MX104 Modular Interface Card (MIC) Overview
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 Packet Forwarding Engine encapsulates the packets received.
The MX104 routers support the following types of MICs:
•
Front-Pluggable MICs on page 47
•
Built-in 10-Gigabit Ethernet MIC on page 47
•
MIC LEDs on page 49
Front-Pluggable MICs
Modular Interface Cards (MICs) install into four slots in the front of the MX104 router and
provide the physical connections to various network media types. MICs are hot-removable
and hot-insertable. The slots are labeled 0/0, 0/1, 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 “MICs Supported by MX Series Routers” on page 49 in the
MX Series Interface Module Reference.
Built-in 10-Gigabit Ethernet MIC
The built-in 10-Gigabit Ethernet MIC is fixed on the MX104 router. The MIC is labeled XE
and is located on the front panel.
NOTE: If you ordered a license for the built-in 10-Gigabit Ethernet ports on
the MX104 and you do not receive a paper license with your shipment, open
a casewith customersupport.See “Contacting CustomerSupport” on page203
