Troubleshooting the Route Processor Subsystem

•If the fan tray is still not operating, there could be a problem with either the fan tray or with the

+12 VDC distribution through backplane.

•Contact your Cisco representative if replacing the fan tray does not fix the problem.

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.

•Configuring and Troubleshooting Line Card Interfaces, page4-13

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.

Figure 4-2 identifies the slots, ports, and LEDs on the RP card front panel.
