I/O Module Port Mapping-Four-Bay Chassis - Dell PowerEdge FX2 Owner's Manual

– To establish optical links between two 10 Gb pass-through modules, an external rack switch must
be used as an intermediary. Direct optical connection (using SFP modules, SFP+ modules, and
Directed Attach Copper cables) between two 10 Gb pass-through modules is not supported.
NOTE: This restriction is not applicable for Direct Attach Copper connections or to the 1 Gb
pass-through module.
NOTE: For more information on the I/O modules, see the I/O module documentation at Dell.com/
poweredgemanuals.
I/O module port mapping—four-bay chassis
The following I/O module port mapping options are available on the four-bay chassis configuration that
supports up to four half-width compute sleds.
NOTE: In the four-bay PowerEdge FX2s configurations that support storage sleds mapped to
compute sled(s), the I/O module ports are mapped only to the compute sled(s). If storage sleds are
installed, the corresponding ports on the I/O modules mapping to these slots are not active.
Figure 16. I/O module port mapping—half-width compute sleds with dual port NDC
A half-width compute sled that is configured with dual port Network Daughter Card (NDC) is mapped to
a single port on each I/O module. The following table lists the compute sleds and the ports to which they
are mapped.
