Field Replaceable Parts and Modules

The MCPAs, rectifier modules, Control Module, Modem, RF conditioning unit, door fan assemblies, and power

system fuses can be replaced in the field on site by a qualified technician with experience maintaining RF

power amplifiers and similar equipment.

Opening the front or rear doors, or both as appropriate, is required to perform the following maintenance

operations. Door latches are 1/4 turn and require a 10 mm hex socket wrench or nut driver to open.

Table 4-3 lists the model numbers and descriptions for ordering individual field replaceable system

components.
