Basically, due the power outage the switch went to a state that we called (boot-mode) that is not able to boot up properly.
That does not mean is broken or need to be replace 'in some cases'
1-Please try to disconnect from the Power outlet the ICX-7150 and reconnected.
2-Please try to press the reset button using a paper click or a small stick
- Remove power from the switch.
- Press and hold the Reset button while applying power to the switch.
- After all the system LEDs flash amber, release the Reset button.
If that does not make any difference, we need to perform a software recovery since it can be that the image flash is corrupted so in basic words the unit is not able to boot up properly and need re-install the image to boot up properly.
3-We need to access (physical) using one of the cables to the ICX-7150C12P mentioned on the below guide:
How to console in the ICX-7150-12cp
Once we are there, we can try to boot up the unit using the following commands:
Boot_primary or Boot_secondary
If that step does not work Software recovery needs to be applied
Here is the guide:
