This bit of information was given to me a little while ago, and since then it has been extremely helpful a couple of time. This should work with any SG switch, (not sure about V switches as I have not tried it before).
To factory reset a ShoreTel Switch:
- connect to the switch via a Serial connection, (baud rate 19200)
- Reboot switch
- take the option to stop auto boot and then type:
> bootc static flash vxworks
The switch will now reboot and start-up as if it was a brand new switch! Any questions please use the comments field below.
