Introduction
5Lion (VL-EPMe-42) Reference Manual
Cautions
Electrostatic Discharge
CAUTION:
Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other
components. Handle circuit board at an ESD workstation. If an approved station is not
available, wearing a grounded antistatic wrist strap provides some measure of
protection. 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.
Ship and store the board inside a closed metallic antistatic envelope for protection.
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 Lion.
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 (four on PC/104 boards, eight on EBX and EPIC boards) should
be connected to earth ground (chassis ground). This provides proper grounding for EMI
purposes.

Lion (VL-EPMe-42) Reference Manual 6
Configuration and Setup
Initial Configuration
Use the following components for a typical development system:
Lion (VL-EPMe-42) computer
VL-ATX power supply
Display with DisplayPort input
Standard I/O paddleboard (VL-CBR-4005)
USB keyboard and mouse
USB CD-ROM drive (optional)
USB SSD or floppy disk drive (optional)
VL-HD35-xxx SATA hard drive (optional)
Use the following VersaLogic cables:
VL-EPH-V6 Mini DisplayPort converter (optional for LVDS)
VL-CBR-2032 Mini DisplayPort to VGA adapter (optional)
VL-CBR-0702 – SATA data cable
VL-CBR-1205 – Main power cable
Install Heat Sink VL-HDW-406 and Fan Assembly VL-HDW-413.
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 Lion
should be handled at an ESD workstation or while wearing a grounded antistatic wrist strap.
Before you begin, unpack the Lion 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]om immediately if any items are damaged or missing.
Gather all the peripheral devices you plan to attach to the Lion and their interface and power
cables.
Attach standoffs to the board to stabilize the board and make it easier to work with.
1. Install Memory (This product includes 0 memory SKUs. This step assumes a no memory
product is being configured)
Insert the supported DDR3L DRAM module into SO-DIMM socket J2 on the bottom of the
board and latch it into place.
2. Attach Cables and Peripherals
Attach a DisplayPort enabled display to one of the Mini DisplayPort connectors at J6 or
J21. (The VL-CBR-2032 mini DisplayPort to VGA adapter can be used as an alternate
option for VGA displays.)
Plug the VL-CBR-4005 paddleboard into Main User I/O connector.
2

Configuration and Setup
7Lion (VL-EPMe-42) Reference Manual
Plug a USB CD-ROM drive, USB keyboard, and USB mouse into any of the USB
connectors at J3 and J4 of the paddleboard.
Plug the SATA data cable VL-CBR-0702 into one of the SATA connectors. Attach a hard
drive to the connector on the cable.
Optionally, attach a LAN cable to one of the Ethernet connectors on the Lion using the
VL-CBR-1604 dual RJ-45 adapter cable.
3. Install Thermal Solution
See Installing the VersaLogic Thermal Solutions later in this manual
4. Attach Power
Plug the power adapter cable VL-CBR-1205 into socket J19. Attach the motherboard
connector of the ATX power supply to the adapter.
5. Review Configuration
Before you power up the system, double-check all the connections. Make sure all cables
are oriented correctly and that there is adequate power to the VL-EPMe-42 and peripheral
devices.
6. Power On
Turn on the ATX power supply and the video monitor. The presence of a video signal
indicates proper configuration of the system.
7. 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.
8. 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 Lion Support Page) for information on
accessing and configuring settings in the BIOS Setup utility. The BIOS Reference Manual
contains descriptions of all BIOS menus, submenus, and configuration options.
Operating System Installation
The standard PC architecture used on the VL-EPMe-42 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 Lion Product Support Page.

Hardware Assembly
The Lion provides both PCI and PCIe/104 OneBank connectors for adding expansion modules to
the bottom of the stack.
The entire assembly can fit on a tabletop or 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 secure 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.
