Troubleshooting the Processor Subsystem
The router processor subsystem consists of the route processor, line cards, and
alarm cards. The RP and the 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.
Note
A minimally configured router must have an RP installed in slot 9 of the card cage
to operate. If the router is equipped with a redundant RP, the redundant RP must
be installed in slot 8 of the card cage.
