Why it alarms?

Thanks a lot, problem is solved

"All installed fan modules must blow air in the same direction and must match the airflow direction of the installed power supplies."

from.....
http://documentation.extremenetworks.com/summit/summit_family_hw_install/replace_fan/c_airflow-direc...

So you'd need to replace the
10927 - 550W AC Power Supply module for Summit switches, Back-to-Front airflow
with
10925 - 550W AC Power Supply module for Summit switches, Front-to-Back airflow

Thanks for quick answer!
Yes slot 1-3 is 17111
and PSU both are 10927
summit 17103
Directions must be equal?

I'm not an expert but as the alarm show "Air flow mismatch" could it be that the chassis that was ordered isn't populated with the correct PSUs.

I.e. if you go to page 8 the chassis for order number 17201 is for airflow "front to back" so you must make sure that you also order "front to back" PSUs.

Could you confirm that you've the correct ones installed.
