ICX7450 lost IP address after firmware update to 08.0.30h and serial console shows no signs of life

Hi,
I've upgraded the firmware of our ICX7450-24P (primary image) and after reboot the switch works normally but it is no longer reachable at his IP address.

The serial console shows no signs of life after connecting to it with a Wirenest Console Cable (for use with ICX7250, ICX7450 ICX7750 Switches aftermarket replacement for 50-1000122-01 https://www.amazon.com/Wirenest-Console-Brocade-ICX7250-Switches/dp/B0BF5Z5X8Z ) and with a tested USB to serial adapter. 

Do you have any suggestions for getting the console back?

Can a factory defaults reset fix it?

Is there a way to start with the secondary image without interacting with the serial console?

Many thanks in advance.

It's a bit messy if I am being honest (much easier on newer models). Here is what it normally looks like:

Just to be clear, the box is passing traffic just fine? If so, I would assume fastiron is loaded.

Sorry but I missed the button "Load more replies" and had not seen replies.

Yes I agree that is a little bit messy, new models with a USB-C or RJ45 serial console are way better. 
The traffic is passing fine, I suppose too that fastiron is loaded.
We have some strange effect but at the moment is not so important, I don't know how to detect it without accessing the switch.
Would you recommend doing a factory reset?

Many thanks in advance

Tomorrow I'll be on-site so I could give it a try.

The only reason I would factory reset would be to have it pull a dhcp address. That would allow you to know the IP address from the dhcp server. Then you could possibly telnet/ssh to it.
