Router Hardware Components
date_range
21-Mar-23
Junos OS runs on all Juniper Networks devices, including both routers and switches. This section focuses specifically on router hardware components.
Table 1 lists the major hardware components in each router series.
Note:
The ACX Series router is a single-board router with a built-in Routing Engine and one Packet Forwarding Engine. The “pseudo” FPCs and PICs are described in ACX2000 and ACX2100 Routers Hardware and CLI Terminology Mapping.

| Flexible PIC Concentrators (FPC) | X | X | X | X | |
| Physical Interface Module (PIM) | X | ||||
| Physical Interface Card (PIC) | X | X | X | X |
Flexible PIC Concentrators (FPCs) are each populated by PICs for various interface types. On some routers, the PICs are installed directly in the chassis.
For information about specific components in your router, refer to its hardware guide.
