Before You Begin
Take the following precautions before installing the CH6640E/CG6640E:
Postpone installation until there is no risk of thunderstorm or lightning activity in the
area.
To avoid potential shock, always unplug the power cord from the wall outlet or other
power source before disconnecting it from the CH6640E/CG6640E rear panel.
To prevent overheating the CH6640E/CG6640E, do not block the ventilation holes on
the sides of the unit. Do not open the unit. Refer all service to your Internet Service
provider.
Check that you have the required cables, adapters, and adapter software. Verify that the
proper drivers are installed for the Ethernet adapter on each networked computer. For
