I/O module port mapping—four-bay chassisThe following I/O module port mapping options are available on the four-bay chassis configuration that supports up to fourhalf-width compute sleds.NOTE: In the four-bay PowerEdge FX2s configurations that support storage sleds mapped to compute sled(s), the I/Omodule ports are mapped only to the compute sled(s). If storage sleds are installed, the corresponding ports on the I/Omodules mapping to these slots are not active.Figure 16. I/O module port mapping—half-width compute sleds with dual port NDCA half-width compute sled that is configured with dual port Network Daughter Card (NDC) is mapped to a single port on eachI/O module. The following table lists the compute sleds and the ports to which they are mapped.Table 7.

I/O module port mapping—half-width compute sleds with quad port NDC/network outputA half-width compute sled configured with quad-port NDC is mapped to two ports on each I/O module.A half-width compute sled with four compute nodes is configured with a quad-port network output, which is mapped to twoports on each I/O module. The network traffic from the nodes in the compute sled to the I/O modules in the enclosure is routedthrough a network switch that is embedded on the compute sled system board.
