Troubleshooting Tips
The Cisco DVB CAR100 can take up to 20 minutes to sign on the very first time and,in extreme circumstances,
even longer. In such instances, contact your cable service provider for advice.
If the power LED on the front of the Cisco DVB CAR100 does not turn green after the initialization procedure,
the modem is not functioning correctly.
If the Cisco DVB CAR100 is powered off, it should remain off for at least 10 minutes before being restarted. If
the unit is powered on within 10 minutes, it is possible that it will fail to reestablish communication with the
service provider's headend unit. If this occurs, power the unit off again, and leave it off for at least 10 minutes.
Then power on the Cisco DVB CAR100 again,and communication with the service provider's headend unit
should be reestablished as normal.
Safety
Ensure free air flow around the Cisco DVB CAR100 and power supply unit at all times to prevent
overheating.
