The Synchronous Interface Module (SIF) is installed into Slot 7 or Slot 8 of the RAN chassis. One SIF module is required for each two bands installed in the RAN. For the first two bands use Slot 7. For the second two bands, use Slot 8.
Note: For a description of the SIF module, including function, controls, and indicators, refer to Section 1.7.4 on Page 15. For a RAN chassis interconnection diagram, refer to Figure 40 on Page 58.
Use the following procedure to install the SIF module (Figure 44):
1.Open the RAN door.
2.Locate the designated slot for the SIF module. The module installs into Slot 7 or Slot 8. Refer to the introductory text above for more information.
3.Remove the SIF from the
4.Slide the SIF into the designated slot within the RAN chassis.
5.Lock the IEL handles on the top and bottom of the SIF module into the cPCI chassis and tighten handle screws.

6.If this SIF module is being installed into Slot 7, connect the short CAT5e jumper (cable 1001478P001) between the “10BT” port on the SIF and the “ENET” port on the CPU module. (For a slot 8 SIF, no cable is required.)
7.Carefully route the internal fibers to the front of the SIF module.
