Dual Intel® Xeon™ processors 2.4GHz and 2.8GHz
Intel's Hyper-Threading technology makes a single Intel® Xeon™ processor appear as two logical processors. The operating system and application must be optimized for Hyper-Threading. The XPT's two physical Intel® Xeon™ processors will function as four logical processors in applications optimized for Hyper-Threading.
The Intel® E7501 chipset provides support for dual Intel® 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 Intel® 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.
The memory interface supports ECC modes via BIOS setting for multiple-bit error detection and correction of all errors confined to a single nibble.
The PCI-X bus interface supports a 64-bit PCI-X backplane interface running at either a 66MHz, 100MHz or 133MHz bus speed.
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.
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.
Supports up to two floppy disk drives in combinations of 360K to 2.88MB.
The ATI M6-C16H 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.
The parallel port interface is compatible with IBM PC/XT, PC/AT, PS/2, 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.
The XPT supports two USB 1.1 ports for serial transfers at 12 or 1.5Mbit/sec. The Universal Serial Bus (USB) is an interface allowing for connectivity to many standard PC peripherals via an external port.

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.
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.
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.
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.

The Intel® Xeon™ processor 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.
The XPT single board computer supports processors speeds of 3.06GHz and beyond. These faster Intel® Xeon™ processors require more power and replaces the 4-pin power connector (P24) with an 8-pin on-board power connector to accommodate this additional power demand.
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.
The system power supply must conform to the power sequencing specifications of ATX compliant power supplies. Voltage levels must be regulated within a range of +/- 5%.
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.

An Intel® Xeon™ processor can consume as much as 70 Watts of power on the XPT. The XPT's cooling solution consists of an air duct assembly attached to the SBC, a high-reliability cooling fan mounted to the air duct intake, and passive heat sinks mounted to each processor. The fan maintains air movement over the processors' passive heat sinks and the air duct assembly directs the airflow over critical components. Warm air is exhausted from vents located on the SBC's I/O bracket.
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.
