Hi Sergio,
I have the loud PSU fan problem with this redundant PSU chassis also.
Seems to be a seating problem with the PSUs and the cage...
If we firmly seat the PSUs in the slots we can "temporarily" fix the problem of PSU fan/(s) ramping up intermittently.
But if the server gets transported / moved the problem re-appears.
When the problem occurs, the server shows no alert status (the status LED is solid green - no problems reported), however one of the PSU fans is spinning at a very high RPM.
if you then re-seat the PSU, it silences the fans, and all is OK again.
This problem has occurred in 3 different new servers for us.
Is there a chance there is a known Firmware or Physical Hardware problem with these PSU & Cages
(Please note i've had the PSUs and cage replaced by Intel and the problem still exists)
Thanks,
Rob.
