Troubleshooting
WARNING: Some Generator Set service procedures present hazards that can result in
severe personal injury or death. Only trained and experienced service
personnel with knowledge of fuels, electricity, and machinery hazards should
perform Generator Set service.
Possible Causes: Bad connections or bad communications
Corrective Actions:
1. Check connections.
a. Verify that the Ethernet cable is plugged into the generator set control and the router.
b. Verify that the computer is connected to the same router as the generator set via an
Ethernet cable.
c. Verify that the wireless card on the computer is turned off.
d. Check to see if both ends of the Ethernet cable are assembled and crimped as
described in the installation instructions. If not, reassemble and crimp as described in
the installation instructions.
e. Verify that the Ethernet cable connections between the generator set and the router
are solid and correct.
f. Proceed to "Check communications."
2. Check communications.
a. Check to see if you can access a standard web page with the computer connected to
the same router as the generator set. If not, contact your router manufacturer for
troubleshooting information.
b. Check to see if the green and orange lights are illuminated at the Ethernet connection
port on the generator set control board. If not, disconnect the Ethernet cable from the
generator control board and connect it to the computer. Check to see if you can
access a standard web page with the computer connected to the generator side of the
Ethernet cable.
a. If you can access a standard web page, call Cummins Support at
1-800-888-6626 and select option 1.
b. If you cannot access a standard web page, go to “Check connections" above.
c. Check to see if the correct generator IP Address has been entered, as described in
the Network Setup Guide. If not, enter the correct IP Address.
d. Check to see if you can access the generator set via the in-home network. If not, call
Cummins Support at 1-800-888-6626 and select option 1.
