The interconnects are
bay1: Brocade (B-series) fibre channel switch
bay3: 1Gb ethernat pass-tru (direct connection from the blade NICs to the module RJ-45 jacks)
bay5: Cisco network switch
The blades are likely BL460c G1 - the G1 is not mentioned for the first generation, look at the fron side, you should see BL460c only.
