Back Panel Description 
The following  illustration identifies the back panel components on the DPC3828 and 
EPC3828 residential gateways. Descriptions for each component follow the 
illustration. 
 
Important: Do not connect  your PC to both the Ethernet  and USB ports at the same 
time. Your residential gateway will not function properly if both the Ethernet and 
USB ports are connected  to your PC at the same time. 
 
1  ON/OFF  SWITCH  (Provided only on products that carry the CE mark)—
Allows you to turn off the residential gateway without removing  the power cord. 
Turning the residential gateway off using this switch ensures that the unit is 
consuming no energy. 
2  POWER—Connects  the residential  gateway to the AC power adapter that is 
provided with your residential gateway. 
Important: Use only the power supply provided with your residential  gateway. 
3  USB (Optional for some models)—Connects  to selected devices. For models that 
support USB, the default is one USB port. 
4  ETHERNET—Four RJ-45 Ethernet  ports connect  to the Ethernet  port on your PC 
or your home network. 
5  CABLE—F-connector  connects to an active cable signal from your service 
provider. 
6  RESET—A momentary pressing (1-2 seconds) of this switch restarts (power 
cycles) the device. Pressing and holding  the switch for more than ten seconds 
first causes a reset-to-factory-default of all settings and then restarts (power 
cycles) the device.
