4.1.1 Installing a Central Processing Unit (CPU) Module
The Central Processing Unit (CPU) module installs into Slot 5 of the RAN chassis. Only one
CPU may be installed in the RAN chassis.
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 anti-static packaging and orient the module for
installation as shown in the figure.
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: 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.
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).
