[SunHELP] HW Question

[Jan Jansta]

Hi folks,

I am having hard times with a Sun E450 Server.

This message appears on the console few seconds after booting solaris kernel and all fans stop working. 

-----------
write  to PCF8574 (FPM) failed   addr=7
read from PCF8574 failed
-----------

As far as I am concerned this migh be caused by an hw error on power distribution board, but I would like to be pretty sure befor I will pay for new one.

Any suggestions are appreciated

Jan
