8. If the optical transceiver is mounted into the SIF module, then connect the fiber to the dual
LC connector. If optical transceiver is not mounted into the SIF module, follow the SFP
installation procedure in
4.1.4
Installing a Small Form-Factor Optical Transceiver (SFP)
The SFP installs in the front center of the SIF module.
Note: For a description of the SFP, refer to
description of the SIF module faceplate in
Use the following procedure to install an SFP:-
1. Locate the transceiver socket on the front of the SIF and remove the port cover from the
socket.
2. The color of the transceiver extractor handle corresponds to the optical specifications of
the SFP and CWDM designations. Select the optical transceiver that is to be used to
communicate with the target RAN.
Note: For CWDM systems, it is extremely important that the correct wavelength be
installed in each SIF. Consult the site fiber plan for details
3. Remove the transceiver from the anti-static packaging and orient for installation.
4. Insert the optical transceiver into the socket until it locks into place.
5. Connect fiber or replace the optical transceiver dust cap if it was removed for installation.
4.1.5
Installing a RAN Down Converter (RDC or RDC2) Module
The RAN Down Converter (RDC) module may be installed into any of four slots in the RAN
chassis, depending on the band for which the module will be used. One RDC module is required
for each band. The four slots are:
• Slot 10 (labeled RDC A1): used for first band
• Slot 12 (labeled RDC A3): used for second band
• Slot 13 (labeled RDC A4): used for third band
• Slot 15 (labeled RDC A6): used for fourth band
Note: For a description of the module including function, controls, and indicators, refer to
Section 1.7.6 on Page

58.
Use the following procedure to install an RDC or RDC2 module
1. Identify the slot designated RAN chassis slot for the RDC module. This will be Slot 10,
12, 13, or 15. For more information, refer to the introductory text above.
2. Remove the RDC module from the anti-static packaging and orient the module for
installation.
