Table 2: Hardware Connections
WPS Press this button to begin the WiFi Protected Setup
(WPS) Push-Button Configuration (PBC) procedure.
Press the PBC button on your wireless clients in the
coverage area within two minutes to enable them to join
the wireless network.
See WPS on page 63 for more information.
USB The CGNV4 provides a USB 2.0 host port, allowing you
to plug in USB flash disks for mounting and sharing
through the LAN interfaces via the Samba protocol
(network neighborhood).
The CGNV4 supports the following Windows file
systems:
 FAT16
 FAT32
 NTFS
USB devices must not drain more than 500mA
from the USB port. USB devices requiring
more than 500mA should be provided with
their own power source(s).
LINE 1 Use these ports to connect your analog phones for VoIP
services, using cables with RJ11 connectors.
LINE 2
RESET Use this button to reboot or reset your CGNV4 to its
factory default settings.
To reboot the CGNV4, press the button and hold it for
less than five seconds. The CGNV4 restarts, using your
existing settings.
To reset the CGNV4, press the button and hold it for
more than ten seconds. All user-configured settings are
deleted, and the CGNV4 restarts using its factory default
settings.
LAN1 Use these ports to connect your computers and other
network devices, using Category 5 or 6 Ethernet cables
with RJ45 connectors.

1.3 LEDs
This section describes the CGNV4’s LEDs (lights).
CABLE Use this to connect to the Internet via an F-type RF
cable.
POWER Use the POWER port to connect to the 12v/2A power
adapter that came with your CGNV4. Use the POWER
switch to turn the CGNV4 on or off.
NEVER use another power adapter with your
CGNV4. Doing so could harm your CGNV4.
