Nexus 5596UP - Change of Airflow

Hi

is it possible to change the airflow of a 5596UP from  front-to-back to back-to-front (reverse airflow)  without affecting the service? I consider to exchange the existing power supplies and fans one by one in a short period of time.

Will it affect the service? I would guess not. The only problem I see, is that the airflow during the time, when FANs and power supplies are swapped, will be not efficient enough to cool the system. (Sorry, I don't have lab gear to test with :-)

Any thoughts on this?

Many thanks!

Hi - 

 

Thanks, Mark. Looking at other threads it seems it is "sometimes" possible if the replacement fans/PSU's are done quickly enough. (I gather you get a 60 second period to replace them all). 

However, as you say, probably best to power off, replace components and then power back on. 

Regards, 

James
