Jazil,  It sounds like you installed and iDrac6 Enterprise card without the iDrac Express being installed. When upgrading a system from the Baseboard Management Controller to an iDRAC6 Enterprise Controller, a iDRAC6 Express Controller must also be installed for functionality of the iDRAC Enterprise Controller.  This is due to the majority of the logic for the iDrac actually resides in the Express. Also, what is the part number for the Enterprise card you installed, so I can confirm the compatibility. I ask as I have part numbers for the Express card alone to use with the Enterprise you already have, as well as a part number for the entire upgrade from BMC to Enterprise. Thats in case the card you have isn't compatible.   iDrac6 Express alone (for upgrade from BMC to Express) - 330-5946  If card you have isn't compatible- iDrac Enterprise Upgrade Kit (for upgrade from BMC up to the Enterprise - 330-7645  Let me know.
Hi, I installed a new  IDRAC 6 card and during startup i got this message BMC communication failure and  i have no access to IDRAC utility. Thank you for your help in advance.
