Hello --- attempting to recover a WS-12-250DC that field techs reported "may" have gotten the power cut to it during F/W update.
Started to attempt recovery via console, got this initial result:
- Code: Select all

Read through the forum thread on this topic and saw the following post that seemed to be related to a user reporting a similar symptom:

Gave that a try, but ^C doesn't seem to have any effect on breaking the boot sequence (when prompted) and the boot process continues. After a couple of reboots and attempts, boot process now appears to hang here:

And no longer ends on the 'admin@Netonix_Switch:/#' prompt.
In fact, the terminal is now hanging and non-responsive at 'mini_fo_d_release: no private data.'
Tried it both in Hyperterminal and PuTTY for the sake of doing so --- same result.
Thoughts? Time to RMA or am I missing something?
Thanks!
