Specifications
BP 1/1/2/4/4

PCI-X/PCI BUS SLOTS
Provides eleven PCI Local Bus slots which support PCI Local Bus option cards; seven of these PCI slots also support PCI-X option cards, which must be either +3.3V or universal option cards. The backplane's PCI-X bridges automatically detect the following option card parameters:
    Option card type -- PCI or PCI-X
    Architecture -- 32-bit or 64-bit
    Bus speed -- 33MHz, 66MHz, 100MHz, or 133MHz
The backplane also determines the speed at which the segment is capable of running without violating loading specifications. The auto-detection feature helps ensure stable system behavior and prevents board damage.


SBC SLOT
Accepts a PICMG® 1.0 compliant processor. The backplane supports new PCI-X compatible processors and legacy processors that support +3.3V signaling. Chassis Plans' XPT single board computer is an example of a processor or SBC that is PCI-X compatible; Chassis Plans' SLE, ULE and XPI are legacy SBCs that support +3.3V signaling.

PRINTED CIRCUIT LAYERS
The backplane is an eight-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, +12V, -12V and +3.3V power connections.
POWER CONNECTORS
The standard AT power connection is available through a 12-pin .156 MTA connector. Power connection for +3.3V is available through a 12-pin .156 MTA connector or an ATX connector (optional).

AUXILIARY POWER CONNECTOR
Additional power capacity is available through a .156 MTA connector.

EXTENDED-CURRENT CONNECTORS
Optional extended-current connectors provide additional power capacity for power-intensive applications -- up to 60 Amps of +5V plus 60 Amps of +3.3V.

PCI-TO-PCI BRIDGE
The PCI-to-PCI bridge supports the PCI Local Bus 2.1 specification. The BP1/1/2/4/4 backplane has bus mastering capabilities on all four PCI Local Bus Slots.

PCI-X BRIDGE
The PCI-X-to-PCI-X bridge eases the transition to PCI-X by supporting the PCI Local Bus as well as enabling 64-bit PCI-X architectures capable of running at speeds up to 133MHz at transfer rates up to 1GB/s. The bridge chip allows concurrent operations on both buses and is fully compliant with the PCI-X Addendum to the PCI Local Bus Specifications Revision 1.0 and the PCI Local Bus Specification 2.1.
