Completely disable all fans on UCS C series

[Mikey Boy]

Hi, we are looking to run a trial on some test UCS servers that we have whereby they are run under full immersion for data centre deployments. 

This has already been proved with 2 other server manufacturers but not yet with the USC platform. 

We need to completely disable all of the fans via CIMC but I cannot seem to do this at first glance?

there is no option for that. if you want you can simply remove fans (with care) and test. but that will give errors at booting.

IT can be done but the developers, as well as, the Cisco AM/SE needs to be involved in. 

The developers will need to provide a patch that will enable the motherboard to boot up without the need to detect the fans.  

Good luck.

Thank you, I reached out to TAC and got a closed door. Will go to the SE now and try that route.
