Have you defined your VLAN to the external ports? This is starting to sound more like a networking issue from the chassis switches to your core network switches than a blade configuration issue.
Couple more questions:
1. Do you have an FSM? If so, are you able to ping its external mgmt address on ETH1?
2. Do you have your hosts in a cluster? If so, are you able to ping between your VMs on each host? Also, if question #1 is yes, can you ping your FSM from a VM?
