Understanding the Power Amplifier module
The Power Amplifier (PA) is one of two modules that make up the Sector Radio Kit. See Figure 8
and Table
10. PAs install in upper slots 1, 5, and 9, depending on the radio sector. The PA supports a single sector and
a single corresponding antenna. Typical deployments support three sectors and use three PAs.
The PA is field-replaceable and hot swappable. Replacing an active PA in the field is service disrupting for
its sector.
For information about installing the PA module:
• See Understanding the installation process
on page 40.
• See Understanding the module installation process
on page 104.
