Power Core has no on/off switch and starts automatically when power is applied. The system can also be restarted remotely using a Web UI or Telnet connection, see Power Core - Restarting the System.

The boot-up progress is shown on the front panel:
  1. First, the SYSTEM display and STATUS LED are black and unlit.
  2. Then, the Lawo logo appears and the STATUS LED lights in white.
  3. As soon as boot-up is complete, the Welcome page appears and the STATUS LED starts to blink; its color reflects the sync status.


If the STATUS LED does not start to blink, then the device has an internal problem. Please reboot the device (using the RESET button) as a first step.

At the end of the boot-up, Power Core loads the latest settings (stored at shut-down). This is known as the warm start data, and it means that the system returns to whatever the settings were at the last power off.

There are two exceptions: PTP parameters that have been edited using the Web UI and output stream parameters that are changed during runtime via Ember+. In this instance, the changes are not warm start persistent and the parameters reset to the values stored in the configuration.

Please note: 

  • If you perform a cold start, then the system ignores the warm start data and resets all settings to the default values stored in the configuration.
  • If this is the first time you have powered the device "out of the box", then the system loads a very basic configuration that allows Power Core to boot. To get the system operational, you will need to upload the standard configuration or a custom configuration using the ON-AIR Designer.

Powering Off / Shutdown

There is no special shutdown procedure for the hardware. So, to power down, turn off the mains power.
