the MPCs encapsulate the packets received. Each MPC is equipped with up to four Junos
Trio chipsets, which perform control functions tailored to the MPC's media type. The
MPCs interface with the power supplies and Switch Control Boards (SCBs). You must
install redundant SCBs to support full line rate.
The MX960 router supports up to 12 MPCs. You must install a high-capacity fan tray to
use an MPC. For power requirements, see
Routers" on page 161.
The router has 11 dedicated line-card slots for DPCs, MPCs, or FPCs. MPCs install vertically
in the front of the router. The dedicated slots are numbered
left to right. An additional multifunction slot labeled
an FPC, or an MPC. An MPC can be installed in any slot that supports MPCs. You can
install any combination of MPC types in the router.
When a slot is not occupied by an MPC or other line card, you must insert a blank DPC
panel to fill the empty slot and ensure proper cooling of the system.
MPCs are hot-removable and hot-insertable. When you install an MPC in an operating
router, the Routing Engine downloads the MPC software, the MPC runs its diagnostics,
and the Packet Forwarding Engines housed on the MPC are enabled. Forwarding on other
MPCs continues uninterrupted during this process.
Figure 31 on page 90 shows a typical MPC supported on the MX960 router.
Figure 32 on page 91 shows an MPC installed vertically in the MX960 router. For more
information about MPCs, see the MX Series Ethernet Services Routers Line Card Guide.
