MX104 Interface Modules
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:
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
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 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

Each transceiver has one pair of port LEDs. Table 1 describes the LEDs in more

The data cable has been disconnected from the port.
The interface has been disabled, or the 10GbE port does not have the required license.
MX104 Port and Interface Numbering
Identifying Interface Numbers on the Hardware
Each MX104 router has three built-in MPCs, which are represented in the CLI as FPC 0 through FPC 2. The numbering of the MPCs is from bottom to top (see Figure 1).
The port numbers on MICs correspond to the port numbers on the interface. The port numbering on the MIC-3D-20GE-SFP-EH MIC depicted in Figure 1 is only one example of the port numbering for MICs.
Each MIC might number ports differently—horizontally or vertically, for example—and it is important to review the port numbering for your particular MIC in the MX Series Interface Module Reference.
MPC 0 and MPC 1 have two slots each that accept MICs. The MICs
are represented as MIC 0 and MIC 1 in the CLI and are logically divided into PICs
depending on their type. A MIC installed in the left-most MIC slot
1/0) is represented
in the CLI as PIC 0 and PIC 1. A MIC installed
in the right-most MIC slot (
1/1) is represented as PIC 2 and PIC 3.
MPC 2 houses a 4-port 10-Gigabit Ethernet MIC. Both the MPC and the MIC are considered fixed and are built into the front panel of the chassis. The MPC is represented as FPC 2 in the CLI. The MIC is represented as MIC 0 in the CLI and is logically divided into a single PIC, which is represented as PIC 0.
Table 2 summarizes the relationship between the components and the interface names.

Identifying Interface Numbers in the CLI
In the physical part of the interface name, a hyphen (-) separates the media type from the MPC number (represented as an FPC in the CLI), and a slash (/) separates the logical PIC and port numbers:
type—Media type, which identifies the network device. For example:
ge—Gigabit Ethernet interface
xe—10-Gigabit Ethernet interface
For a complete list of media types, see Interface Naming Overview.
fpc—Slot in which the MPC is installed. On the MX104 router, the three MPCs are built into the chassis and are represented in the CLI as FPC 0, FPC 1, or FPC 2.
pic—Logical PIC on the MIC. The number of logical PICs varies depending on the type of MIC.
The MIC number is not included in the interface name.
The following sample CLI output displays the three built-in MPCs and five MICs.
