The E320 and the E120 share a system architecture and common components:
•Switch route processors (SRPs) perform system management, routing table calculations maintenance, forwarding table computations, and other control plane functions.
•Switch fabric modules (SFMs) create a distributed shared memory switching fabric.
•Line modules (LMs) are frame processing and forwarding engines for I/O modules.
•Power modules distribute redundant power feeds through the system to all components.
•I/O adapter modules provide the physical connection to the network via
The placement of these system components are as shown.
