Troubleshooting the Processor Subsystem

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.
