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.
