The XPT is End Of Life. Last time buy orders are being accepted until August 31, 2008.
Capability, flexibility and reliability are designed into Chassis Plans' XPT single board computer. The XPT is packed with key performance features such as dual Xeon processors, PCI-X bus communication, dual Gigabit Ethernet ports, the Intel® E7501 chipset and the M6-16H video controller from ATI Technologies®. These features are capable of handling the most challenging embedded computing applications. Dual Ultra320 SCSI interfaces exemplify the flexibility designed into the XPT. The SBC may be ordered with or without the SCSI interfaces, allowing you to closely match XPT functionality to specific system application needs. The XPT is the most powerful single board computer available!
The dual Xeon processors are ultra high performance devices that generate a lot of heat. The XPT provides a unique cooling system to assure proper heat dissipation out of the chassis. A high reliability 60x38mm 50CFM fan blows cooling air through a sculptured chamber through the processor heat sinks and out the rear panel. This vents processor heat directly out of the chassis instead of circulating it within the chassis. To limit noise, the fan speed is temperature controlled, speeding up with processor activity and increased heat. The XPT is the only SBC on the market with this cooling sophistication. Read our White Paper on the XPT Cooling System for details.

Dual Intel® Xeon processors 2.4GHz and 2.8GHz*
Intel's Hyper-Threading technology makes a single Xeon processor appear as two logical processors. The XPT's two physical Xeon processors will function as four logical processors in applications optimized for Hyper-Threading.
Intel's E7501 chipset provides support for dual Xeon processors, a 533 system bus, and PC1600 or PC2100 DDR memory with ECC.
The Intel E7501 chipset supports a system bus speed of 533MHz.
AMIBIOS8® has built-in advanced CMOS setup for system parameters, peripheral management for configuring on-board peripherals, PCI-to-PCI bridge support and PCI interrupt steering. Supports flash devices for BIOS upgrading via floppy interface. Also provides integrated support for USB mass storage devices such as USB, CD-ROM, CD-RW, etc. Custom BIOSs are available upon request.
Each Xeon processor supports a 512K integrated on-die Advanced Transfer Cache (L2). The cache is an 8-way set associative cache running at full processor core frequency. The Execution Trace Cache (L1) is a 12K data cache that stores thousands of decoded micro-operations. The purpose of this L1 cache is to remove decoder latency from the processor's main execution path, resulting in increased processor performance.
The DDR memory interface on the XPT consists of two channels, each terminating at a pair of DIMM module sockets. The XPT supports auto detection of up to 8GB of memory. The system BIOS automatically detects memory type, size and speed. The four memory sockets on the SBC must be populated in pairs, beginning with the sockets in Bank 1, and must contain ECC registered PC1600 or PC2100 DIMMS. All DIMMS must be the same speed (PC1600 or PC2100). The modules within a pair must be the same size; however, if two pairs are used, each pair can contain a different size module. The maximum memory capacity of the XPT is 8GB and the minimum interface bandwidth is 1600MB/s.
ERROR CHECKING AND CORRECTION
The memory interface supports ECC modes via BIOS setting for multiple-bit error detection and correction of all errors confined to a single nibble.
PCI-X BUS INTERFACE
The PCI-X bus interface supports a 64-bit PCI-X backplane interface running at either a 66MHz, 100MHz or 133MHz bus speed.
PCI BUS INTERFACE
The PCI bus interface supports either a 32-bit/33MHz or a 64-bit/66MHz PCI backplane interface.
The XPT provides a 16-bit ISA bus interface to the backplane for legacy ISA slots.
SYSTEM HARDWARE MONITOR
The Winbond W83783S chip supports hardware monitoring. The functions monitored are voltage, fan speed and temperature. The XPT hardware monitor software allows the user to program the monitor limits to provide trigger points for the application software. This allows the application program to monitor these trigger points in order to send system alert messages or perform corrective actions.
FLOPPY DRIVE INTERFACE
Supports up to two floppy disk drives in combinations of 360K to 2.88MB.
ULTRA XGA VIDEO INTERFACE
The ATI M6-16H video controller enables 2D/3D video acceleration and provides 16MB of integrated video DDR memory. The video controller supports pixel resolutions up to 1600 x 1200. Software drivers are available for most popular operating systems.
The Super I/O controller supports two full-function serial ports with independently programmable baud rates. The controller has two high-speed, NS16C550 compatible, UARTs with Send/Receive 16-Byte FIFOs. The IRQ for each serial port has BIOS selectable addressing.
ENHANCED BI-DIRECTIONAL PARALLEL INTERFACE
The parallel port interface is compatible with IBM PC/XT®, PC/AT®, PS/2T, Enhanced Parallel Port (EPP1.7, EPP1.9) and Extended Capabilities Port (ECP) modes of operation. Both the EPP and ECP modes are IEEE 1284 compliant. The parallel port has BIOS selectable addressing.
DUAL ETHERNET INTERFACES
The XPT has an internal PCI-X bus that connects to Intel's 82546GB Ethernet Controller chip. This board design feature provides high-speed dual Gigabit Ethernet on LAN ports 1 and 2. The XPT also supports existing 10Mb or 100Mb per second Ethernet networks over the same internal PCI-X bus. RJ-45 connectors located on the I/O bracket provide the mechanical interface to the Ethernet networks.
DUAL ULTRA320 SCSI INTERFACES
The Ultra320 SCSI interfaces use a dual-channel Adaptec AIC-7902BR SCSI controller chip. The SCSI interfaces use the SBC's internal PCI-X bus to maximize device data transfer speeds. The maximum data transfer speed is 320MB/s, and up to 15 SCSI devices per interface are supported. The interfaces comply with the SPI-3 standard and are compatible with both single-ended and Low Voltage Differential (LVD) SCSI I/O. Software drivers are available for most popular operating systems. The SBC is available without the SCSI interfaces.
EIDE ULTRA ATA/100 INTERFACES (DUAL)
Dual high-performance PCI Bus Master EIDE interfaces are capable of supporting up to two IDE disk drives each in a master/slave configuration. The interface supports Ultra ATA/100 with synchronous ATA mode transfers up to 100MB per second.
The programmable watchdog timer provides a system reset with a total range of 30ms to 60 seconds. The programmable increments of the watchdog are 30ms, 10s and 60s.
KEYBOARD AND PS/2 MOUSE INTERFACES
The mini DIN connector located on the I/O bracket provides an external interface for a PS/2 mouse and keyboard. A "Y" adapter plugged into the mini DIN connector allows the PS/2 mouse and keyboard to share the same port. Internal PS/2 mouse and keyboard headers are also available. A self-resetting fuse protects the +5V line of the keyboard and the mouse.
-12V @ <100mA*
* From Backplane via PICMG® Connector.
** From ATX12V power supply or equivalent via P24 connector.
The Xeon processor's power requirements created the need for an additional on-board 4-pin power connector (P24). This connector requires +12V from an external power supply that conforms to the ATX12V power specification.
This external power supply should have a minimum wattage rating of at least 250W. The XPT also requires that 3.3V be applied to the backplane from the power supply.
POWER FAIL DETECTION
The XPT continuously monitors the incoming +5V and +3.3V power lines from the system backplane. If the +5V line drops below 4.75 volts or the +3.3V line drops below 2.97 volts, the XPT issues a hardware-reset command. This feature helps maintain control and allows the system to automatically restart. A two-pin header is available for applications that require an external reset switch. On-board power lines are also monitored in a similar fashion.
Built-in lithium battery for data retention of CMOS memory.
In a typical PCI/ISA backplane, the XPT's air duct design enables placement of half-size PCI cards approximately 2.3" (58.4mm) or three slots away from the SBC. Full-length cards can be placed four slots away in the backplane or approximately 3.2" (81.3mm) from the XPT.
