KNOWN ISSUES

Hardware

 The PCIe Minicard and the two PCIe Express ports on the PCIe/104

connected to an on-board PCIe Gen2 Switch (a PLX PEX 8605). Certain older, non-compliant
Gen 1 devices will not link up properly with this switch (such as the Startech MPEXSATA221
PCIe-to-SATA bridge using a Silicon Image Sil3132 bridge).

†

OneBank† connector are

 Holding the reset button in when powering on the board prevents booting and requires a re-power.

Make sure the reset button is not being asserted low when powering on the board.

 If the +5 V input voltage is low (below +5 V) and the wires to the power supply are long (greater

than 12 inches) or too low of a gauge (less than 16 AWG) the board may take longer to power on
due to in-rush current causing a droop on the + 5 V power at the power connector input. This
droop in the +5 V power causes the board to switch the regulators off and then back on again.
Typically, this results in only a short delay (less than 1 second). Users should measure the +5 V
power at the connector with their particular power delivery system to see if the voltage at that point
ever drops below about +4.75 V when power is applied.

BIOS

 S3 wake using power button may require keyboard/mouse activity to turn on the display.
 The first display port (J3) can also support HDMI (it is a DP++ port). To support HDMI there are

two options:

 Use an active DP-to-HDMI adapter
 Use a passive DP-to-HDMI adapter and request a custom BIOS from VersaLogic.

 Legacy USB support is not available in xHCI (USB 3.0) mode. Non-UEFI pre-OS and installation

environments may require EHCI (USB 2.0) mode for USB keyboard functionality.

Operating Systems

 Driver support (via VersaAPI) for SPX-5 module and I

Thermal Considerations

The operating temperature for the Bengal is -40 °C to +85 °C, de-rated -1.1 °C per 305m (1,000
ft.) above 2,300m (7,500 ft.). All Bengal models include a rigid-mount heat plate thermal solution.
Refer to Chapter 6 for information on additional thermal solutions.

Cautions

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

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.



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 Bengal.

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

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

If you are using a CBR-5015 paddleboard with the Bengal board, do not connect an

5015 paddleboard as well.

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

Initial Configuration

The following components are recommended for a typical development system:

 Bengal (VL-EPMe-30) computer
 VL-ATX power supply
 VL-MM9-xxEBN DDR3 SO-DIMM module (see System RAM)
 VGA display (or display with DisplayPort input)
 Standard I/O paddleboard (VL-CBR-5015)
 USB keyboard and mouse
 USB CD-ROM drive (optional)
 USB SSD or floppy disk drive (optional)
 VL-HD35-xxx SATA hard drive (optional)

The following VersaLogic cables are recommended:

Configuration and Setup

 VL-CBR-1204 VGA adapter cable (or VL-EPH-V6 Mini DisplayPort converter)
 VL-CBR-0702 or VL-CBR-0701 – SATA data cable
 VL-CBR-0401 – ATX to SATA power adapter
 VL-CBR-0804 – Ethernet RJ-45 adapter cable
 VL-CBR-1008 – Main power cable

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 Bengal
should be handled at an ESD workstation or while wearing a grounded antistatic wrist strap.

Before you begin, unpack the Bengal 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
[e-mail] immediately if any items are damaged or missing.

Gather all the peripheral devices you plan to attach to the Bengal and their interface and power
cables.

It is recommended that you attach standoffs to the board (see Hardware Assembly) to stabilize
the board and make it easier to work with.

1. Install Memory

 Insert the DDR3L DRAM module into the SO-DIMM socket J9 on the bottom side of the

board and latch it into place.

Bengal (VL-EPMe-30) Reference Manual 6

2. Attach Cables and Peripherals

 Plug the VGA cable VL-CBR-1204 into socket J5. Attach the cable to the VGA display.

(Alternatively, you can attach a DisplayPort enabled display to one of the Mini DisplayPort
connectors at J3 or J22. The VL-EPH-V6 video adapter card converts DisplayPort output
to LVDS.)

 Plug the VL-CBR-5015 paddleboard into socket J18.

Configuration and Setup



 Plug a USB CD-ROM drive, USB keyboard, and USB mouse into any of the USB

connectors at J4 and J5 of the paddleboard.

 Plug the SATA data cable VL-CBR-0702 into socket J2. Attach a hard drive to the

connector on the cable.

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

drive.

 Optionally, attach a LAN cable to either of the Ethernet connectors at J1 or J7 on the

Bengal using the VL-CBR-0804 RJ-45 adapter.

3. Attach Power

 Plug the power adapter cable VL-CBR-1008 into socket J20. Attach the motherboard

connector of the ATX power supply to the adapter.

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-EPMe-30 and
peripheral devices.

5. Power On

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

configured, a video signal should be present.

6. Select a Boot Drive

 During startup, press <CTRL> <B> to display the boot menu. Insert the OS installation

CD in the CD-ROM drive and select to boot from the CD-ROM drive.

7. Install Operating System

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

system manufacturer. (See Operating System Installation.)

BIOS Setup Utility

Refer to the BIOS Reference Manual (available on the Bengal Product Support Page) for
information on accessing and configuring settings in the BIOS Setup utility. All BIOS menus,
submenus, and configuration options are described in the BIOS Reference Manual.

Operating System Installation

The standard PC architecture used on the VL-EPMe-30 makes the installation and use of most of
the standard x86-based operating systems very simple. The operating systems listed on the

VersaLogic OS Compatibility Chart use the standard installation procedures provided by the

maker of the OS. Special optimized hardware drivers for a particular OS, or a link to the drivers,
are available at the Bengal Product Support Page.

Integrator’s Note:

Booting to Windows requires changing the default boot OS in the BIOS Setup utility.

Hardware Assembly

The Bengal provides both PCI and PCIe/104 OneBank connectors for adding expansion modules
to the bottom of the stack.

The entire assembly can sit on a tabletop or it can be secured to a base plate. When bolting the
unit down, make sure to secure all four standoffs to the mounting surface to prevent circuit board
flexing. Standoffs are secured to the top circuit board using four pan head screws. Standoffs and
screws are available as part number VL-HDW-105.

An extractor tool is available (part number VL-HDW-203) to separate the expansion modules from
the stack. Use caution when using the extractor tool not to damage any board components.
