Component Failure Description
3.1.1 Component Failure Detection
In this chapter, we will explain how the failure is spotted. The
following sections will provide the failure type definition and solutions
for the specific components.
The components here include the baseband board, RF module,
power module, antenna and feeder equipment, etc. If something
goes wrong with any of them, we can check the relevant alarm boxes,
maintenance console and the component indicators for information
about the component failure.
3.1.2 General Handling Procedure
When handling component failure, generally we should go “from
outside to inside”. The transmission link check and GPS receiving
signal check are external checks while the check on the boards and
modules are internal checks. The purpose of making such division is
to help us better understand the handling procedure. The external
check is actually combined with the internal check.
