This appendix describes how to identify and resolve problems that might occur with the hardware components of a Cisco Nexus 6000 Series switch.
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.
Use the recommendations in this section to ensure the proper installation, initialization, and operation of the switch.
This section includes the following topics:
When the initial system boot is complete, verify the following:
To ensure proper operation of your switch, take the following actions:
The two LEDs on each power supply indicate the power status for each power supply. To determine the current status for a power supply unit, note which LED is on, blinking, or off and refer to Table E-1 .
