Thermal Considerations

CPU DIE TEMPERATURE

The CPU die temperature is affected by numerous conditions, such as CPU utilization, CPU
speed, ambient air temperature, air flow, thermal effects of adjacent circuit boards, external heat
sources, and many others.

The CPU is protected from over-temperature conditions by several mechanisms.
The CPU will automatically slow down by 50% whenever its die temperature exceeds +105°C.

When the temperature falls back below +105°C, the CPU resumes full-speed operation.
As a failsafe, if the CPU die temperature climbs above +115°C, the CPU will turn itself off to

prevent damage to the chip. Note that Intel does not warrant their CPUs in the event of this
occurrence.

M

ODEL DIFFERENCES

VersaLogic offers both commercial and industrial temperature models of the VL-EBX-37. The
basic operating temperature specification for both models is shown below.

Introduction

 VL-EBX-37S, A: 0°C to +60°C free air, no airflow
 VL- EBX-37E, F: -40°C to +85°C free air

To reliably function at extreme temperatures the extended temperature model specifications
deviate from the standard model in the following ways:

 The DRAM interface is slowed. PC3-6400 memory runs at 600 MHz. PC3-8500 memory

runs at 800 MHz.

 The DRAM refresh rates are doubled.
 The Front Side Bus speed is reduced to 800 MHz.
 Maximum processor speed is limited to 1200 MHz.
 The graphics core is limited to 400 MHz.

RoHS-Compliance

The VL-EBX-37 is RoHS compliant.

ABOUT ROHS

In 2003, the European Union issued Directive 2002/95/EC regarding the Restriction of the use of
certain Hazardous Substances (RoHS) in electrical and electronic equipment.

The RoHS directive requires producers of electrical and electronic equipment to reduce to
acceptable levels the presence of six environmentally sensitive substances: lead, mercury,
cadmium, hexavalent chromium, and the presence of polybrominated biphenyls (PBB) and
polybrominated diphenyl ethers (PBDE) flame retardants, in certain electrical and electronic
products sold in the European Union (EU) beginning July 1, 2006.

VersaLogic Corp. is committed to supporting customers with high-quality products and services
meeting the European Union’s RoHS directive.

components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board and
do not slide the board over any surface.

available.

The board should also be protected inside a closed metallic anti-static envelope

during shipment or storage.

cause excessive battery drain if the bag comes in contact with the bottom-side of
the VL-EBX-37.

ITHIUM BATTERY

L

Warning! To prevent shorting, premature failure or damage to the lithium battery, do not

place the board on a conductive surface such as metal, black conductive foam or
the outside surface of a metalized ESD protective pouch. The lithium battery may
explode if mistreated. Do not recharge, disassemble or dispose of in fire. Dispose
of used batteries promptly and in an environmentally suitable manner.

ANDLING CARE

H

Warning! Care must be taken when handling the board not to touch the exposed circuitry

with your fingers. Though it will not damage the circuitry, it is possible that small
amounts of oil or perspiration on the skin could have enough conductivity to cause
the contents of CMOS RAM to become corrupted through careless handling,
resulting in CMOS resetting to factory defaults.

ARTH GROUND REQUIREMENT

E

Warning! All mounting standoffs (eight on EBX and EPIC boards, four on PC/104 boards)

should be connected to earth ground (chassis ground). This provides proper
grounding for ESD and EMI purposes.

1. Install Memory

 Insert DDR3 DRAM module(s) into SO-DIMM sockets J13 and J29 and latch them into

place. If you install only one module, you must install it in the top socket, J13. If you use
DDR3 DRAM combined with a solid state drive (SSDDR3), you must install it in socket
J13.

2. Attach Cables and Peripherals

 Plug the LVDS adapter cable VL-CBR-201x into socket J31 on the bottom of the board.

Attach the adapter cable to the LVDS display. (On models A and F, socket J33 can
alternately be used.)

 Plug the USB CD-ROM drive, keyboard, and mouse into on-board USB ports (J2, J3, J4,

J8, J9, or J10).

 Plug the SATA data cable VL-CBR-0701 into socket J1 or J7, and attach the SATA hard

drive to the cable.

 Attach the ATX SATA power cable (VL-CBR-0401) to the ATX power supply and to

the SATA hard drive.

4. Review Configuration

 Before you power up the system, double check all the connections. Make sure all cables

are oriented correctly and that adequate power will be supplied to the VL-EBX-37 and
peripheral devices.

5. Power On

 Turn on the ATX power supply and the flat panel display. If the system is correctly

configured, a video signal should be present.

6. Select a Boot Drive

HARDWARE ASSEMBLY

The VL-EBX-37 mounts on four hardware standoffs using the corner mounting holes (A). These
standoffs are secured to the underside of the circuit board using pan head screws.

Four additional standoffs (B) must be used under the circuit board to prevent excessive flexing
when expansion modules are mated and separated. These are secured with four male-female
standoffs (C), threaded from the top side, which also serve as mounting struts for the PC/104
stack.

The entire assembly can sit on a table top or be secured to a base plate. When bolting the unit
down, make sure to secure all eight standoffs (A and B) to the mounting surface to prevent
circuit board flexing.

An extractor tool is available (part number VL-HDW-203) to separate the PC/104 modules from
the stack.

Note Standoffs and screws are available as part number VL-HDW-105 (metric thread)

or VL-HDW-106 (English thread).

Note All eight mounting standoffs should be connected to earth ground (chassis

ground). This provides proper grounding for ESD and EMI purposes.
