was everything powered-on in correct order ? (DAEs, SPS , DPE ..etc)

Are the SPs booted up ?

yes, the SP's were booted and appeared to be working properly.  waited until the amber flashing light went to a steady blue, then powered on the data movers.  watched them go through their boot up sequence and then powered up control stations.  but then i noticed that the data movers had gone back to booting.   from my control station getreason gives

0 - slot_0 reset

10 - slot_1 primary control station

0 - slot_2 reset

0 - slot_3 reset

Was there any interruption in physical connectivity ?

Was the shutdown a graceful one ?

it was not a graceful shutdown.   physical connections between the system have not been modified.  Is there a way to terminal in to the data movers to see what's going on and/or reset them?
