Hi markgu, The R610 does come with the iDRAC6 express. Do you have NIC1 connected? That is the NIC it uses in shared mode. The enterprise upgrade adds support for the dedicated NIC port.
I've assigned a static IP configuration to several R610 via CTRL-E.  None of these machines have the optional iDRAC enterprise card installed. For love or money, I cannot ping these machines, and I've tried everything. However, my question is this.  Is iDRAC Express integrated into the R610?  I think it is but the evidence at the moment (several machines) suggests that it doesn't work.  We plan to purchase the Enterprise card shortly but it would be good to at least use the Express functionality until then. Incidentally, EVERY server reports "No Active LOM found" at the moment. Thanks.
R610 iDRAC. Integrated?
