Juniper Networks E320, E120 manual Broadband

Page 2

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 10-Gigabit Ethernet, Ethernet, Asynchronous Transfer Mode (ATM), and Packet over SONET (POS) interfaces.

The placement of these system components are as shown.
