RoHS Compliance
The VL-EPHs-P1 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.

HANDLING CARE
Warning! Care must be taken when handling the board not to touch the exposed circuitry
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.
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.
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.
EARTH GROUND REQUIREMENT
Warning! All mounting standoffs should be connected to earth ground (chassis ground). This
provides proper grounding for ESD and EMI purposes.

HARDWARE ASSEMBLY
The VL-EPHs-P1 uses a SUMIT-A bottom connector that attaches to the top of the stack. The
board is secured using two hardware standoffs on the corner mounting holes. These standoffs are
attached to the CPU board using pan head screws. Standoffs and screws are available as part
number VL-HDW-105 (metric thread) or VL-HDW-106 (English thread). The figure below
shows a typical installation.

The PCI Express Mini Card connector at J2 accepts a full-height PCI Express Mini Card. The
interface includes one PCIe x1 lane, one USB 2.0 channel, and the SMBus interface. The socket
is compatible with 802.11a/b/g Wi-Fi network adapters that operate in both the 2.4 and 5.0 GHz
spectra, GPS radio cards that enable time/date stamps and global location applications, 3G
modems, solid-state drives (SSDs), and USB (2.0) cards.
An optional PCI Express WiFi Mini Card is available for the VL-EPHs-P1 as VersaLogic part
number VL-WD10-CBN. A WiFi antenna (VL-CBR-ANT01) and a 12" WiFi card to bulkhead
RP-SMA transition cable (VL-CBR-0201) are also available. For more information, contact
Sales@VersaLogic.com.
To secure a Mini Card to the VL-EPHs-P1 use two screws (M2 x 5mm, Philips, pan head, 4mm,
stainless) and two washers (M2, split lock, OD 4.4mm, stainless). Screw and washer sets are
available in 10-count packages as part number VL-HDW-107.

The LED status indicator signals are provided to enable wireless communications add-in cards to
provide status indications via the built-in LEDs at positions D1 and D2 on the VL-EPMs-E1. The
behavior of the LEDs is determined by the add-in card manufacturer. The table below shows the
routing of the D1 and D2 LEDs to the Mini Card LED status signals.
