Troubleshooting the Route Processor Subsystem

The router processor subsystem consists of the route processor located on the RP card. The RP and the line
card each has the same onboard CPU serving as the main processor. The Controller Area Network (CAN)
microcontroller processor monitors the environment and controls the onboard DC-to-DC converters.

Route Processor Overview

The CPU on the RP card provides chassis control and management, boot media functionality, telecom timing
and precision clock synchronization, communication to the line card through the backplane Ethernet network,
and power control through the CAN bus. In addition, the CPU on the RP card also runs the routing protocols.
The following figure identifies the slots, ports, and LEDs on the RP card front panel.
