4.4Installing a Compact PCI Power Supply (cPCI P/S) Module
The cPCI Power Supply Module installs into Slots 1 and 2 or Slots 3 and 4 of the RAN chassis. One module is required per RAN chassis. Either set of two slot can be used. A second module can be installed for redundancy.
Note: For a description of the cPCI P/S module including function, controls, and indicators, refer to Section 1.7.1 on Page 12. For a RAN chassis interconnection diagram, refer to Figure 40 on Page 58.
Use the following procedure to install a cPCI Power Supply Module:
1.Identify the designated chassis slots for the module. This will be Slots 1 or 2 or Slot 3 and 4.
2.Remove the module from the
3.Slide the module into the designated slots within the RAN cPCI chassis.
4.Lock the IEL handles on the top and bottom of the RUC module into the cPCI chassis and tighten handle screws.
4.5Installing a Power Amplifier Assembly
The RAN holds up to four PAAs. One PAA is required for each band being supported. Use the following procedure to install a PAA:
Note: For a description of the PAA including function, controls, and indicators, refer to Section 1.9 on Page 25. For a RAN chassis interconnection diagram, refer to Figure 40 on Page 58.
1.Connect cables per Table 23.
2.Slide the PAA into place.
