Cisco ASA5520 cooling issue

LM_GROUP asked

Last Modified: 2012-06-25
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?

You are not alone.

I mount it according to the airflow needs and use patch panels if I have to for cables.

I just had the same problem.
It took about 5 minutes to take the top off and turn the fans around.
The hardest part was getting the plastic grill off the front to get to the fan mounting screws.

Works great now.
