Intel NUC Board/Kit NUC7i5DN Technical Product Specification

NOTE

To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be

populated with SO-DIMMs that support the Serial Presence Detect (SPD) data structure. This

allows the BIOS to read the SPD data and program the chipset to accurately configure memory

settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to

correctly configure the memory settings, but performance and reliability may be impacted or the

SO-DIMMs may not function under the determined frequency.

NOTE

Intel NUC Board NUC7i5DNBE supports only 4 Gb and 8 Gb memory technologies (also referred to

as “SDRAM density”). Table 3 lists the supported SO-DIMM configurations. Table 4 lists the SO-

DIMM configurations that are not supported.

1.5.1.5.2

Configuration Modes

Video mode configuration for eDP displays is supported as follows:

•

Panel: automatic panel identification via Extended Display Identification Data (EDID) for

panels with onboard EDID support

•

Predefined: panel selection from common predefined panel types

Custom payloads: custom EDID payload installation for ultimate parameter flexibility,

allowing custom definition of EDID data on panels without onboard EDID

In addition, BIOS setup provides the following configuration parameters for internal flat panel

displays when a display is connected prior to booting:

•

Color Depth: allows the system integrator to select whether the panel is 24 bpp with VESA or

JEIDA color mapping, or 18 bpp.

Product Description

•

eDP Interface Type: allows the system integrator to select whether the eDP panel is a single-

lane, dual-lane, or quad-lane display.

eDP Data Rate: allows the system integrator to select whether the eDP panel runs at

1.62 Gb/s, 2.7 Gb/s, or 5.4 Gb/s.

Inverter Frequency and Polarity: allows the system integrator to set the operating frequency

and polarity of the panel inverter board.

Maximum and Minimum Inverter Current Limit (%): allows the system integrator to set

maximum PWM%, as appropriate, according to the power requirements of the internal flat

panel display and the selected inverter board.

NOTE

Support for flat panel display configuration complies with the following:

1. Internal flat panel display settings will be preserved across BIOS updates.

2. Backlight inverter voltage option “Vin” refers to board input voltage as provided to board

power input connector.

1.5.1.6

EDID Emulation Modes

The board supports emulation of displays so that the system may be remotely accessed in a

headless configuration, or be capable of tolerating display connectivity interruptions without the

operating system redetecting and rearranging the overall display layout. The display emulation

feature may be enabled in BIOS Setup (Advanced → Video → “Display Emulation” drop down

menu), with the following options:

•

“No display emulation” (default selection): the system operates normally.

“Headless display emulation”: provides a virtual display when no displays are connected to

the HDMI ports. The system creates a virtual 1280x1024 display when it boots with no

displays connected.

•

“Persistent display emulation”: The purpose of Persistent Display Mode is to "emulate" that

both displays are always connected. Persistent Display Mode prevents the GFX engine from

automatically reassigning the content of a temporarily disconnected display to the

remaining display. When Persistent Display Mode is selected the EC asserts that both HDMI

ports are always connected to a display no matter their actual connection status. The EDID

information from each display will remain programmed through S3, S4, and S5 power

states, until the feature is disabled or a power cycle event (G3 global state) occurs.

NOTE

“Persistent display emulation” is not compatible with HDCP 2.2 displays.

When using “Persistent display emulation” it would be expected behavior for the system not to

properly drive displays different than those connected when the feature was enabled, as the EDID

parameters of the initially connected displays are still being driven by the system. In order to

retrain “Persistent display emulation” with a different display configuration a power cycle (AC

power loss) is required.

Intel NUC Board/Kit NUC7i5DN Technical Product Specification

Addressable Memory

The system has been validated with up to 32 GB of addressable system memory. Typically the

address space that is allocated for PCI Express configuration space, BIOS (SPI Flash device), and

chipset overhead resides above the top of DRAM (total system memory). On a system that has 16

GB of system memory installed, it is not possible to use all of the installed memory due to system

address space being allocated for other system critical functions. These functions include the

following:

•

Connectors and Headers

CAUTION

Only the following connectors and headers have overcurrent protection: back panel USB, front

panel USB, and internal USB headers.

All other connectors and headers are not overcurrent protected and should connect only to

devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these

connectors or headers to power devices external to the computer’s chassis. A fault in the load

presented by the external devices could cause damage to the computer, the power cable, and the

external devices themselves.

Furthermore, improper connection of USB header single wire connectors may eventually overload

the overcurrent protection and cause damage to the board.

This section describes the board’s connectors and headers. The connectors and headers can be

divided into these groups:

•

Front panel I/O connectors

Back panel I/O connectors

On-board I/O connectors and headers (see page 45 and 46)

NOTE

Unless otherwise noted, all 2.0 mm headers are dual-row, straight, surface mount with each two-

pin section measuring 2.0 mm x 4.0 mm, with a pin height of 4.0 mm.

Power Switch Header

Pins 6 and 8 can be connected to a front panel momentary-contact power switch. The switch

must pull the SW_ON# pin to ground for at least 50 ms to signal the power supply to switch on or

off (the time requirement is due to internal debounce circuitry on the board). At least two seconds

must pass before the power supply will recognize another on/off signal.

NOTE

Pin 6 is designed for momentary contact switches only. It is not recommended to permanently

hardwire the signal high or low because it can damage the board.

2.2.4.3 Power Supply Connectors

The board has the following power supply connectors:

•

External Power Supply – the board can be powered through a 12-24 V DC connector on the

back panel. The back panel DC connector is compatible with a 5.5 mm/OD (outer diameter)

and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12-24 (±10%) V DC and the

shell is GND. The maximum current rating is 10 A.

NOTE

External power voltage, 12-24 V DC, is dependent on the type of power brick used.

Intel NUC Board/Kit NUC7i5DN Technical Product Specification

•

Internal Power Supply – the board can alternatively be powered via the internal 12-24 V DC

2 x 2 power connector, where pins 1 and 2 are +12-24 (±10%) V DC and pins 3 and 4 are

GND. The maximum current rating is 10 A.

The connector used is Molex Micro-Fit (3mm pitch), right-angled, 4-pos/dual row (2x2).

2.4 Intel® Management Engine BIOS Extension (Intel®

MEBX) Reset Header

The Intel® MEBX reset header (see Figure 16) allows you to reset the Intel ME configuration to the

factory defaults. Momentarily shorting pins 1 and 2 with a jumper (not supplied) will accomplish

the following:

•

Return all Intel ME parameters to their default values.

Reset the Intel MEBX password to the default value (admin).

Unconfigure Intel AMT.

CAUTION

Always turn off the power and unplug the power cord from the computer before installing an

MEBX reset jumper. The jumper must be removed before reapplying power. The system must be

allowed to reach end of POST before reset is complete. Otherwise, the board could be damaged.

NOTE

After using the MEBX Reset, a “CMOS battery failure” warning will occur during the next POST.

This is expected and does not indicate a component failure.

NOTE

The MEBX_RESET header has a non-conductive protective cap installed. This must be removed

before installing the MEBX_RESET jumper, and reinstalled before reassembling the system. Failure

to do so may result in inadvertent shorting of the bottom cover screw to the header during bottom

cover reassembly (see Figure 16).

2.6.1

Power Supply Considerations

System power requirements will depend on actual system configurations chosen by the

integrator, as well as end user expansion preferences. It is the system integrator’s responsibility to

ensure an appropriate power budget for the system configuration is properly assessed based on

the system-level components chosen. See Section 2.2.4.3 Power Supply Connector for more

information.

•

The back panel input range is 12-24 V DC

The internal power connector input range is 12-24 V DC

CAUTION

The external DC jack is the primary power input connector of Intel NUC Board NUC7i5DNBE.

However, the board also provides an internal 2 x 2 power connector that can be used in custom-

developed systems that have an internal power supply. The internal 2 x 2 power connector is a

Molex Micro-Fit (3mm pitch), right-angled, 4-pos/dual row connector.

There is no isolation circuitry between the external DC jack and the internal 2 x 2 power connector.

It is the system integrator’s responsibility to ensure no more than one power supply unit is or can

be attached to the board at any time and to ensure the external DC jack is covered if the internal 2

x 2 power connector is to be used. Simultaneous connection of both external and internal power

supply units could result in potential damage to the board, power supplies, or other hardware.

2.7 Thermal Considerations

CAUTION

Failure to ensure appropriate airflow may result in reduced performance of both the processor

and/or voltage regulator or, in some instances, damage to the board.

All responsibility for determining the adequacy of any thermal or system design remains solely

with the system integrator. Intel makes no warranties or representations that merely following the

instructions presented in this document will result in a system with adequate thermal

performance.

CAUTION

Ensure that the ambient temperature does not exceed the board’s maximum operating

temperature. Failure to do so could cause components to exceed their maximum case temperature

and malfunction. For information about the maximum operating temperature, see the

environmental specifications in Section 0.

CAUTION

Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do

so may result in shorter than expected product lifetime.

Table 28 provides maximum case temperatures for the components that are sensitive to thermal

changes. The operating temperature, current load, or operating frequency could affect case

temperatures. Maximum case temperatures are important when considering proper airflow to

cool the board.

Table 28. Thermal Considerations for Components

Component

Maximum Case Temperature

Processor

For processor case temperature, see processor datasheets and processor

specification updates

To ensure functionality and reliability, the component is specified for proper operation when

Case Temperature is maintained at or below the maximum temperature listed in Table 29. This is

a requirement for sustained power dissipation equal to Thermal Design Power (TDP is specified

as the maximum sustainable power to be dissipated by the components). When the component is

dissipating less than TDP, the case temperature should be below the Maximum Case

Temperature. The surface temperature at the geometric center of the component corresponds to

Case Temperature.

It is important to note that the temperature measurement in the system BIOS is a value reported

by embedded thermal sensors in the components and does not directly correspond to the

Maximum Case Temperature. The upper operating limit when monitoring this thermal sensor is

Tcontrol.

Note: The operating temperature of the board may be determined by measuring the air temperature from the junction of

the heatsink fins and fan, next to the attachment screw, in a closed chassis, while the system is in operation.

Note: Before attempting to operate this board, the overall temperature of the board must be above the minimum

operating temperature specified. It is recommended that the board temperature be at least room temperature

before attempting to power on the board. The operating and non-operating environment must avoid condensing

humidity.

CAUTION

If the external ambient temperature exceeds 40 ^oC, further thermal testing is required to ensure

components do not exceed their maximum operating temperature.

3 Overview of BIOS Features

3.1 Introduction

The board uses Intel Visual BIOS that is stored in the Serial Peripheral Interface Flash Memory

(SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the Visual

BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and

Plug and Play support.

The BIOS displays a message during POST identifying the type of BIOS and a revision code. The

initial production BIOSs are identified as DNKBLi5v.86A.

The Visual BIOS Setup program can be used to view and change the BIOS settings for the

computer. The BIOS Setup program is accessed by pressing the <F2> key after the Power-On

Self-Test (POST) memory test begins and before the operating system boot begins.

NOTE

The maintenance menu is displayed only when the board is in configure mode. Section 2.3 on

page 57 shows how to put the board in configure mode.

3.2 BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 16 MB flash memory device.

3.3 System Management BIOS (SMBIOS)

SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in

a managed network.

The main component of SMBIOS is the Management Information Format (MIF) database, which

contains information about the computing system and its components. Using SMBIOS, a system

administrator can obtain the system types, capabilities, operational status, and installation dates

for system components. The MIF database defines the data and provides the method for

accessing this information. The BIOS enables applications such as third-party management

software to use SMBIOS. The BIOS stores and reports the following SMBIOS information:

•

BIOS data, such as the BIOS revision level

Fixed-system data, such as peripherals, serial numbers, and asset tags

Resource data, such as memory size, cache size, and processor speed

Dynamic data, such as event detection and error logging

Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS

information. The BIOS supports an SMBIOS table interface for such operating systems. Using this

support, an SMBIOS service-level application running on a non-Plug and Play operating system

can obtain the SMBIOS information. Additional board information can be found in the BIOS under

the Additional Information header under the Main BIOS page.

3.4 Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating system’s USB

drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and

to install an operating system that supports USB. By default, Legacy USB support is set to

Enabled.

Legacy USB support operates as follows:

1. When you apply power to the computer, legacy support is disabled.

2. POST begins.

3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and

configure the BIOS Setup program and the maintenance menu.

4. POST completes.

5. The operating system loads. While the operating system is loading, USB keyboards and mice

are recognized and may be used to configure the operating system. (Keyboards and mice are

not recognized during this period if Legacy USB support was set to Disabled in the BIOS

Setup program.)

6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are

recognized by the operating system, and Legacy USB support from the BIOS is no longer

used.

To install an operating system that supports USB, verify that Legacy USB support in the BIOS

Setup program is set to Enabled and follow the operating system’s installation instructions.

Overview of BIOS Features

3.5 BIOS Updates

The BIOS can be updated using one of the following methods:

•

Intel® Express BIOS Update utility, which enables automated updating while in the Windows

environment. Using this utility, the BIOS can be updated from a file on a hard disk, a USB

drive, a CD-ROM, or from the file location on the Web.

Intel® Flash Memory Update Utility, which requires booting from DOS. In order to boot from

DOS the legacy boot option in the BIOS has to be checked. Using this utility, the BIOS can be

updated from a file on a hard disk or a USB drive.

Intel® F7 switch during POST allows a user to select where the BIOS .bio file is located and

perform the update from that location/device. Similar to performing a BIOS Recovery without

removing the BIOS configuration jumper. The F7 switch supports FAT, FAT32, and NTFS

format storage.

•

Intel® Visual BIOS has an option to update the BIOS from a valid .bio file located on a hard

disk or USB drive. Enter Intel Visual BIOS by pressing <F2> during POST.

Both utilities verify that the updated BIOS matches the target system to prevent accidentally

installing an incompatible BIOS.

NOTE

Review the instructions distributed with the upgrade utility before attempting a BIOS update.

3.5.2

BIOS Recovery

It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the

BIOS could be damaged. Table 31 lists the drives and media types that can and cannot be used

for BIOS recovery. The BIOS recovery media does not need to be made bootable.

Overview of BIOS Features

3.6 Boot Options

In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive,

removable drive, or the network. The default setting is for the optical drive to be the first boot

device, the hard drive second, removable drive third, and the network fourth.

NOTE

Optical drives are not supported by the onboard SATA connectors. Optical drives are supported

only via the USB interfaces.

3.6.1

Network Boot

The network can be selected as a boot device. This selection allows booting from the onboard

LAN or a network add-in card with a remote boot ROM installed.

Pressing the <F12> key during POST automatically forces booting from the LAN. To use this key

during POST, the User Access Level in the BIOS Setup program's Security menu must be set to

Full.

3.6.2

Booting Without Attached Devices

For use in embedded applications, the BIOS has been designed so that after passing the POST,

the operating system loader is invoked even if the following devices are not present:

•

Video adapter

Keyboard

Mouse

3.6.3

iSCSI Boot

iSCSI is available on Dawson Canyon and can be configured in two different ways to achieve

different functions. The first can be used to configure iSCSI boot. This functionality is accessible

through the BIOS Setup Menu on the “Add-in Config” tab. The second can be used to configure

disk array access through the network via SCSI commands in Windows OS. The menu for this

option can be found under Control Panel > Administrative Tools > iSCSI Initiator.

3.6.4

Changing the Default Boot Device during POST

Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu

displays the list of available boot devices. Table 32 lists the boot device menu options.

3.6.5

Power Button Menu

As an alternative to Back-to-BIOS Mode or normal POST Hotkeys, the user can use the power

button to access a menu. The Power Button Menu is accessible via the following sequence:

1. System is in S4/S5 (not G3)

2. User pushes the power button and holds it down for 3 seconds

3. The system will emit three short beeps from the front panel (FP) audio port, then stop to

signal the user to release the power button. The FP power button LED will also change from

Blue to Amber when the user can release the power button.

4. User releases the power button before the 4-second shutdown override

If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where

possible.

At the point where Setup Entry/Boot would be in the normal boot path, the BIOS will display the

following prompt and wait for a keystroke:

[ESC] Normal Boot

[F2]

[F3]

[F4]

[F7]

Intel Visual BIOS

Disable Fast Boot

BIOS Recovery

Update BIOS

[F10] Enter Boot Menu

[F12] Network Boot

[F2] Enter Setup is displayed instead if Visual BIOS is not supported.

[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.

[F9] Remote Assistance is only displayed if Remote Assistance is supported.

If an unrecognized key is hit, then the BIOS will beep and wait for another keystroke. If one of the

listed hotkeys is hit, the BIOS will follow the indicated boot path. Password requirements must

still be honored.

If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the

system.

Overview of BIOS Features

3.7 Hard Disk Drive Password Security Feature

The Hard Disk Drive Password Security feature blocks read and write accesses to the hard disk

drive until the correct password is given. Hard Disk Drive Passwords are set in BIOS SETUP and

are prompted for during BIOS POST. For convenient support of S3 resume, the system BIOS will

automatically unlock drives on resume from S3. Valid password characters are A-Z, a-z, and 0-9.

Passwords may be up to 19 characters in length.

The User hard disk drive password, when installed, will be required upon each power-cycle until

the Master Key or User hard disk drive password is submitted.

The Master Key hard disk drive password, when installed, will not lock the drive. The Master Key

hard disk drive password exists as an unlock override in the event that the User hard disk drive

password is forgotten. Only the installation of the User hard disk drive password will cause a hard

disk to be locked upon a system power-cycle.

Table 33 shows the effects of setting the Hard Disk Drive Passwords.

Table 33. Master Key and User Hard Drive Password Functions

Password Set

During every POST, if a User hard disk drive password is set, POST execution will pause with the

following prompt to force the user to enter the Master Key or User hard disk drive password:

“Enter Hard Disk Drive Password:”

Upon successful entry of the Master Key or User hard disk drive password, the system will

continue with normal POST.

If the hard disk drive password is not correctly entered, the system will go back to the above

prompt. The user will have three attempts to correctly enter the hard disk drive password. After

the third unsuccessful hard disk drive password attempt, the system will halt with the message:

“Hard Disk Drive Password Entry Error”

A manual power cycle will be required to resume system operation.

NOTE

As implemented on Intel NUC Board NUC7i5DNBE, Hard Disk Drive Password Security is only

supported on either SATA Port 0 (M.2) or SATA Port 1 (onboard SATA connector). The passwords

are stored on the hard disk drive so if the drive is relocated to another computer that does not

support Hard Disk Drive Password Security feature, the drive will not be accessible.

Intel NUC Board/Kit NUC7i5DN Technical Product Specification

3.8 BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and who can

boot the computer. A supervisor password and a user password can be set for the BIOS Setup

program and for booting the computer, with the following restrictions:

•

The supervisor password gives unrestricted access to view and change all the Setup options

in the BIOS Setup program. This is the supervisor mode.

The user password gives restricted access to view and change Setup options in the BIOS

Setup program. This is the user mode.

If only the supervisor password is set, pressing the <Enter> key at the password prompt of

the BIOS Setup program allows the user restricted access to Setup.

If both the supervisor and user passwords are set, users can enter either the supervisor

password or the user password to access Setup. Users have access to Setup respective to

which password is entered.

•

Setting the user password restricts who can boot the computer. The password prompt will be

displayed before the computer is booted. If only the supervisor password is set, the

computer boots without asking for a password. If both passwords are set, the user can enter

either password to boot the computer.

•

For enhanced security, use different passwords for the supervisor and user passwords.

Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 16 characters in

length.

•

To clear a set password, enter a blank password after entering the existing password.

Table 34 shows the effects of setting the supervisor password and user password. This table is for

reference only and is not displayed on the screen.
