CXCI Replacement Procedure
1. Write down the CXCI communication information: dynamic or static IP, IP address, and gateway.
2. Connect user laptop to CXCI per software manual; standard network crossover cable to Ethernet port.
3. A step-by-step connection (wizard) application – provided to establish remote communications with your CXC
– is available via the Alpha website (
www.alpha.ca
). The CXC Connection Wizard will save your LAN
configuration and restore it back when exiting the application.
4. Save CXCI configuration file (see software manual).
5. Remove signal wires (via DB connectors) from CXCI.
6. Ensure converter is in the right-most position.
7. Remove converter in the left-most position in order to access the side of the CXCI where the mounting screws
are located.
For latest CXCI design, regarding illustrations and procedure, refer to the Installation chapter.
Original CXCI design is shown below.
8. Remove four (4) mounting screws from the CXCI as shown below. The first two screws will release the front
panel from the controller circuit board to expose the third screw that releases the LCD. Carefully remove the
LCD to expose the fourth and final screw to release the remains of the CXCI.
