Lan Led flashing yeallw non stop - Max HD4 cat4

I have a problem with a max HD4 (cat 4) ; as soon as I plug the power, all the LAN led are flashing in yeallow, non stop.
I can’t reset the router, and I can’t log to it.

Did someone else already encourter such a problem ?
Any idea how to solde it ?

Thanks for ideas


Never seen this before but it sounds power related. Are you using the original power AC - DC power supply or powering in a different way? What is the output voltage and power of the supply you are using?

I am using the original power supply and don’t have any other to try.
I need to wait
Hopefully it’s just this point :frowning:
thanks to you
