    This section describes the troubleshooting methods used in this chapter and describes how the Cisco 7401ASR router is divided into subsystems for more efficient problem solving. If you are unable to easily solve the problem, contact a customer service representative for assistance and further instructions.

    System startup successful. — — In addition to following the subsystems approach to troubleshooting, Cisco Registered Direct users can access troubleshooting tools at http://www.cisco.com/kobayashi/support/tac/tools_az.shtml. Problem Solving Using a Subsystems Approach The key to solving problems with the system is isolating the problem to a specific subsystem. The first step in solving startup problems is to compare what the system is doing to what it should be doing.
