Troubleshooting

The Telephony modem is plugged in, but the Power light is off.
Check all power connections. Is the power cord plugged in firmly at both
ends?
Model TM902S only: Is the rear panel power switch in the ON position?
If you plugged the power cord into a power strip, make sure the strip is
switched on.
Avoid using an outlet controlled by a wall switch, if possible.
Check the outlet by plugging in another device (such as a lamp).
Finally, check the fuse or circuit breaker panel.
I'm not getting on the Internet.
It may take over 30 minutes to establish a connection the first time you
power up your Telephony Modem, especially when many people are online.
Always leave your Telephony Modem plugged into AC power and connected
to the cable system.
Check the front panel lights:
• The Power and Online lights should be on.
• The Link light should be either on or blinking.
• If the Power light blinks for more than 30 minutes, call your cable com-
pany for assistance.
Check your cable connections. Connectors should be tight. The
should not be pinched, kinked, or bent sharply—any of these can cause a
break or short in the cable (you may have to replace the cable). If you have
one or more splitters between the Telephony Modem and CATV outlet, re-
move the splitters and connect the Telephony Modem directly to the outlet.
Proceed to the Ethernet solution (next page) if necessary.
