ACX4000 Modular Interface Card (MIC) Overview

Modular Interface Cards (MICs) install into two slots in the front of the ACX4000 router and provide the
physical connections to various network media types. The slots are labeled 1/0 and 1/1. You can install
MICs of different media types on the same router as long as the router supports those MICs. For
complete specifications, see the
MICs receive incoming packets from the network and transmit outgoing packets to the network. During
this process, each MIC performs framing and high-speed signaling for its media type. Before transmitting
outgoing data packets through the MIC interfaces, the PFE encapsulates the packets received.
MICs are hot-removable and hot-insertable.
