Chapter 1. Overview 1
Chapter 1.Overview
The BullSequana Edge nano server addresses challenging AI workloads with a
strengthened design. It runs compute-intensive embedded AI predictive
analytics and computer vision applications for edge computing.
The server contains a Nvidia Volta GPU, which enables the inference of
complex AI models with lowest possible latency.
Its passive cooling system automatically manages its temperature.

Chapter 3. Initial installation and configuration 9
Chapter 3.Initial installation and configuration
The BullSequana Edge nano server is pre-installed with Ubuntu 18.04.
There are two operating modes for the server:
•Connecting a display, using the Ubuntu GUI and treating the server as a
desktop computer.
•Using a LAN connection and SSH, once the IP address is known. The
default behavior is that of a DHCP client.
The following steps apply to the first mode using the Ubuntu GUI, but the
commands will be exactly the same for the second mode that uses an SSH
connection.
3.1 Connecting the server
Procedure
1. Connect the keyboard, mouse and display (HDMI connector) to the
server.
2. Connect the power supply (19-24V DC) to the server.
The power supply can either be server AC converter (which can be
provided by Atos), or a DIN rail DC power supply (not provided by Atos).
3. Connect the network cable to the server.
The network cable will be needed to access the server from a host
system, for additional software installation.
4. The server boots.
This takes about 45 seconds.

3.2 Configuring the server for the first time
Procedure
1. Login to the server.
Username
Factory default: admin
Password
Factory default: Yop9e4rPb
Important It is strongly recommended to change the default user
password.
2. Configure the keyboard layout.
The keyboard default layout is QWERTY. This can be changed.
Example to set a French keyboard:
sudo setxkbmap fr
3. Configure the power mode.
The default power mode is 10W 2 Core, which is the lowest power mode.
The maximum is 15W 6 Core. This can be changed with the following
command:
sudo /usr/sbin/nvpmodel –m <power_mode_ID>
power_mode_ID: from 0 to 6. Refer to the following table:

4. Configure the IP address.
The DHCP client is active, the system gets an IP address automatically if
there is a DHCP server.
A SSH server is running.
5. Configure the time zone.
The default time zone is Asia/Taipei.

Chapter 3. Initial installation and configuration 11
Example to set the time zone to Europe/Paris:
sudo timedatectl set-timezone Europe/Paris
timedatectl status

3.3 Updating the system
Prerequisite
The Ubuntu repositories must be accessible.
Procedure
1. Update the system.
The OS is Ubuntu 18.04 and needs to be updated.
Run the commands:
sudo apt update
sudo apt upgrade
sudo apt autoremove
2. Remove the unused software.
Only 16 GB of eMMC storage is available for the basic configuration, which is
quite small.
Unused software can be removed to create more space following the upgrade.
Example:
sudo apt-get remove --purge libreoffice* thunderbird
sudo apt-get clean
sudo apt-get autoremove
