lost password netgear fsm7328ps switch

Hi All,

I bought a secondhand netgear fsm7328ps switch and it appears that it's admin password is not resetted before it was shipped. The selling person doesn't know either what it should be as he has just bought 10 of these switches in Bulk.

Is there by chance a way to factory reset those things without login into the console?

I hope so, otherwise this this will become a pile of useless metal.
