Afternoon,

Having an issue with one of our 7048's. Has been working fine for quite sometime however after a power outage it now boots with the following:

It doesn't seem to know what model it is and will only show the management port also:

I've had a look around the web for some advice but most say it required a ticket into arista - which is not so helpful now as it is end of life.

Has anyone seen this before or had any success in rectifying the issue? I've tried reloading it from scratch however this alos doesn't appear to work.

Any help will be greatly appreciated!

Thanks.
