2.6 Re-Assembling the UMBC
After replacing the SoM, complete the following steps to re-assemble the UMBC:
1. Verify that the power is turned off.
2. Gently rotate the PCB and place it into the enclosure.
3. While supporting the UMCB with one hand, attach the four mounting screws using
a 6.5 mm slotted screwdriver.
4. Connect the Ethernet cable.
5. Re-attach any additional cables connectors that were previously removed.
6. Using a 2.5 mm slotted screwdriver, tighten the two captive screws to attach the
UMCB’s power supply connectors.
Ensure that all connectors are re-attached in their original position and the
captive screws are tightened.
7. Using a 2.5 mm slotted screwdriver, tighten the two captive screws to attach the
touch screen’s connectors (if equipped).
8. Using a 5 mm hexagon key wrench, close the electronics enclosure and secure it
with the 10 M8 1.25 x 25 mm socket-head cap screw cover bolts.
2.7 Restoring the Database
Restoring the database requires an external Ethernet connection available in an area
that is safe to use a laptop computer. If this is not available, the UMCB board must be
removed the from enclosure and taken to a safe area where it can be powered on and
connected to a PC.
Complete the following steps to restore the backed-up database:
1. Power up the UMCB. Be sure to follow the precautions noted in section 1.5.1:
2. Connect to the meter using a web browser (Google Chrome is recommended) and
upload the parameter file from the previously created USC file.
When uploading this parameter file to the new SOM, the meter tag name will not
transfer; you will need to program this a the web browser after uploading the
parameters.
