Narrative:
We were cruising at FL280 when I heard a buzzing noise coming from the floor on the captain's side that lasted a couple of seconds. Then my first officer and I smelled smoked in the flight deck. I told the first officer to put on [the] oxygen mask and smoke goggles. We accomplished the QRH checklist and [diverted to an alternate airport].after landing; maintenance told us the #2 avionics fan shorted out and that was what probably caused the smell of smoke and buzzing noise.
