hi,

have seen and suffered from same.  nearby strikes can cause enough
surge to fry things.  best solution - air-gaps where possible between
devices (eg fibre to link switches),  surge protectors on ethernet
cables where needed (eg feeds from Access points) - and if the APs
have external antennae
then use lightning arrestors on the coax cables.

why main wireless vendors still don't do SFP/SFP+-based APs I don't
know... (would mean only the AP cooks and the edge switch isnt the
victim....
