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 Condor.
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.

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 drive that is not already attached to the power supply
(hard drive or CD-ROM drive).
3. Install Thermal Solution
See the Installing Thermal Solutions section
3. Review Configuration
Before you power up the system, double-check all the connections. Make sure all cables are
oriented correctly, that adequate power is supplied to the Condor 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 Utility
Refer to the VersaLogic System Utility Reference Manual for information on how to configure
the Condor BIOS.
The Condor permits you to store user-defined BIOS settings. This enables you to retrieve those
settings from cleared or corrupted CMOS RAM, or battery failure. All BIOS defaults can be
changed, except the time and date. BIOS defaults can be updated with the BIOS Update Utility.
CAUTION: If BIOS default settings make the system unbootable and prevent the user
from entering the BIOS Setup utility, the Condor must be serviced by the factory.
Default BIOS Setup Values
After CMOS RAM clears, the system loads default BIOS parameters the next time the board
powers on. 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 Condor makes the installation and use of most of the
standard x86-based operating systems very simple. The operating systems listed on the
VersaLogic Software Support page use the standard installation procedures provided by the
maker of the operating system. Special optimized hardware drivers for a particular operating
system, or a link to the drivers, are available on the Condor Support Page.

Board Features
CPU
The Intel Core 6xxx SoC features integrated 3D graphics, video encode and decode, and memory
and display controllers in one package. The following CPU configurations are available:
VL-EPU-4460-EAP: Intel Core 6100 – 2.3 GHz, Dual Core
VL-EPU-4460-EBP: Intel Core 6300 – 2.4 GHz, Dual Core
VL-EPU-4460-EDP: Intel Core 6600 – 2.6 GHz, Dual 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 6xxx 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. (See the Intel Core Processor U/Y Series
Datasheet for complete information.)
System RAM
The Condor has socketed SDRAM with the following characteristics:

Real-Time Clock (RTC)
The Condor features a real-time clock/calendar (RTC) circuit. The Condor supplies RTC voltage
in S5, S3, and S0 states, but requires an external +2.75 V to +3.3 V battery connection. Refer to
the section titled Battery Power Options on page 21 for more information. The BIOS Setup
utility sets the RTC.

power supply.
If your application requires a custom cable, the following information will be useful:
VL-EPU-4460 Board Connector Mating Connector
Molex 055959-0830 Molex 051353-0800
Power Requirements
The Condor requires a single +8 to +30 VDC supply capable of providing at least 35 W average
power that can also provide a peak power of 50 W. The input DC supply creates both the standby
and payload voltages provided to the CPU module.
The exact power requirements for the Condor depend on several factors, including CPU
configuration (the number of cores, CPU clock rate), memory configuration, peripheral
connections, and attached devices, and others. For example, driving long RS-232 lines at high
speed can increase power demand.
The VersaLogic VL-PS-ATX12-300A is a 1U size ATX power supply suitable for use with the
Condor. Use the VL-CBR-0809 adapter cable to attach the power supply to the main power
connector.
Power Delivery Considerations
Using the VersaLogic approved power supply (VL-PS-ATX12-300A) and power cable
(VL-CBR-0809) will ensure high quality power delivery to the board. Customers who design
their own power delivery methods should take into consideration the guidelines below to ensure
good power connections.
The specifications for typical operating current do not include any off-board power usage that
fed through the Condor power connector. Expansion boards and USB devices plugged into the
board will source additional power through the Condor power connector.

Board Features
20 VL-EPU-4460 Reference Manual
Do not use wire smaller than 22 AWG. Use high quality UL 1007 compliant stranded wire.
The length of the wire should not exceed 18 inches.
Avoid using any additional connectors in the power delivery system.
The power and ground leads should be twisted together, or as close together as possible to
reduce lead inductance.
A separate conductor must be used for each of the power pins.
All power input pins and all ground pins must be independently connected between the
power source and the power connector.
Use a high quality power supply that can supply a stable voltage while reacting to widely
varying current draws.
Power Button
The User I/O connector (shown in Figure 15 on page 32) includes an input for a power button. A
momentary short to ground or assertion of pin 17 will cause a power button ACPI event. The
button event can be configured in Windows to enter an S3 power state (Sleep, Standby, or
Suspend-to-RAM), an S4 power state (Hibernate or Suspend-to-Disk), or an S5 power state
(Shutdown or Soft-Off). This connector uses IEC 61000-4-2-rated TVS components to help
protect against ESD damage.
A power button is provided on the VL-CBR-4005B paddleboard. Refer to the chapter titled VL-
CBR-4005B Paddleboard, beginning on page 48 for more information.
Supported Power States
This table lists the Condor’s supported power states.
Table 4. Supported Power States
Power state Description
S0 (G0) Working
S1 (G1-S1)
All processor caches are flushed and the CPUs stop executing instructions. Power to
the CPUs and RAM is maintained. Devices that do not indicate they must remain on
may be powered down.
S3 (G1-S3) Commonly referred to as Standby, Sleep, or Suspend-to-RAM. RAM remains powered.
S4 (G1-S4)
Hibernation or Suspend-to-Disk. All content of main memory is saved to non-volatile
memory, such as a hard drive, and is powered down.
S5 (G2)
Soft Off. Almost the same as G3 Mechanical Off, except that the power supply still
provides power, at a minimum, to the power button to allow return to S0.
A full reboot is
required. No previous content is retained. Other components may remain powered so
the computer can "wake" on input from the keyboard, clock, modem, LAN, or USB
device.
G3 Mechanical off (ATX supply switch turned off).
