10 Communication Troubleshooting
10.1 In-Home Network Access to Generator Set
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 that is attempting to access the generator set is connected to
the same router as the generator set via an Ethernet cable (on the same local area
network).
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. If the router is also connected to an incoming connection from an ISP, 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 the lights are not illuminated, this indicates
that no information is being transmitted or received. Test the cable by disconnecting
the Ethernet cable from the generator control board and connecting it to the computer
(swap the cable with the exisiting Ethernet cable). With the router connected to the
ISP, check to see if you can access a standard web page.
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 the “Check connections" step
above.
c. Check to see if the correct generator IP address has been entered. If not, enter the
correct IP address in the address bar of the web browser. Be sure to not enter "www"
or other text prior to the IP address.
