R7000 Brick with 4 ethernet port leds flashing

[zviruss]

Hi,

My new purchased R7000 is having this issue:

Turned on... only four (at once) of the ethernet port leds are flashing. I can only ping router for short amount of time. Serial port does not work.

Again.. Power led NEVER goes on.

It looks like some sort of loop. I wonder why cant get to CFE? And router gets connected via 192.168.1.1 only for up to 10 seconds.

Any suggestions will be very appreciated.

Thx
Tomas

If you bought it new, return/exchange it. Never a good sign when that happens brand new. 

Otherwise if it was "new" from someone else, then you could try tftp/nmrp flash to fix. 

are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through.

and if that doesn't work, you can try using nmrpflash

I did my lesson. COM port is not working.... I have tried ALL possible ways... including nmrpflash...

Anyone seen same thing - ONLY 4 ethernet ports flashing - I guess hardware fault...

I just want to confirm it was HARDWARE fault. Nothing else. I can fix firmware issue but not hardware...

Thx
