, , and , bottom to top. An MPC can be installed in any slot on the router that supports
1/0 1 2
MPCs. You can install any combination of line card 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 26 on page 75 shows a typical MPC supported on the MX240 router.
Figure 5 on page 10 shows an MPC installed horizontally in the MX240 Router. For more
