[rescue] Starting a Sun E450

Hi,

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.

I collect and rescue sun3 desksides and sun4c and sun4m workstations but have no experience with the E450.

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.

Any suggestions?
