When the initial system boot is complete, verify the following:
•Power supplies are supplying power to the system. See the “Removing and Installing Power Supplies” section on page
•The system fan module is operating. See the “Removing and Installing the Fan Module” section on page
•The system software boots successfully. Refer to the Cisco MDS 9000 Family Configuration Guide for information on booting the system and initial configuration tasks.
•The supervisor module and the switching or services module are installed correctly and each one initialized without problems. For more information, see the “Removing and Installing Switching and Services Modules” section on page
If each of these conditions is met and the hardware installation is complete, refer to the Cisco MDS 9000 Family Configuration Guide to troubleshoot the software. However, if any of these conditions are not met, use the procedures in this appendix to isolate and, if possible, resolve the problem.
Solving Problems at the Component Level
The key to success when troubleshooting the system is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.
The Cisco MDS 9216 Switch includes the following subsystems:
•Power
•Fan
