Unable to ping B2250 blades

I do have a cluster IP set, and each blade (only 1 blade per chassis currently) has a management IP set. Both the cluster IP and management IP are on the same subnet. I am reading over your comment about the dedicated management interface not being bridged internally and am trying to understand what and where I need to make changes. I have one external trunk configured but the only VLAN's I have defined are for the 'peernet' and another internal subnet. Still struggling to understand why I cannot ping the blades management IP's from each other.
