Routing Modules
Juniper MX router modules come in three kinds: MICs, the interface cards that sit in a line card; switch control boards, which carry the Routing Engine and switch fabric in MX240, MX480 and MX960 routers; and power modules for the larger chassis. Juniper's multi-rate Ethernet MIC for the MX10003, the JNP-MIC1, for example, fits the MPC10003 line card and has twelve QSFP28 ports that run as 100GbE, 40GbE or 4 x 10GbE, and a MACsec version exists too. Match each part to the chassis and line card Juniper lists for it; in-stock modules can go out the day you order. See also Optical Transceivers, Modules and Juniper Networks.

How MPCs, MICs and fixed MPCs fit an MX router
On MX routers with line-card slots, Juniper splits the job in two: the Modular Port Concentrator (MPC) does the packet forwarding and the Modular Interface Cards (MICs) inside it provide the ports, unless the MPC is a fixed-configuration card.
| Module | What it does (Juniper) | Where it goes |
|---|---|---|
| MPC | Packet forwarding, with up to four Junos Trio chipsets | A line-card slot: up to three in an MX240, six in an MX480, 12 in an MX960, 10 in an MX2008 or MX2010 and 20 in an MX2020; the MX10003 takes MPCs too |
| MIC | The physical ports, with framing and signaling for one media type; hot-insertable | Up to two per MPC, vertical on the MX960 and MX2000 routers and horizontal on the MX10003, MX480 and MX240; straight into the chassis on the MX5 to MX104 |
| Fixed-configuration MPC | Forwarding plus built-in ports or services | A line-card slot; it has no MIC slots |
| DPC, or FPC with PICs | Earlier line-card designs for the MX240, MX480 and MX960 | A line-card slot |
A MIC goes only into an MPC that supports it, which Juniper's MIC/MPC compatibility tables set out. Juniper also requires a high-capacity fan tray to run MPCs and a blank in every empty MPC slot.
