Yes! This is possible by using two SBM-GEM modules – either the switch (SBM-GEM-001), the pass-through (SBM-GEM-002) or even the new 1/10G Switch (SBM-GEM-X2C). There is a two-port Ethernet NIC chip on each Blade that is routed through the midplane to the two separate switch locations in the rear of the chassis – upper and lower left. That gives you two Ethernet LAN ports.
For the third you would need to install the SBM-XEM-002 – the 10G Ethernet Pass-Through module. This also requires an AOC-IBH-003 Mezzanine card on the Blade. With this you get the third LAN interface.
