Cisco ASA5520 cooling issue
Posted on 2009-02-11
This may seem like an odd question, but has anyone had any issue with the air flow direction of the cooling fans in an ASA5520? Is there a way to reverse the fans direction? They blow from back to front and I would prefer them to blow the other way to keep the cool isles cool and the hot isles hot. In order to do this I would have to mount the plastic side to the back, but this places my interfaces forward and I cant see them while mounted in a rack and it wouldnt get the best air flow. Has anyone found a good way to keep ASAs cool in an enclosed rack without having to mount them backwards?
