The Central Processing Unit (CPU) module installs into Slot 5 of the RAN chassis. Only one CPU may be installed in the RAN chassis.
Note: For a description of the CPU module including function, controls, and indicators, refer to Section 1.7.2 on Page 13. For a RAN chassis interconnection diagram, refer to Figure 40 on Page 58.
Use the following procedure to install the CPU module (Figure 42):
1.Open the RAN door.
2.Locate the designated slot for the CPU module. The CPU module installs into Slot 5, which is identified with a red colored card guide.
3.Remove the CPU module from the
4.Slide the CPU module into the designated slot within the RAN chassis.
5.Lock the IEL handles on the top and bottom of the CPU module into the cPCI chassis.
6.Tighten the two Phillips head screws inside the handles.
7.Connect the short CAT5e jumper (cable 1001478P001) between the “ENET” port on the CPU module the “10BT” port on the SIF module.
Note: If there are two SIF modules present, connect the cable to the first SIF module (leftmost SIF module when viewed from the front of the chassis).
