The default license is for the 2-core 2.4 GHz configuration. The core license for the 4-core and 8-core processor configurations
are available on factory shipped systems.
Depending on the processor core license on your system, the system BIOS displays the maximum number of cores per processor
on your system. For instance, if you have a license for an 8-core processor configuration, the system BIOS displays the
maximum cores per processor as 8.
Networking configurations
The LAN On Motherboard (LOM) network provides Ethernet connectivity from the pass-through modules (PTM) on the FX2
enclosure to the sleds in the enclosure. The network traffic from the nodes in an FM120x4 sled to the pass-through modules
on the FX2 enclosure is routed through a network switch that is embedded on the sled system board. Each FM120x4 sled in
the enclosure maps to two ports on each pass-through module. For more information, see the Dell PowerEdge FX2 and FX2s
Enclosure Owner's Manual at Dell.com/poweredgemanuals.
There are four networking configurations supported on the FM120x4 system. You can select the network configuration from the
CMC web interface. All FM120x4 sleds in the FX2 enclosure have the same network configuration. For more information on the
networking configurations supported on your system, see Dell.com/poweredgemanuals.
Standard configuration
In this configuration, the uplink ports from the embedded network switch on a sled and the four uplink ports on the enclosure
pass-through modules (PTM) to which the sled maps are configured in a single trunk group or Link Aggregation (LAG). The
ports on the external switches to which the enclosure pass-through modules connect must be configured into a single trunk
configuration or LAG. Alternatively, spanning tree must be run on the external rack switches to disable three of the four uplink
ports.

NOTE: The image shows two external rack switches. However, the standard configuration also supports uplinks of all four
ports to a single external rack switch.
