Physical Interface Modules Overview

A Physical Interface Module (PIM) is a network interface card that is installed on a J-series Services Router, to provide physical connections to a LAN or a WAN. The PIM receives incoming packets from the network and transmits outgoing packets to the network. Each PIM is equipped with a dedicated network processor that forwards incoming data packets to the Routing Engine, and receives outgoing data packets from the Routing Engine. During this process, the PIM performs framing and line-speed signaling for its medium type.

PIMs are not hot-swappable. You must power off the Services Router before removing or inserting a PIM.

For a complete list of supported PIMs, see Table 14.

For information about network interfaces, see the interfaces overview and configuration information in the J-series Services Router Basic LAN and WAN Access Configuration Guide.
