Hardware maintenance principles apply to all the panels. All the panels have passed hardware tests
before leaving the factory, and any hardware problem found later may be mainly caused by power
problems. Thus, hardware maintenance primarily involves the power supply. Hardware problems
and maintenance methods for each panel are described in the subsequent sections.
