Getting Started
Start the Cisco Nexus 7000 Series switch by turning on the power at the power supply units to send power to the system fans, supervisor module, fabric modules, and I/O modules. During the startup phase, the STATUS LEDs on the supervisor and I/O modules are amber to indicate that the initialization process is in progress. When the system is operational, the component LEDs indicate that either the system is operational or you need to troubleshoot for system problems.
The key to troubleshooting the system is to isolate a problem to a specific system component. First, you compare what the system is doing with what it should be doing. Look at the chassis LEDs to see if there are any critical problems detected with the system components. Green chassis LEDs indicate that all components of a type are operational while amber LEDs indicate that at least one component of a type has a critical problem that requires troubleshooting.
For a listing of the system LEDs and the conditions that they indicate, see Table D-1 on page D-1 .
Less critical problems, such as minor overtemperature conditions, are not indicated by the chassis LEDs. To find those problems, you must look for amber STATUS LEDs on the system modules.
Depending on the type of component that needs troubleshooting, see one of the following topics:
