Power supply fan noise

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.
