e450 failure

Dear managers,

When our enterprise 450 produced RED state exception errors (throughout,
even on reboot), we purchased another motherboard (for 4 480 MHz CPUs with
8MB cache), after Sun's advice. Lo and behold, the problem still exists (saw
it once, on the first boot):( So I'm afraid it's one (or more) of the CPUs
causing problems (really should have guessed that in the first place).
However, when I removed a CPU or two, (in fact, now after placing everything
back the current problem is the same - ), nothing comes up on the console or
monitor. In fact, I only get a green light on the status LED indicating
power (only), no POST or general activity at all.

Does this happen for < 4 CPUs when you do not place a filler in the empty
CPU slots? Or am I doing something really wrong? Perhaps it's a loose
connection somewhere but I'm not sure where to look. All help is
appreciated, and I will summarize.
