Getting Started
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.
