I tried the power cycle previously and it did not work.  The problem was solved. I did not see the full solution, but it required using the server’s SD Card drive to update the IDRAC.   Hopefully that will help some of you move in the right direction. 
I have a Dell PowerEdge R720 running Server 2008 R2.  I was doing an SUU update to fix a display issue and included other updates.  The update had a red x next to the Bios and IDRAC.  After a restart, I ran into the IDRAC issue.  Fans are running at full speed.  I tried powering down and installing the bios/idrac through Support Assist. No luck.  I would appreciate any guidance. 
After SUU update, IDRAC fails to initialize and LifeCycle Controller is disabled
