Urgent! FTD 1140 upgrade failed and cannot access via COM

NetworkPitu — Mon, 28 Apr 2025 08:52:58 GMT

I need really urgent help. I upgraded our Cisco FTDs to new recommended version but one of them get failed and now it can't boot to system. Even I don't have access to COM and enter to ROMMON mode for recovery. It looks like entire OS failed and bootloaded not working. I tried to factory reset with button in front of device but also nothing happen. Like entire OS is down and I can't restore or even re-build OS. Please any tips or solution what can I do? I have a recent backup from FMC so I just need to make FTD works, connect again to FMC and restore backup

For an issue like this, and to ensure both prompt response and continuous support, I highly recommend you contact support/Cisco TAC.

When contacting TAC for this, I recommend you observe the LEDs on the appliance (green, yellow, red, stable/blinking, etc etc) to have at hand.

It is hard to provide any pointers without some additional and more detailed information. E.g., screenshot of the console output, exact error message (if any). If the appliance is just completely unresponsive and you do not get anything from the console then it is probably best to raise a request with TAC. An RMA request (if you have active support contract) will most likely be needed.

Thank you for rating helpful posts!

There is no error message just a blank screen on serial console. It connects me but screen is frozen and blank. I tried this cable on other FTD and it worked.

So I think OS is completely down. I putted SPA file in to USB and tried on old FTD and it automaticaly started recovery from this file. So an 1h ago I plugged it to corrupted FTD 1140 and just left it. I am going to check. If not then I will probably contact TAC because it appears to be more deeply issues which is impossible to fix by myself

Definitely a case for TAC. Sounds like hardware failure to me.

I have exactly the same issue.
Could you solve it?
Did you need TAC support?

It was hardware issue. I sent to RMA and I got replaced device.

If you are able to flash FTD you can try to re-image it.
