NION locking up or rebooting spuriously
If you load a role onto a NION and find that the unit has locked up, or keeps rebooting
spuriously, it may not be possible to erase the role via the front panel or the web interface using
the normal methods.
The NION includes a service menu, accessible at boot time, which will allow you to boot the
unit, but not load the role. It can then be erased.
Caution: It is very important that you follow the instructions in this section carefully. Do not
experiment with other options in the service menu. You could make the NION inoperable.
To stop the role from loading automatically at boot time
1. Switch off the NION by pressing the Power button, and then selecting OK.
2. Hold down the two buttons indicated below.
3. While holding down the buttons, press the Power button to switch the NION back on.
This menu will be displayed.

4. Turn the wheel clockwise until BOOT MODE is displayed.
5. Push the wheel button.
6. Turn the wheel to select QUIET, then push the wheel button to select the option.
7. Press Attn.
The NION will boot. You will then be able to erase the role without running it.
8. Reboot the NION.
The NION will start in NORMAL boot mode.
