Cautions

Electrostatic Discharge

CAUTION:

Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other

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.

After removing the board from its protective wrapper, place the board on a grounded,

static-free surface, component side up. Use an antistatic foam pad if available.

The board should also be protected inside a closed metallic antistatic envelope during

shipment or storage.



Note:

The exterior coating on some metallic antistatic bags is sufficiently conductive to cause excessive

battery drain if the bag comes in contact with the bottom side of the Harrier.

Handling Care

CAUTION:

Avoid touching the exposed circuitry with your fingers when handling the board. 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.

Earth Ground Requirement

CAUTION:

All mounting standoffs should be connected to earth ground (chassis ground). This

provides proper grounding for EMI purposes.

Configuration and Setup

Initial Configuration

The following components are recommended for a typical development system with the Harrier

EPU:

 VL-CBR-0809 power cable and a power supply

 VL-CBR-4005B paddleboard and VL-CBR-4005A cable. Refer to the chapter titled “VL-

CBR-4005B Paddleboard” for details.

 USB keyboard and mouse

 SATA hard drive

 USB CD-ROM drive or other installation device and media

 DisplayPort or VGA monitor and a VL-CBR-2032 Mini DisplayPort-to-VGA adapter

 A thermal solution (using either VersaLogic accessories or a customer-designed solution)

You will also need an operating system (OS) installation CD-ROM.

Basic Setup

The following steps outline the procedure for setting up a typical development system. The

Harrier should be handled at an ESD workstation or while wearing a grounded antistatic wrist

strap.

Before you begin, unpack the Harrier and accessories. Verify that you received all the items you

ordered. Inspect the system visually for any damage that may have occurred in shipping. Contact

[email protected] immediately if any items are damaged or missing.

Gather all the peripheral devices you plan to attach to the Harrier as well as their interface and

power cables. It is recommended that you attach standoffs to the board to stabilize the board and

make it easier to work with.

The next figure shows a typical setup for the Harrier in the development environment.

Configuration and Setup

14 VL-EPU-4011 Reference Manual

Figure 3. Typical Development Configuration

1. Attach Cables and Peripherals

 Attach a monitor to the baseboard’s Mini DisplayPort++ connector using a VL-CBR-2032, or

cable directly to a DisplayPort monitor

o Note: Some operating systems will detect both the Mini DisplayPort and LVDS

connections as active even when not using LVDS. Operating System would then set

an extended display which makes some login screen not viewable. Turn off LVDS in

the BIOS menu should this occur. BIOS screens are mirrored, not extended.

 Attach a SATA hard disk to the baseboard’s SATA connector using a VL-CBR-0701 or VL-

CBR-0702 cable.

 Attach a VL-CBR-4005B paddleboard to the baseboard’s User I/O connector.

Configuration and Setup

VL-EPU-4011 Reference Manual 15

 Connect a USB keyboard and USB mouse to the USB Type-A connectors on the VL-CBR-

4005B paddleboard.

 Attach a USB DVD-ROM or other installation media to the USB 3.0 connector on the EPU-

4011.

2. Connect Power Source

 Plug the power adapter cable VL-CBR-0809 into the main power connector on the baseboard.

Attach the motherboard connector of the ATX power supply to the adapter.

 Attach an ATX power cable to any 3.5-inch drive that is not already attached to the power

supply (hard drive or DVD-ROM drive).

3. Review Configuration

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

oriented correctly, that adequate power will be supplied to the Harrier, and all attached

peripheral devices.

4. Power On

 Turn on the ATX power supply and the video monitor. If the system is correctly configured, a

video signal should be present.

5. Install Operating System

 Install the operating system according to the instructions provided by the operating system

manufacturer.

BIOS Setup

The Harrier permits the storage of user-defined BIOS settings. This enables you to retrieve

settings from cleared or corrupted CMOS RAM, or battery failure. All BIOS defaults can be

changed except the time and date. BIOS defaults are updated using the BIOS Update Utility.

CAUTION: If BIOS default settings make the system unbootable and prevent the user from

entering the BIOS Setup utility, the Harrier must be serviced by the factory.

Default BIOS Setup Values

After CMOS RAM clears, the system loads default BIOS parameters the next boot. The default

CMOS RAM setup values are used in order to boot the system whenever the main CMOS RAM

values are blank, or when the system battery is dead or has been removed from the board.

Operating System Installation

The standard PC architecture used on the Harrier makes the installation and use of most of the

standard x86-based operating systems very simple. Special optimized hardware drivers for a

particular operating system, or a link to the drivers, are available on the Harrier Product Page.

Board Features

CPU

The Intel Atom E39xx SoC features integrated 3D graphics, video encode and decode, and

memory and display controllers. The following CPU configurations are available:

 VL-EPU-4011-EAP: Intel Atom 3930 – 1.3 GHz, Dual Core

 VL-EPU-4011-EDP: Intel Atom 3950 – 1.6 GHz, Quad Core

CPU Die Temperature

The CPU die temperature is affected by numerous conditions, such as CPU utilization, CPU

speed, ambient air temperature, airflow, thermal effects of adjacent circuit boards, external heat

sources, and many others.

The thermal management for the Intel Atom E39xx series of processors consists of a sensor

located in the core processor area. The processor contains multiple techniques to help better

manage thermal attributes of the processor. It implements thermal-based clock throttling and

thermal-based speed step transitions. There is one thermal sensor on the processor that triggers

Intel's thermal monitor (the temperature at which the thermal sensor triggers the thermal monitor

is set during the fabrication of the processor). Triggering of this sensor is visible to software by

means of the thermal interrupt LVT entry in the local APIC.

System RAM

The Harrier has soldered-on DDR3L ECC with the following characteristics:
