a six-layer, .062" thick board with three separate signal layers: +5V, +3.3V and ground. Multi-layer backplane construction provides excellent noise immunity.

POWER INDICATORS
The power indicators provide a convenient visual check for +5V, -5V, +5V AUX,+12V, -12V and +3.3V power connections.
