C8200L Edge - can’t break to ROMMON prompt?

[geto25]

I’ve searched high and low and haven’t been able to find an answer to this.

I was doing a routine software upgrade on a brand new Cisco C8200-1N-4T this afternoon and everything seemed fine until the reboot. Once rebooted, it’s giving a failure stating:

Process: 125 ExecStart=/initramfs_module_load.sh (code=exited, status=1/FAILURE) … Failed to connect to bus: No such file or directory

So fine, I figure the install got corrupted or something similar, I just need to hop into ROMMON and boot the IOS file manually. But how do I get to a ROMMON prompt?

The router has no physical buttons other than the power switch at the back, tried sending break at all points during the boot process with no luck.

I’ve got a TAC case opened up but can anyone help steer me in the right direction here? Thanks in advance for any replies.

Console into the router and reboot.

Post the entire boot-up process so we can see what is going.

what Terminal client you using, most of the time we use putty use serial console. with the below config on the console settings:

9600 baud rate

No parity

8 data bits

1 stop bit

No flow control

with the above CTRL+BREAK should work.

or as @Leo Laohoo  mentioned post complete boot logs here.

other note: what version of code before what version of code you upgraded to ?
