Has any one seen an issue where you re-image a 5508-x with a known good copy FTD 6.2.3. You use the same IP for the managment NIC for TFTP and HTTP to install the image. Once FirePower is on the device you can not communicate to or from the managment interface.
Ifconfig and show network look good. Tcpdump shows the interface receiving broadcasts but not direct traffic.
I can ping the local IP from the host along with 127.0.0.1. No other hosts on the subnet can ping the FTD box. I have tried multiple cables, plugging direct to the box and multiple switches from 10MB to 1GB.
The thing that gets me is that the interface works great for TFTP and HTTP for the reimage - just not for final config.

I found the solution. The config register was set to 0x41 and should have been set to 0x1.
To fix I booted to rommon and executed the confreg command with showed the Current Configuration Register: 0x00000041
I issued the command: confreg 0x1
then issued the boot command

Thanks. Yes - different cables, different switch ports and even different switches. It is only FTD that is causing the issue. I re-imaged with ASA software and installed the SFR module and everything works great.
I have tried 3 different versions of ROMMON and 2 different versions of FTD.
Everything works as it should until the system boots the FTD image. I can not contact the 192.168.45.45 default IP nor the one I statically/dynamically assign after the first boot process.
I have done this hundreds of times before and this is the first time I have run into this issue.
Thanks for the responses.
