The RP is used as the main system processor for the Cisco 12404 Internet router
Slot number 0 (zero) is the recommended slot for the first RP card.
The RP communicates with the line cards either through the CSF or the through
the maintenance bus (MBus). The CSF connection is the main data path for
routing table distribution as well as for packets that are sent between the line cards
and the RP.
The MBus connection allows the RP to download a system bootstrap image,
collect or load diagnostic information, and perform general internal system
maintenance operations. The RP can be installed in any of the five slots in the card
cage in the Cisco 12404 router, but slot number 0 (zero) is the recommended slot
for the first RP.
