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. Each MPC is equipped with up to four Junos Trio chipsets, which perform
control functions tailored to the MPC's media type.
The MX2020 router supports up to 20 MPCs. For power requirements, see
DC Power Requirements for MX2020 Routers" on page 365
Requirements for MX2020 Routers" on page
The router has 20 dedicated line card slots for MPCs. MPCs install vertically in the front
of the router. The dedicated slots are numbered
(top), left to right. An MPC can be installed in any line card slot. The user can install any
combination of MPC types in the router.
When an MPC slot is not occupied by an MX2000 MPC or an ADC with MPC, a blank
MX2000 panel needs to be installed.
MPCs are hot-removable and hot-insertable. When the user installs an MPC in an
operating router, the CB-RE downloads the MPC software, the MPC runs its diagnostics,
and enables the Packet Forwarding Engines housed on the MPC. Forwarding on other
MPCs continues uninterrupted during this process.
Figure 10 on page 22 shows a typical MPC supported on the MX2020 router.
