Cannot Login to Firepower 2100 Series Device

[iwearing]

Hi,

I have been working in the Lab on an HA pair of 2120 Firepower devices.

After Lab testing I have re-imaged both devices with the base install software package. Both boot successfully and I am presented with "firepower login:" prompt.

I can Login in to one of the devices using admin/Admin123 credentials. However I am unable to Login to the other device, as soon as I enter the admin username I am told that the Login is incorrect and immediately presented with the "firepower login:" prompt again with no option to enter the password.

Any suggestions would be appreciated to recover from this problem.

thanks

Hi,

Can you try and restart the device?
I have noticed that there might be a bug that clears on a restart.
Could be this bug, but can't access the bug information at the moment:

Hi Micke,

I did try powering off/on but unfortunately this did not resolve the issue.

Same problem Login fails as soon as I enter the administration username.

I would recommend you to open a case with Cisco TAC.

I had the same problem.  The resolution  was to Perform a Factory Reset from ROMMON.  The guide as follows:
