14.2 Mechanical Overview
The TB8100 PMU is made up of a number of individual boards and cards
which comprise two main modules, the AC module and the DC module.
The auxiliary power supply board is optional.
The PMU is available in three main hardware configurations:
■ AC PMU (AC input only)
■ DC PMU (DC input only)
■ AC and DC PMU (both the AC and DC modules are fitted to allow both
AC and DC inputs).
The table below provides an overview of the major mechanical differences
between these three configurations.
Figure 16.1 on page 269 and Figure 16.2 on page 270 identify the main
mechanical parts. Figure 13.1 on page 218 identifies the individual boards
and cards, and shows how they are configured in an AC and DC PMU.
“Identifying the PMU” on page 217 explains how to identify the model and
hardware configuration of a PMU from its product code.
Note For the sake of simplicity and clarity, the instructions and illustra-
tions in this chapter refer to the AC and DC PMU. However, the
AC PMU and DC PMU can be disassembled and reassembled
using the same basic procedures and techniques.
