There are a lot of resources on the web about how to run the IMPI tool from another computer on your network (a Linux client for example). Like
here. But I still find it strange that choosing another profile has no effect at all. There is something you could try. Within IPM view choose the profile you want ("optimal" for example) and update it. If the change has no effect then go to the Cold Reset Button and reset the BMC (Baseboard Management Controller). It might work and can't do any harm. It's just a reset of the BMC without resetting the whole server.
