ANNEX B – Daemon Installation

To enable the Redfish API to retrieve system-level Ethernet interface data, a daemon must be installed on the host OS.

Supported Operating Systems

The current version of the daemon supports the following OS environments:

ERMI Daemon Version	Minimum ERMI Module Firmware Required	Remarks
1.0.6	1.0.2.0	Stable release from 2025 Q2
1.0.7	1.0.2.0	1. Correct the display text during installation. 2. Filter out inactive (disabled) network interfaces. 3.The daemon will be restarted after installation.
1.0.8	1.0.2.0	1. Supports Windows 11.

Note:
Please ensure firmware versions meet or exceed the minimum required versions to guarantee software compatibility and stability.

Download the Daemon Installer (Optional)

Please verify with your supplier whether the ERMI daemon is pre-integrated into the system environment.

If the ERMI daemon is not pre-integrated, contact our support team for further assistance.
Install the Daemon

After downloading the .deb file, install it using dpkg:
```
sudo dpkg -i ermidaemon-<version>-ubuntu-arm64-jp6.deb
```
If there are missing dependencies, run:
```
sudo apt-get install -f
```

Enable and Start the Daemon

sudo systemctl enable ermidaemon
sudo systemctl start ermidaemon

Check if the daemon is running:

systemctl status ermidaemon

If installed correctly, the daemon will expose host-side NIC information to the Redfish API endpoint:

/redfish/v1/Systems/{SystemId}/EthernetInterfaces

To stop and remove the daemon service from the system:

sudo systemctl stop ermidaemon
sudo systemctl disable ermidaemon
sudo dpkg -r ermidaemon

If you also want to remove configuration files:

sudo apt-get purge ermidaemon

And to clean up unused dependencies:

sudo apt-get autoremove

To check logs for the daemon service:

journalctl -u ermidaemon
