Hi have inherited 8 p2260 switches, 2 are fine as admin password is standard/default. the other 6 have been changed,

I just need to reset to factory defaults to reset the admin password so i can reconfigure them.

I have physical access to all switches so can enter diagnostic mode (by removing internal jumper) but do not know what command to issue to initiate a full factory reset.

On these switches there is no physical reset button etc.

any help appreciated
