I just booted my firepower II up after moving last month. When I did, magic smoke started coming out if the pinitech NVRAM module I had installed. Specifically the small chip on the underside of the NVRAM module was toast. Any idea what could have cause this? No other obvious damage, when it first booted it seemed fine. Burned up after about 30 seconds of being on. What should I check before installing new ram and booting again?
