4. Replace the bottom cover of the chassis.

# 2.5 Connecting DC Power

![This is a vertical image of a standard warning sign. At the top is a red equilateral triangle containing a white exclamation point in the center. Below the triangle is the text 'WARNING:' printed in black capital letters.](.dlap-401-xavier-50m-00076-1000-10/b91c426c5079cbe23be13a6fd66a6473afd9c9a3884ec4197e130b8b2aa58e8b.jpg)

Before providing DC power to the DLAP-401-Xavier, 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-401-Xavier 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 irré- versibles sur le système.

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

 IEC 62368-1 + IEC 60950-1 + UL 62368-1
 Output voltage: 24 VDC
 Output current: 6.67A minimum
 TMA: $6 0 ^ { \circ } \mathsf { C }$ minimum

The DLAP-401-Xavier DC power input connector uses V+, V-, and chassis ground pins and accepts input voltage as shown previously.

Customers may optionally order a DC power adapter from ADLINK.

# 3 Using the System

# 3.1 Software Configuration

The DLAP-401-Xavier 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 the ADLINK website:

https://www.adlinktech.com/Products/ Deep\_Learning\_Accelerator\_Platform\_and\_Server/ Inference\_Platform/DLAP-401-Xavier

# 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. Note the locations of DLAP-401-Xavier’s power, reset, and recovery buttons and complete the following steps on it before performing the host PC steps.

# Client (DLAP-401-Xavier):

1. Connect the OTG (Type-C) cable to the USB 3.0 port.
2. Press the power button to power on the device.
3. Press and hold the recovery button and then press the reset button.
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.

5. Now run the following commands in the directory that contains your downloaded L4T file:

```shell
# sudo tar xzvf mfi_jetson-xavier-&lt;version&gt;.tbz2
# cd mfi_jetson-xavier-&lt;version&gt;
# sudo ./nvmflash.sh
```

6. Allow the update to complete.

# 3.3 CAN Bus Configuration

By default, the DLAP-401-Xavier is configured to support the CAN bus protocol.

The loopback test commands are as follows:

```tcl
# ifconfig can0 down
# ip link set can0 type can bitrate 500000 dbitrate 20000000 berr-reporting on fd on
# ip link set up can0
# cansend can0 123#0101020300050607 //send data
