Troubleshooting
If your eMTA does not operate properly, the following should be verified first. If going through
this list still results in inoperability, contact your cable service provider.
Verify that the plug to the eMTA is securely plugged in.
Verify that the AC adapter is not plugged into an electrical outlet that is controlled by
a wall switch. If it is, then make sure that the switch is turned on.
Verify that the
POWER
and
ONLINE
LED lights on the front panel of the eMTA are
illuminated.
Verify that the cables are properly connected with the correct cables.
Verify that you have an active cable service which supports two-way service.
Verify that you have provided your cable service provider with your eMTA’s serial
number and MAC address.
If you are using a cable splitter to connect the eMTA to other devices, remove the
splitter and reconnect the cable of the eMTA directly to the cable input. If this works,
then the cable splitter may need to be replaced.
Internet Service

Verify that your computer has a
10/100 BaseT Ethernet card and the Ethernet driver software is properly installed.
Telephone Service

service.

needed.
