WARNING:

Risk of physical injuries and / or property damage:

When mounting the device, use the screws to mount the VESA bracket to the rear of the device. Tighten all four screws firmly to support the weight of the device. Make sure that the suspension system is capable of carrying the device.

![A yellow triangular warning sign with a thick black border, containing a large black exclamation point in the center.](.sp2-ehl-50m-p1400-1010-11/ae9f5f82598d3157370c4cd9211c9b854de36201043cdc9dc5e94fce38f967b9.jpg)
CAUTION:

Risk of burns to the user caused by hot surfaces:

Turn off power and allow the device to cool down prior to per- forming any mounting or demounting operations. Do not touch the enclosure for over 10 seconds when the device is in operation or is still hot from previous use.

![A white document icon featuring horizontal black lines is overlaid with a large red checkmark.](.sp2-ehl-50m-p1400-1010-11/72b1bcf1fd71f401ecf3fd98d44cf9f87d2694bef79552078b16f2acafbaadff.jpg)
NOTE:

All dimensions are in millimeters, unless noted.

# 4.3.1 Panel Mounting

The SP2-EHL Series can be panel mounted with 14 mounting clips (optional items sold separately). Make sure there is adequate space behind the panel for ventilation, and that the panel material and thickness can support the weight of the device.

Step 1: Cut the panel opening using the appropriate cutout dimensions.

Step 2: Attach I/O cables to the device before installing into the panel if rear access will be limited after installation.

Step 3: Place the device into the panel cutout.

![Diagram showing two rectangular panels with a red arrow indicating direction, no text or symbols present](.sp2-ehl-50m-p1400-1010-11/f9441ec95aced5ad422ce83db93707f503f5b955b4b9dcff248e2e99b62bac9a.jpg)

Step 4: Insert the mounting clips into the slots on the sides of the device as shown. Hand-tighten the mounting clips with a Phillips- head screwdriver to secure it to the panel. Do not overtighten the clips to avoid damaging the device enclosure.

# 7 BIOS Settings

The Basic Input/Output System (BIOS) is a program that provides a basic level of communication between the processor and peripherals. In addition, the BIOS also contains codes for various advanced features applied to the SP2-EHL Series. The BIOS setup program includes menus for configuring settings and enabling features of the SP2-EHL Series. Most users do not need to use the BIOS setup program, as the SP2-EHL Series ships with default settings that work well for most configurations.

![The image displays a standard warning symbol: a red triangle with a white exclamation point centered inside. Below the triangle, the text reads 'WARNING:'.](.sp2-ehl-50m-p1400-1010-11/847762d76e747acea5b2318a4b18e45cb03292fe9dafe54e8c921b113e8e1e58.jpg)

Changing BIOS settings may lead to unexpected system behavior and the possible inability to boot.

![The image displays an icon of a document with a folded top-right corner and faint horizontal lines. A large, red checkmark is superimposed over the document. Below the icon, the text 'NOTE:' appears in black, uppercase letters.](.sp2-ehl-50m-p1400-1010-11/1f4a7d0b2eae6bd2ce3fb3fbe81d968b0107cd9b3afa2a1d25118ef8cbadffd1.jpg)

BIOS options used in this manual are for reference only, and are subject to change. Users can download the latest BIOS version from the ADLINK website.

# 7.1 BIOS Setup Menu

The BIOS Setup Utility is invoked by pressing &lt;ESC&gt; or &lt;DEL&gt; when the system boots. A system reboot is required when changes are made in the BIOS Setup Utility.

The BIOS Setup Utility includes the following hotkeys.

• &lt;F1&gt;: General help
• &lt;F8&gt;: Load previous BIOS values
• &lt;F9&gt;: Load BIOS default values
• &lt;F10&gt;: Save & Exit the Setup Utility

# 7.1.1 Menu Conventions

The appearance of the setup menus and items listed in this chapter are based on a VT100 terminal connection via serial console with the following menu conventions.

Using brackets
Editable menu options are marketed with square brackets, ‘[‘ and ‘]’.

# 8.1 Driver Installation Steps

Follow the driver installation steps below:

1. Fully install Microsoft Windows before installing any drivers. Most standard I/O device drivers have been included in Microsoft Windows. For Windows 10 IoT Enterprise users, Administrator privilege is required to install the drivers.
2. Install the chipset driver.
3. Install the graphics driver.
4. Install the Ethernet driver.
5. Install the Management Engine driver.
6. Install the Serial I/O driver.
7. Install the DI/O Driver.

# 8.1.1 VGA Noise Issues with Older Versions of Ubuntu OS.

The VGA port may exhibit noise when the system is running an older version of the Ubuntu OS. This is due to a graphics driver compatibility issue with the new Intel Atom® CPU (which is reproducible on the Intel Customer Reference Board). ADLINK recommends installing the latest version of Ubuntu (e.g., 14.04 LTS).
