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.
