Did you enable IPMI over Lan in the BMC/DRAC config?

The way I understand the documentation:

1. Access the DRAC web interface. (Only available through the DRAC NIC port.)
2. Telnet Console.  (Only available through the DRAC NIC port.)
3. RACADM. (Remote via -r through DRAC NIC, or locally.)
4. SSH Interface. (Same as Telnet, just encrypted.)
5. IPMI Interface - Provides access through the DRAC 5 to the remote system's basic management features. The interface includes IPMI over LAN, IPMI over Serial, and Serial over LAN. (Available trough server NIC.)

 Through the server NIC you have IPMI capabilities only. To access DRAC only features you have to connect through the DRAC NIC.
