Within the Dell Modular Server Chassis unit, blade switches manage traffic to and from up to two HCA
IB mezzanine cards on the hosts. Each HCA IB mezzanine card adds two IB ports to a host. Each HCA
port connects through the unit mid-plane to a particular blade switch slot. The IB ports of the HCA card
that is seated in the HCA B location, connect to I/O module bays B1 and B2. The IB ports of the HCA
card that is seated in the HCA C location, connect to I/O module bays C1 and C2. See
Figure 2
