Inspecting the system
If the system you are servicing does not meet a condition, and it is not obvious what action(s) you should take to fix the
problem (for example, if the system hangs before reaching Idle), identify the symptom and perform the suggested action(s)
for the condition.
Important:
Before you remove the E-45 panels, be aware of the safety precautions that you should take when
handling the E-45. Use standard ESD precautions when handling printed circuit boards and electronic components.

Important:
If your initial checks of the cable and board connections do not fix the problem, you may need to inspect
the system on a component-by-component basis, as described in
comprehensive inspection allows you to verify that each hardware component is properly installed and configured,
and helps you avoid replacing expensive components unnecessarily.
