Troubleshooting Hardware Components
This appendix describes how to identify and resolve problems that might occur with the hardware components of a Cisco Nexus 6000 Series switch.
This appendix includes the following sections:
•Overview, page
•Switch Hardware Best Practices, page
•Power Supply Conditions, page
Overview
The key to success when troubleshooting the system hardware 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.
Problems with the initial power up are often caused by a module that is not firmly connected to the backplane or a power supply that has been disconnected from the power cord connector.
Overheating can also cause problems with the system, though typically only after the system has been operating for an extended period of time. The most common cause of overheating is the failure of a fan module.
