First boot and configuration

After installing JelinaOS, a few steps bring the device into normal operation on its first boot.

1. Connect to the network

After the device starts, connect it to the network as follows:

• Wired network: Plug in an Ethernet cable to obtain an address automatically.
• Wireless network: Connect to Wi-Fi using the system network configuration.
• View the address: After logging in, use system commands to view the current network address.

Network access is required for cloud registration and update checks, except for standalone use.

2. Log in to the device

The following methods are available for the first login:

Method	Description
Local terminal	Connect a monitor, keyboard, and mouse for local login
Remote SSH login	Log in over the network, suitable for headless environments

Factory default credentials

Environment	Account	Password
Terminal / SSH	root	jelina
Desktop	jelina	jelina

Security notice: Factory default credentials are intended only for initial access. Change the default password before normal use and avoid using default accounts in production.

3. Check system status

After logging in, verify the system version and operating status. To view versions:

jelina-ver --all

To view the device overview:

jelina-info

This command presents key device information in one place:

• System version, kernel version, and system purpose (development/production).
• Device agent status and version.
• Cloud connection status (Online) and the local update confirmation setting.
• Current boot partition (A/B) and boot target.

Use it to quickly confirm whether the device is operating normally.

4. Verify cloud registration (cloud-managed mode)

If device configuration was included during flashing, the device automatically registers with JelinaCloud after connecting to the network:

1. Open JelinaCloud and navigate to the device’s fleet.
2. Confirm that the device is online in the device list.
3. Open device details to view its status, running services, and logs.

Registration typically takes no more than 30 seconds. If the device remains offline, check network connectivity and configuration file correctness.

Devices without configuration embedded in the image can register locally using the device-side tool through the license registration route. Advantech provides the serial number:

jelina-manual-register --check       # Check registration status
jelina-manual-register <serial-number>      # Set the serial number and start registration

For complete registration methods in disconnected or private networks, see device registration and connectivity.

5. Basic security configuration

Before putting the device into service, we recommend:

• Change the default login password.
• Configure firewall rules as needed and open only necessary ports.
• In production mode, access the device only through the cloud’s secure channel, without opening public Internet ports.
• Regularly update the system and security patches through the cloud.

6. Next steps

Your device is ready. You can now:

• Deploy your first application — Try deploying containerized and native applications.
• Manage applications — Learn about the full range of application deployment capabilities.
• Update the system — Understand the system update mechanism.
