Hello,

a few days ago i had at home a power down.
i have 2 RB2011UiAS-2HnD-IN one is the router one is a accesspoint/switch
the last one keeps bootlooping after powerup.
also resetting for netinstall not working
the other RB2011UiAS-2HnD-IN is just fine.
In de defect 2011 displays first:
routerboot
loading kernel
starting kernel
then a beep and a reboot then and its start all over.
When turning on with reset button pushed i get:
ether boot
routerboot configuration
ether boot
loading kernel from nand
and again a reboot
netinstall not working then also.

ps i was at the latest routeros 6.42.5
ps2 when ik connect serial i see a kernel panic

Have you tried another power supply?

yes,

at the moment i try with a working 2011 netinstall to work
and that works (same power supply) and i see at the terminal he got a bootp adress
But the defect one not get a ip from bootp

edit:
oke the info as above that a other got a ip adres was tested with a laptop.
so i going back to my pc where i used netinstall and ik got no ipadress.
next step, try again but now from the laptop!
