Steps 1 to 3 are a good discription of a unit with AC restored and the BMC booting.
Steps 4 to 6 are the start of the DC power-on phase of the main processors.
Steps 4 & 5 are the normal, but a "hang" is not.
Do you get any POST LED activity after Step 4?
If so which of the 8 POST leds are lit when teh system hangs?
You can try a CMOS clear http://download.intel.com/support/motherboards/server/s5000pal/sb/s5000pal_s5000xal_tps_r2_0.pdf Pg 60
which will do a global restore to the BIOS defaults settings.
Thank you for the reply. There is no post activity whatsoever. When the power button is set there is no change other than the fans spining up. They simply turn on to a constant speed. I tried clearing the CMOS jumper as well. Thanks again - Dan
After substituting everything I substituted the PS. The board now goes through power up on the bench. The next step is to move the board and PS back to the 'cabinet'. Can someone reccomend a good standard PS for these boards. They are sensitive to PS, a clean supply is necessary for reliable operation. Thanks, Dan
