Troubleshooting
During power up, your Cisco Catalyst 6500 Series switch or Cisco 7600 Series Internet Router goes
through a system check. This system check also includes all the modules (for example, the MWAM) that
are installed.
If your MWAM is not powering up properly, begin troubleshooting using the procedures in this
appendix. This appendix guides you through some initial checks and procedures that can solve some
basic MWAM problems. It can also direct you to the appropriate d

Appendix B Troubleshooting General Problem Solving General Problem Solving As you start your problem solving, you first look at the way your Catalyst 6500 switch or Cisco 7600 router is responding during power up. The key to problem solving is to isolate the problem to a specific subsystem by comparing what your switch or router is doing to what it should be doing. The LEDs on the front panel of the switch or router enable you to determine the switch or router performance and operati
