7.2.1.2 Replacing a CXCI+ Controller
1. Write down the CXC communication information: dynamic or static IP, IP address, and gateway.
2. Connect a laptop to CXC per software manual; standard network crossover cable to Ethernet port.
3. Save the CXC configuration file (see software manual Logs and Files > Manage Configuration File > Save
Full Site Configuration).
4. Save the CXC text file if necessary: Logs and Files > Manage Editable Text Files > Save Dynamic Text File.
5. If applicable, bypass the system LVD:
•
Locate JP2 on the back of CXCI/CXCI+ system shelf (Figure 11)
•
If the LVD is controlled on NC contacts (factory default for LVD option), then JP2 pins 1 and 2 must
be shorted together to maintain LVD operation.
•
If the LVD is controlled on NO contacts, then JP2 pins 2 and 3 must be shorted together.
NOTE
: bypassing the LVD generates an alarm.
6. Disconnect the DB signal connector from the CXCI+ at the rear of the shelf.
7. Ensure a converter is in the right-most position. Remove the converter in the left-most position in order to
access the side of the CXCI/CXCI+ where the mounting screws are located.
8. Place the CXCI+ controller module on the shelf bottom and slide into the rear connector at the back of the
slot.

9. Replace the DB connector on the back of the CXCI/CXCI+.
10. Log on to the CXC and go to
Logs and Files > Manage Configuration File > Upload Site Configuration
and select the saved *.cfg file. After the upload do a Submit Changes. Make sure the site information is
checked to save it, and click
Accept
.
11. Go to
Logs and Files > Manage Editable Text Files > Upload Dynamic Text File
and select the saved *.tfg
file. You do not need to submit changes; it is already saved.
12. Use a meter to verify the bus voltage and current shunt. Recalibrate as required due to differences in the new
CXCI/CXCI+.
13. Replace converters and remove LVD bypass.
