MPC Components

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 33 on page 69 shows a typical MPC supported on the MX2020 router.
Figure 34 on page 69 shows an MPC installed vertically in the MX2020 router. For more
information about MPCs, see the

Each MPC consists of the following components:
MIC card carrier, which includes two MIC slots (excludes the fixed configuration MPC).
Fabric interfaces.
Two Gigabit Ethernet interfaces that allow control information, route information, and
statistics to be sent between the routing engine and the CPU on the MPCs.
