PCI EXPRESS SERIAL SLOTS
The two PCI Express slots on the BPX3/14 are x8 slots
that mechanically support x8, x4 and x1 PCI Express
cards. PCI Express option card slot (PCE1) is driven
directly by the SHB via a x4 PCI Express link between
the card slot and the SHB slot. The actual speed of
the PCI Express connection between the SHB and option
card slot PCE1 depends on the SHB's PCI Express link
configuration and the auto-negotiation/link training
features of PCI Express. In order to use the second
PCI Express slot (PCE2) a Chassis Plans IOB31 I/O expansion
board must be used on Chassis Plans' NLI or NLT system host
board. The IOB31 provides a x4 PCI Express electrical
connection to the PCE2 slot that enables communication
between the SHB/IOB31 and the PCI Express option card.
PCI-X BUS SLOTS
Provides fourteen PCI Local Bus slots which support
PCI-X and universal PCI 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 bridges ease 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 133MHz. The bridge chips are fully compliant
with the PCI-X Addendum to the PCI Local Bus Specifications
Revision 1.0 and the PCI Local Bus Specification 2.2.
USB 2.0 and SATA/150 INTERFACES
The SHB Express specification defines optional I/O routings
from the SHB to the backplane. Chassis Plans' BPX3/14 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. Likewise, two SATA/150 connectors
are available on the backplane. The backplane also provides
a factory-build option that adds two additional, mirrored
SATA ports designed for use in RAID applications. Contact
Chassis Plans if you are interested in this BPX3/14 build
option.

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 CONNECTOR
Optional extended-current connector provides additional
power capacity for power-intensive applications -- up
to 100 Amps of +12V, 200 Amps of +3.3V and 100 Amps
of +5V.
ETHERNET INTERFACES - 10/100/1000BASE-T
Chassis Plans' BPX3/14 backplane supports the optional Ethernet
routing feature of the SHB Express 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.
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, +5V AUX,+12V, -12V and +3.3V power connections.
