Troubleshooting the Processor Subsystem
Note
OL-11495-01
The router processor subsystem consists of the RPs, line cards, and alarm cards.
The RPs and line cards have two onboard processors; one serves as the main (or
master processor), and the other serves as the MBus module processor. The MBus
module processor monitors the environment and controls the onboard DC-to-DC
converters.
A minimally configured router must have an RP installed in slot 7 of the upper
card cage. If the router is equipped with an optional, redundant RP, that RP must
be installed in the far left slot in the lower card cage (slot 8).
