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.

MCPA Removal and Replacement
Perform the instructions in Table 4-4 to remove and replace the MCPA shown in Figure 4-1 MCPA Removal
and Replacement.
CAUTION: When removing the MCPA from the subrack, support the rear of the MCPA to prevent a sud-
den drop when the guide rail disengages from the track. This could damage the rear multi-pin connector.
The MCPA weights approximately 20 lbs. (9.1 kg).
If an MCPA module is removed, another MCPA or blank panel must be installed in its place to provide ade-
quate cooling.
Always disable the MCPA of a sector prior to the removal of a MCPA or RFCU of that sector.
Table 4-4 MCPA Removal and Replacement Procedures
Step Action
1Set OFF/ON/RESET switch on front panel of MCPA down to OFF.
2 Rotate latches securing MCPA to subrack counterclockwise.
3With steady even pressure, use handle on front of MCPA to slide MCPA out of subrack.
4 Replace MCPA by carefully sliding MCPA into empty subrack slot. Secure MCPA by turning two latches
clockwise.

Rectifier Module Removal and Replacement
Perform the instructions in Table 4-5 to remove and replace the rectifier module shown in Figure 4-2
CAUTION: The rectifier module weighs approximately 5 lbs. (2.3 kg). When removing the rectifier module from
the subrack, support it at the rear when the guide rail disengages from the track to avoid dropping the module.
Dropping the rectifier module could damage the rear multi-pin connector.
Table 4-5 Controller Module Removal and Replacement Procedures
Step Action
1Using a #2 Phillips screwdriver, loosen the Phillips fastener securing the latch.
2 Slide and hold latch to left
3Use handle to carefully pull rectifier module out of cabinet
4 Replace rectifier by carefully sliding rectifier into empty slot until rectifier is secured

RF Conditioning Unit (RFCU) Removal and Replacement
Perform the steps listed in Table 4-7 to remove and replace the RF conditioning unit shown in Figure 4-4. The
RFCU unit contains unique calibration tables. The OS system will upload the tables to the Controller
automatically upon insertion.
CAUTION: The RFCU weighs approximately 40 lbs. (18.14 kg). When removing the RFCU Module from the
subrack, support it at the rear when the guide rail disengages from the track to avoid dropping the module.
Dropping the RFCU Module could damage the rear multi-pin connector.
Always disable the MCPA of a sector prior to the removal of a MCPA or RFCU of that sector.
Table 4-7 RF Conditioning Unit (RFCU) Removal and Replacement
Step Action
1Disable the MCPAs in the affected sectors.
2Disconnect external cables to RFCU interface in the affected sectors.
3 Using a slotted screwdriver with a 8mm (5/16 in) typical blade, loosen the top and bottom fasteners
securing the RFCU to the OS system.
4With steady pressure, use the handle on the front of the RFCU to slide the unit out of the OS system.
5 Replace RFCU in reverse order

Fan Assembly Removal and Replacement
Perform the instructions in Table 4-8 to remove and replace the fan assembly shown in Figure 4-5.
CAUTION: Ensure the fan assembly is replaced by the correct type. Front fans and rear fans are assem-
bled different per air flow.
