Getting Started
When the initial system startup is complete, verify the following:
• Power supplies are supplying power to the system.
• The fan tray assembly is operating.
• System software boots successfully.
If one or more of the above conditions are not met, use the procedures described in this chapter to isolate and,
if possible, resolve the problem. If all of the above conditions are met, and the hardware installation is complete,
refer to your software release notes for hardware support information and software caveats.
Solving Problems at the System 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 switch consists of these subsystems:
• Power supplies
• Fan tray assembly
