There was a recent power outage in my neighborhood. Now that the power has been restored, my access points do not have power. The power light on the switch is Green but the system light is Amber. I have tried to reboot by removing the power cord and pressing the reset button. Thanks!
Based on your description, it seems that the Switch (ICX7150 Switch) is stuck in boot mode after power interruption, so the unit will not pass any kind of traffic, in order to fix the problem, you will have to perform a software recovery which requires, two connections between your ICX to a computer, I am going to advise use a window because the steps are easier, one connection will be the console connection, using a type C/USB cable, where the type C will be connected to the ICX7150 Switch and the USB to your computer, finally the second connection will be a regular Ethernet cable connected between the computer and the out-of-band management port on your Switch, don't worry because the following guide will explain in detail the step by step.
