Step 5: Install the GCTU2 (Processor)
The GCTU2 is the main processor for the CIX40. It is shipped in a separate box, not in the CIX40
cabinet. The GCTU2A is considered a unit, separate from the cabinet for repair, return and
warranty purposes.

To install the GCTU2 into the CIX40
1. Skip this step if you have installed a Voice Mail PCB and already removed the PCB stopper. If
you have not done this, then in the CIX40 cabinet, remove the two screws and the PCB
stopper (see Figure 1-17).
2. Set the P601 battery jumper to ON (see Figure 1-18) and insert the GCTU2 in the upper slot of
the GMAS sub-motherboard (see Figure 1-12). Place it next to the guide rail of the PCB
stopper (see Figure 1-17).
3. Secure the PCB stopper with the original two screws.
4. Insert the SecureDigital card (gold contacts to left and front, notched corner faces forward and
down) into the SecureDigital slot on the GCTU2 (see Figure 1-18).
