MX5, MX10, MX40, and MX80 Interface Modules

MX5, MX10, MX40, and MX80 Modular Interface Card Description

Modular Interface Cards (MICs) provide the physical connections to various network media types. 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 router encapsulates the packets received.

On the fixed MX80 chassis, the MICs come preinstalled and cannot be replaced.

On the modular MX5, MX10, MX40, and MX80 chassis, you can install a variety of MICs in the two front slots of the router, and the optional Multiservices MIC can be installed in the rear slot.

Figure 1: MICs Installed in an MX5, MX10, MX40, and MX80 Router

The MX5, MX10, MX40, and MX80 routers support the following types of MICs:

• Front-Pluggable MICs

• Fixed (Built-in) MICs

Front-Pluggable MICs

You can install and remove MICs in the MX5, MX10, MX40, and modular MX80 chassis. The MIC slots are labeled 1/MIC 0 and 1/MIC 1. Each MIC slot has an ejector handle located above the MIC slot.

You can install MICs of different media types as long as the router supports those MICs. For complete specifications, see MICs Supported by MX Series Routers.

Port and Interface Numbering on the MX5, MX10, MX40, and MX80 Routers

Each modular MX5, MX10, MX40, and MX80 router is capable of having the components shown in Figure 2.

Figure 2: MX5, MX10, MX40, and MX80 Interface Port Mapping

1 — MIC slot 1/0 (FPC 1, PIC 0 and PIC 1)	3 — 10-Gigabit Ethernet ports (FPC 0, PIC 0)
2 — MIC slot 1/1 (FPC 1, PIC 2 and PIC 3)

The chassis has two built-in MPCs, which are represented in the CLI as FPC 0 and FPC 1.

MPC 0 (FPC 0) contains a 4-port 10-Gigabit Ethernet MIC. Both the MPC and the MIC are considered fixed and are built into the front of the chassis. The MIC is represented as MIC 0 in the CLI and is logically divided into a single PIC, which is represented as PIC 0.

MPC 1 (FPC 1) has two slots, which accept up to two 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 MIC slot 1/0 is represented in the CLI as PIC 0 and PIC 1. A MIC installed in MIC slot 1/1 is represented as PIC 2 and PIC 3.

MX80 series routers also contain a MIC slot in the rear of the chassis that supports the optional Juniper Networks Multiservices MIC. The Multiservices MIC installed in the rear MIC slot is represented in the CLI as FPC 0, MIC 1, and PIC 2. The port number for the rear slot in the MX80 chassis is 0.

The port numbers on the MICs correspond to the port numbers in the interface. See the MX Series Interface Module Reference for more information on specific MICs.

Table 6 summarizes the relationship between the components and the interface names.

Port and Interface Numbering on MX80-48T Routers

Each MX80-48T router contains two built-in MPCs, which are represented in the CLI as FPC 0 and FPC 1 (see Figure 3).

Figure 3: MX80-48T Interface Port Mapping

MPC 0 (FPC 0) contains a 4-port 10-Gigabit Ethernet MIC and is built into the front of the chassis. The MIC is represented as MIC 0 in the CLI and is logically divided into a single PIC, which is represented as PIC 0.

MPC 1 (FPC 1) contains a 48-port Tri-Rate MIC and is built into the front of the chassis. The MIC is represented as MIC 0 in the CLI and is logically divided into four PICs, which are numbered 0 through 3. Each logical PIC on the built-in Tri-Rate MIC contains twelve ports, which are numbered 0 through 11 (see Figure 3).

Table 7 summarizes the relationship between the components and the interface names.

MX5, MX10, MX40, and MX80 Modular Interface Card LEDs

The fixed 10-Gigabit Ethernet Modular Interface Card (MIC) has link LEDs located on the front panel. For more information about the link LEDs for the 10-Gigabit Ethernet MIC, see Component LEDs on the MX5, MX10, MX40, and MX80 Front Panel.

Each hot-removable and hot-insertable MIC has LEDs located on the faceplate. For more information about LEDs on the MIC faceplate, see the “LEDs” section for each MIC in the MX Series Interface Module Reference.

On the fixed MX80 chassis, each of the 48 ports on the fixed Tri-Rate MIC has a link LED. Table 8 describes the link LEDs in more detail.
