In case anyone has troubles getting into BMC like me due to DHCP issues, try reconfiguring it in Bios. Mine was set to a static IP outside my subnet range, and the management NIC was configured to be one of the SFP+ ports. Go to:
Bios -> Server Mgmt -> BMC Network Configuration
From there set the NIC to "Dedicated NIC" (this maps to the one RJ-45 gigabit jack on the server) and set dhcp configuration to "dynamic on next reset". From there reboot and give it 5min to start BMC. You should be able to return to that bios screen to see the IP that was assigned by DHCP.
