Step 4 Press Ctrl-Zto exit configuration mode.

Router(config)# Ctrl-Z

Step 5 Save your configuration changes:

Router# copy running-config startup-config

Resetting the Configuration Register Value

Follow these steps once you have recovered or reconfigured a password:

Step 1 Enter the configure terminal command to enter configuration mode:

Router# configure terminal

Step 2 Enter the config-registercommand and the original configuration register value that you recorded in Step 5.

Step 3 Press Ctrl-Zto exit configuration mode:

Router(config)# Ctrl-Z

Step 4 Reboot the router, and enter the recovered password.

Problem Solving

The key to problem solving is to isolate the problem to a specific subsystem by comparing what the router is doing to what it should be doing.

When problem solving, consider the following subsystems of the router:

WICs and VICs—Refer to the LEDs on the cards and the LEDs on the router front panel to help identify a failure. For more information on WICs and VICs, refer to the Cisco WAN Interface Cards Hardware Installation Guide that comes with each card.

Cables—Check all the external cables that connect the router to the network.

Power system—Check the external power source, power cable, router power supply, and circuit breaker. Check for inadequate ventilation or air circulation that might cause overheating.
