10 Gigabit Ethernet Architecture
The CPU-111-10 utilizes 10Gb Ethernet (10GbE) to provide high-speed interconnection paths between the CPU,
both XMC sites, the backplane, and a front panel SFP+ module. The 10GbE architecture is shown below.

Fulcrum FM3224 Switch
The FM3224 10GbE Switch is the heart of the CPU-111-10 SBC. Using 10Gb Ethernet, it connects the backplane to
the CPU, XMC Modules, and front panel SFP+ Fiber Optic I/O modules (not included with the CPU-111-10).
The FM3224 is a fully integrated single-chip wire-speed 10G Ethernet switch. In addition to enhanced layer-2
functionality, the FM3224 layer-3 capabilities include advanced classification, extensive congestion management, and
improved switch management flexibility.
Features of the FM3224 include:
300nS Latency
Advanced Policy Engine
Switch Virtualization and Scaling
Port and MAC Based Security
In-band Switch Management
Provides Full-Mesh connectivity between up to eight VPQ Node Boards
Support for Front Panel SFP+ Connector for Copper or Fiber Optic cables (Configuration
dependent)
