I got a used hp 2920-48g j9728a switch and heard that I can put it into operation.
I have to reset it - unfortunately I can't do that.
If I want to do the following:
1. the " Reset " and the "Clear" button is activated
2. hold the "Clear" button and release the "Reset" button.
3. when the test LED starts to flash, release the "Clear" button.
4. after the self-test with the factory settings.
unfortunately it does not work - in my case the "Test LED" does not start flashing.
What am I doing wrong - or can I do war differently?
