Do you have the latest RSC and OBP firmware installed as well as any/all
picld patches for the OS?

I'm assuming when you do a prtdiag it is showing all the fans at 100%?

The Fire280 does not have an RSC board installed (I read somewhere that
this is why `uname -a` reports the unit as a Blade 1000). I have the
same version of Solaris 10 (the ??/05 version not the 6/06 version)
installed on an actual Blade1000 and on the Fire280 and on the Blade it
moderates the fans as soon as the OS has booted, on the Fire it does not.

Is picld running on the Fire280? If not, try starting it:

# /usr/lib/picl/picld

Yes, picld is running on both the Fire280 and the Blade1000; I agree
that it is likely that this daemon controls the fans. What I don't
understand is the different behavious; both machines identify and
Blade1000.

I suppose that there is a configuration file somewhere which contains
different information for the two types of housing.

Any pointers to its location would be welcome.
