Sun V880 not starting after transport

Hi,

I moved recently and we had to carry my v880 around. Now it doesn't  
start anymore. Power supplies show green on AC, after switching  
machine on also on DC, so can be assumed working fine. Cardcage  
lights are fine, but maintenance lights in CPU cage don't come on.  
Also, only power light lights up, but the other two won't do  
anything. Anyone an idea what the problem could be?

Regards

Dirk
