Is there an option to replace only the power supply or type of fans to reverse the air flow? This would be much easier than unracking and recabling everything.</P> Fri, 26 Mar 2021 15:48:42 GMT cmansfield 2021-03-26T15:48:42Z https://live.paloaltonetworks.com/t5/general-topics/pa-3220-power-supply-air-flow-direction-optional/m-p/394361#M91122 <P>As I have encountered and many others may also, when this unit was installed in a data center, the person did not follow hot and cold isle standards.
