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.

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

defaults.

All mounting standoffs should be connected to earth ground (chassis ground). This
provides proper grounding for EMI purposes.

Electrostatic Discharge

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:

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

CAUTION:

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

13 VL-EPU-4460 Reference Manual

Configuration and Setup

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.

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.

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

maker of the operating system. Special optimized hardware drivers for a particular operating
system, or a link to the drivers, are available on the

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.

Board Features

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 thermal­based 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

Datasheet for complete information.)

System RAM

The Condor has socketed SDRAM with the following characteristics:

VL-EPU-4460-EBP DDR4 16 GB 2133 MT/s – Dual Channel
VL-EPU-4460-ECP DDR4 16 GB 2133 MT/s – Dual Channel

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.

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

 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 VL­CBR-4005B Paddleboard, beginning on page 48 for more information.

1. This pin is not grounded on the Condor on socket 1, since it can be used to detect the presence of
an mSATA module versus a Mini PCIe card.

2. This pin is not grounded on the Condor to make it available for mSATA module detection.

3. This signal drives the blue LED activity indicator shown in Figure 14. This LED lights with mSATA
disk activity (if supported by the mSATA module).

4. Some Mini PCIe cards use this signal as a second Mini PCIe card wireless disable input. On the
Condor, this signal is available for use for mSATA versus Mini PCIe card detection. There is an
option on the VersaLogic Features BIOS Setup utility screen for setting the mSATA detection
method.

W_DISABLE# Signal

The W_DISABLE# signal is for use with optional wireless Ethernet Mini PCIe cards. The signal
enables you to disable a wireless card’s radio operation in order to meet public safety regulations
or when otherwise desired. W_DISABLE# is an active low signal that when driven low (shorted
to ground) disables radio operation on the Mini PCIe card wireless device. When W_DISABLE#
is not asserted, or in a high impedance state, the radio may transmit if not disabled by other
means such as software. The W_DISABLE# signals for each of the two Minicards are controlled
by registers in the FPGA.

SPX* Expansion Bus

Up to two serial peripheral expansion (SPX) devices can be attached to the Condor at connector
using a CBR-0901 cable. The SPX interface provides the standard serial peripheral interface
(SPI) signals: CLK, MISO, and MOSI, as well as two chip selects, SS0# and SS1#. The +5 V
power provided to pin 1 of the SPX connector is protected by a 1 A resettable fuse.

The figure below shows the location and pin orientation of the SPX connector.

SPI is, in its simplest form, a three wire serial bus. One signal is a clock, driven only by the
permanent master device on-board. The others are Data In and Data Out with respect to the
master. The SPX implementation on the Condor supports chip selects. The master device
initiates all SPI transactions. A slave device responds when its chip select is asserted and it
receives clock pulses from the master. All four common SPI modes are supported through the use
of clock polarity and clock idle state controls.

The SPI clock is derived from a 24 MHz PCI clock and can be software-configured to operate at
the following frequencies:

 6 MHz (24 MHz/4)
 3 MHz (24MHz/8)
 1.5 MHz (24MHz/16)
 0.75 MHz (24MHz/32)

controllers provide a standard IEEE 802.3 Ethernet interface for 1000Base-T, 100Base-TX, and
10Base-T applications. The I210-IT Ethernet controller auto-negotiates connection speed.
Drivers are readily available to support a variety of operating systems. For more information on
this device, refer to the Intel I210 Ethernet Controller datasheet

Integrator’s Note: Ethernet Port 1 supports network boot; Port 0 does not.

Ethernet Connector

The Ethernet connector provides access to the Ethernet ports 0 and 1. The connector uses IEC
61000-4-2-rated TVS components to help protect against ESD damage. The figure below shows
the location and pin orientation of the Ethernet connector.

Thermal Considerations

By itself, the heat plate is not a complete thermal solution. Integrators should either implement a

85 ºC.

The heat plate is permanently affixed to the Condor and must not be removed. Removal of the
voids the product warranty and can damage the CPU.

10

Thermal Considerations

This chapter discusses the following topics related to thermal issues:

 Selecting the correct thermal solution for your application
 EPU-4460 thermal characterization
 Installing the passive (HDW-416 heat sink), the active (HDW-415 fan), thermal solutions

available from VersaLogic

Selecting the Correct Thermal Solution for Your Application

This section provides guidelines for the overall system thermal engineering effort.

Heat Plate

The heat plate supplied with the Condor is the basis of the thermal solution. The heat plate draws
heat away from the CPU chip as well as other critical components. Some components rely on the
ambient air temperature at or below the maximum specified 85 ºC temperature.

The design of the heat plate assumes that the user’s thermal solution will maintain the top surface
of the heat plate at 90 ºC or less. If that temperature threshold is maintained, the CPU will remain
safely within its operating temperature limits.

CAUTION:

thermal solution using the accessories available from VersaLogic or develop their own thermal
solution that attaches to the heat plate, suitable for environments in which the EPU-4460 will be
used. As stated above, the thermal solution must be capable of keeping the top surface of the
heat place at or below 90 ºC and the air surrounding the components in the assembly at or below

heat plate voids the product warranty. Attempting to operate the Condor without the heat plate

System-level Considerations

The Condor is often mounted directly to another thermally controlled surface via its heat plate
(that is, the inside surface of an enclosure). In this case, the user needs to maintain the heat plate
at or below 90 ºC by controlling the mounting surface temperature. The EPU-4460 thermal
solutions available from VersaLogic – the HDW-406 heat sink with or without the HDW-415
fan, or the HDW-408 heat pipe block – can be used in the user’s final system or only used during
product development as a temporary bench-top solution.

The ambient air surrounding the EPU-4460 needs to be maintained at 85 ºC or below. This may
prove to be challenging depending on how and where the EPU-4460 is mounted in the end user
system.

VL-EPU-4460 Reference Manual 53

Thermal Considerations

At this temperature, the CPU cores throttle back to a lower speed. This
speed.

At this temperature, the operating system typically puts the board into a
sleep or other low-power state.

The CPU turns itself off when this temperature is reached. This is a fixed
trip point and cannot be adjusted.

Notes:

2. The default value in the BIOS Setup utility for this trip point is 100 ºC.

The decision which thermal solution to use relies on several factors including:

 Number of CPU cores in the SoC (single, dual, or quad)
 CPU and video processing utilization by the user application
 Temperature range within which the EPU-4460 will be operated
 Air movement (or lack of air movement)

Most of these factors involve the demands of the user application on the EPU-4460 and cannot
be isolated from the overall thermal performance. Due to the interaction of the user application,
the Condor thermal solution, and the overall environment of the end system, thermal
performance cannot be rigidly defined.

The ambient air surrounding the EPU-4460 needs to be maintained at 85 ºC or below. This would
include the space between the two main boards as well as the space beneath an installed Mini
PCIe expansion board. Standard methods for addressing this requirement include the following:

 Provide a typical airflow of 100 linear feet per minute (LFM) / 0.5 linear meters per second

(as described in the section titled EPU-4460 Thermal Characterization, beginning on page

56) within the enclosure

 Position the EPU-4460 board to allow for convective airflow
 Lower the system level temperature requirement as needed

CPU Thermal Trip Points

The CPU cores in the Condor have their own thermal sensors. Coupled with these sensors are
specific reactions to three thermal trip points. Table 17 describes the three thermal trip points.
Note that these are internal temperatures that are about 10 ºC above the heat plate temperature.

Table 17. CPU Thermal Trip Points

Trip Point Description

Passive (Note 1)

Critical (Note 2)

Maximum core temperature

1. The default value in the BIOS Setup utility for this trip point is 90 ºC.

reduces the power draw and heat dissipation, but lowers the processing

These trip points allow maximum CPU operational performance while maintaining the lowest
CPU temperature possible. The long-term reliability of any electronic component degrades when
it is continually run near its maximum thermal limit. Ideally, the CPU core temperatures will be
kept well below 100 ºC with only brief excursions above.

CPU temperature monitoring programs are available to run under both Windows and Linux.
Table 18 lists some of these hardware monitoring programs.

Thermal Specifications, Restrict i ons, and Condi t ions

Graphical test data is in the section titled EPU-4460 Thermal Characterization, beginning on
page 56. Refer to that section for the details behind these specifications. These specifications are
the thermal limits for using the EPU-4460 with one of the defined thermal solutions.

Due to the unknown nature of the entire thermal system, or the performance requirement of the
application, VersaLogic cannot recommend a particular thermal solution. This information is
intended to provide guidance in the design of an overall thermal system solution.

Table 19. Absolute Minimum and Maximum Air Temperatures

Board With Heat Plate

Overall Restrictions and Conditions:

 Ranges shown assume less than 90% CPU utilization.
 Keep the maximum CPU core temperature below 100ºC.
 The ambient air surrounding the EPU-4460 needs to be maintained at 85 ºC or below. This

includes the space between the two main boards as well as the space beneath an installed
Mini PCIe expansion board. A required overall airflow of 100 linear feet per minute (LFM) /

0.5 linear meters per second (LMS) addresses this requirement. If this air flow is not
provided, other means must be implemented to keep the adjacent air at 85 ºC or below.

Heat Plate Only Restrictions and Conditions:

 The heat plate must be kept below 90 °C. This applies to a heat plate mounted directly to

another surface as well as when the HDW-408 heat pipe block is used.

Heat Sink Only Considerations:

 At 85°C air temperature and 90% CPU utilization, there will be little if any thermal margin

to a CPU core temperature of 100 °C or the passive trip point (see test data). If this is the use
case, consider adding a fan or other additional airflow.
