HANDLING PRECAUTIONS
WARNING: This product has components which may be damaged by electrostatic discharge.
To protect your system host board (SHB) from electrostatic damage, be sure to observe the following
precautions when handling or storing the board:
 Keep the SHB in its static-shielded bag until you are ready to perform your installation.
 Handle the SHB by its edges.
 Do not touch the I/O connector pins.
 Do not apply pressure or attach labels to the SHB.
 Use a grounded wrist strap at your workstation or ground yourself frequently by touching the
metal chassis of the system before handling any components. The system must be plugged into an
outlet that is connected to an earth ground.
 Use antistatic padding on all work surfaces.
 Avoid static-inducing carpeted areas.
RECOMMENDED BOARD HANDLING PRECAUTIONS
This SHB has components on both sides of the PCB. Some of these components are extremely small and
subject to damage if the board is not handled properly. It is important for you to observe the following
precautions when handling or storing the board to prevent components from being damaged or broken off:
 Handle the board only by its edges.
 Store the board in padded shipping material or in an anti-static board rack.
 Do not place an unprotected board on a flat surface.

Before You Begin
INTRODUCTION
It is important to be aware of the system considerations listed below before installing your JXT6966 or
JXTS6966 (6966-xxx) SHB. Overall system performance may be affected by incorrect usage of these
features.
MOUSE/KEYBOARD “Y” CABLE
If you have an IOB33 I/O board in your system and you are using a “Y” cable attached to the bracket
mounted mouse/keyboard mini Din connector, be sure to use Trenton’s “Y” cable, part number 5886-000.
Using a non-Trenton cable may result in improper SHB operation.
DDR3-1333 MEMORY
Trenton recommends ECC registered DDR3 memory modules for use on the JXT6966/JXTS6966 SHBs
and these ECC registered (72-bit) DDR3 Mini-DIMMs must be PC3-10600 or PC3-8500 compliant.
Unbuffered ECC DDR3 Mini-DIMMs are also supported on the JXT boards, but you cannot mix the two
different memory types on the same SHB.
NOTES:
• To maximize system performance and reliability, Trenton recommends populating each
memory channel with DDR3 Mini-DIMMs with the same interface speed.
• All memory modules must have gold contacts.
• Low voltage (DDR3L) Mini-DIMMs are not supported.
• The SHB supports the following memory module memory latency timings:
o 6-6-6 for 800MHz DDR3 Mini-DIMMs
o 7-7-7 and 8-8-8 for 1066MHz DDR3 Mini-DIMMs
o 9-9-9 for 1333MHz DDR3 Mini-DIMMs
• Populating the memory sockets with Mini-DIMMs having different speeds is supported
on the SHB; however, the overall memory interface speed will run at the speed of the
slowest Mini-DIMM.
• Populate the memory sockets starting with the Mini-DIMM socket closest to the CPU
and work your way toward the edges of the SHB as illustrated in the chart below:
Population order CPU1 CPU2*
1 BK00 BK10
2 BK01 BK11
3 BK02 BK12
*CPU2 is available on the JXT6966 dual-processor board version only
*Using a balanced memory population approach ensures maximum memory interface
performance. A “balance approach” means using an equal number of Mini-DMMs
for each processor on a dual-processor JXT6966 SHB whenever possible.
The memory DIMMs on the SHB connect directly to the CPU and at least one memory module must be
installed on the board. The JXTS6966 SHB versions feature one processor; however, memory sockets
BK10, BK11 and BK12 are installed on the SHB but are not active in this single-processor board version.
SATA RAID OPERATION
The Intel®3420 Platform Controller Hub (PCH) used on the SHB features Intel® Rapid Storage
Technology (Intel®RST), which allows the PCH’s SATA controller to be configured as a RAID controller
supporting RAID 0, 1, 5 and 10 implementations. To configure the SATA ports as RAID drives or to use
advanced features of the PCH, you must install the Intel® RST driver software. A link to the software is
also located on Trenton’s website by accessing the Downloads tab of the JXT6966 product detail page or
the RAID Drivers section of the Technical Support page.

JXT6966 / JXTS6966 Technical Reference
POWER CONNECTION
The PICMG®1.3 specification supports soft power control signals via the Advanced Configuration and
Power Interface (ACPI). The JXT6966/JXTS6966 supports these signals, controlled by the ACPI and are
used to implement various sleep modes. When control signals are implemented, the type of ATX or EPS
power supply used and the operating system software will dictate how system power should connect to the
SHB. It is critical that the correct method be used. Refer to - Power Connection section in the JXT manual
to determine the method that will work with your specific system design. The Advanced Setup chapter in
the manual contains the ACPI BIOS settings.
PCI EXPRESS 2.0 LINKS AND PICMG® 1.3 BACKPLANES
The PCI Express® links on the JXT6966 connect directly to the processors. These links can operate as
either PCI Express 2.0 or PCI Express 1.1 links based on the end-point devices on the backplane that are
connected to the SHB. In addition to automatically configuring themselves for either PCIe 2.0 or PCIe 1.1
operations, the links also configure themselves for either graphics or server-class operations. In other
words, the multiple x4 links from the processors (links A0, A1, A2 and A3) can be combined into a single
x16 PCIe electrical link or multiple x8 links on a backplane. The CPU’s x4 links can train down to x1
links, but cannot bifurcate into multiple x1 links. The PCIe link (B0) from the board’s PCH has a x4
default configuration and can be made to bifurcate into four, x1 PCIe links with a factory modification to
the JXT board. Contact Trenton if you require this B0 link configuration change. An optional PEX10
module connected to a dual-processor JXT6966 provides more backplane links than are currently supported
in the PICMG 1.3 specification. This JXT6966 capability provides additional PCI Express bandwidth and
option card support in the system design. Refer to the PCI Express®Reference chapter and to Appendix C
- PCI Express Backplane Usage of this manual for more information.
PICMG 1.3 BACKPLANE I/O
The JXT6966 and JXTS6966 enable the following PICMG 1.3 backplane I/O connectivity via the SBC’s
edge connector C:
• Four USB 2.0 interfaces
• One 10/100Base-T Ethernet interface
PICMG 1.3 BACKPLANE CLASSIFICATION
The JXT6966 and JXTS6966 are system host boards that can operate as either a Server or Graphics-Class
PICMG 1.3 SHB. The JXT SHBs are essentially combo-class boards because of the capabilities of the PCI
Express links built into the SHB’s processors. Trenton recommends using a combo-class PICMG 1.3
backplane such as the Trenton BPC7009 or BPC7041 with the SHBs in order to ensure the use of all
available backplane option card slots. See Appendix C, PCI Express Backplane Usage for more details.
OFF-BOARD VIDEO CARD USAGE
If the system design requires an off-board video card, then the card must be placed in a backplane slot
driven with PCI Express links from the JXT6966’s first processor. This is an Aptio® 4.x BIOS limitation
that may be corrected in future software revisions. Listed below are the acceptable BPC7009 and BPC7041
backplane slots for use with an off-board video card:
BPC7009 - Card slot PCIe1, PCIe2 or PCIe3
BPC7041 - Card slot PCIe6, PCIe7, PCIe8, PCIe9 or PCIe10
BIOS
The JXT6966 and JXTS6966 feature the Aptio® 4.x BIOS from American Megatrends, Inc. (AMI) with a
ROM-resident setup utility called the Aptio Text Setup Environment or TSE. Details of the Aptio TSE are
provided in the separate JXT6966 / JXTS6966 BIOS Technical Reference manual.
FOR MORE INFORMATION
For more information on any of these features, refer to the appropriate sections JXT6966 / JXTS6966
Hardware Technical Reference Manual. The BIOS and hardware technical reference manuals are available
under the Downloads tab on the JXT6966 or JXTS6966 web pages.
