<p>One thing I'm remembering from E450 boot is that it goes into Jet
Engine mode pretty early on. The fans should be going full speed
and I think they stay on until the OS takes over and steps them
down based on actual tempurature conditions.<br>
</p>
<p>If the fans aren't roaring that's probably diagnostically
relevant.<br>

<br>
I am trying to get the E450 that I mentioned previously
running. It was running in the data center at work until
it was decommissioned a couple months ago.<br>
<br>
I collect and rescue sun3 desksides and sun4c and sun4m
workstations but have no experience with the E450.<br>
<br>
When I turn on the power switch on the back, both power
supplies show green LEDs but nothing happens as I turn
the front panel switch key through the different
positions. It has a frame buffer (PGX32) but I am using
the serial console. Nothing appears there.<br>
<br>
Any suggestions?<br>
<br>
