# 2 Getting Started

# 2.1 Unpacking Checklist

Before unpacking, check the shipping carton for any damage. If the shipping carton and/or contents are damaged, inform your dealer immediately. Retain the shipping carton and packing materials for inspection. Obtain authorization from your dealer before returning any product to ADLINK. Ensure that the following items are included in the package.

▶ DLAP-301 unit
▶ Screw pack
▶ Terminal block for DC input
▶ Remote power control cable
▶ Wall mount kit (plus optional DIN rail kit if applicable)

# 2.2 Cooling Considerations

All heat-generating components of the DLAP-301 are located on the top side of the system. These components directly contact the heat sink via thermal pads to dissipate heat. To maximize efficiency of heat dissipation, maintain a minimum of 2 inches (5cm) clearance from the top of the DLAP-301.

# 2.3 Removing the Chassis Cover

To access the DLAP-301's internal components, remove the heat-sink as follows.

1. On the front panel, remove all nuts.

3. Press down on the module until it is seated, then secure it to the board using two M2.5-P-head-L5 screws (not provided).
4. Attach the wires and antennas that came with your Wi-Fi kit.
5. Reassemble the SATA drive bracket, front panel, and heat-sink.

# 2.5 Connecting DC Power

![The image features a red triangular warning sign with a white exclamation mark in the center. Below the triangle, the text 'WARNING:' is written in black capital letters.](.dlap-301-50m-00044-1000-10/0a3f1989d1c2ca05f04caa99750b46dee4fb9b0334a8ddba60a98294e54db62f.jpg)

Before providing DC power to the DLAP-301, ensure the voltage and polarity provided are compatible with the DC input. Improper input voltage and/or polarity can be responsible for system damage.

Avant de connecter le PC DLAP-301 à une source de courant continu, veuillez vous assurer de la polarité de la tension conformément à l'entrée CC du PC. Une tension et/ou une polarité incorrectes peuvent causer des dommages irréversibles sur le système.

DC power sources must comply with ES1 circuits as well as the following:

▶ IEC 62368-1, IEC 60950-1, and UL 62368-1
▶ Output voltage: 12V DC
▶ Output current: 20A minimum
▶ TMA: 50°C minimum

The DLAP-301 DC power input connector uses V+, V- pins and accepts a 12V DC input. Customers may optionally order a DC power adapter from ADLINK:

▶ DC plug with lock (Part No. 31-62164-1010-A0)
▶ Power adapter cable (Part No. 30-21714-0000-A0)

# 2.6 Power Mode Switch

The DLAP-301 supports an extended remote power button. Switch jumper CN25202 to set the power button as remote.

# 3 Using the System

# 3.1 Software Configuration

The DLAP-301 ships with a customized NVIDIA Linux for Tegra (L4T) image pre-installed. The latest version of this custom L4T image and other relevant files are available on our website.

# 3.2 System Recovery

You will need a Linux host PC (Ubuntu is recommended) in order to flash your client device with a new system image. Complete the following steps on the client before performing the host PC steps.

# Client (DLAP-301):

1. Connect the OTG cable to the USB 2.0 port.
2. Press the reset and recovery buttons at the same time.
3. Press the power switch.
4. Release the reset button.
5. Release the recovery button.

# Host PC:

1. Install Python 2.7, python-minimal (or equivalent packages) and qemu-user-static on the host PC.
2. Connect the host PC to the client via OTG cable.
3. Open a terminal on the host PC and run this command:
# lsusb
4. Look for "NVidia Corp." in the output (an example is circled in red in the screenshot below). If found, the host PC recognizes the client and you may proceed. If not, double-check the OTG cable connection and perform troubleshooting as needed until the client is recognized.
