Using the Cable Modem

Buttons

ON/OFF – Turns the modem on or puts it in standby mode. Placing the cable modem in
standby mode (the "off" position) allows for continued status monitoring from the
cable network. This also disconnects your computer from the Internet for added security.
Important: Do not press this button when transmitting data over the internet. The
information will be lost and your Internet connection disabled.
LED/Light Indicators – Operational
Mode
POWER – Indicates whether the cable modem is in active or
standby mode. The light is off when the modem is in standby
mode, and on when the power is activated and in the operational
mode.
PC LINK – Indicates whether the connection between the computer
and the modem is active (ready to transmit/receive) or actually
transmitting/receiving. The light is off when no carrier is present (or
the modem is in standby mode), on when the carrier is present but
there's no transmit/receive activity, and flashing when there is
transmit/receive activity.
CABLE – Indicates the status of your cable connection. The light is
off when no cable connection is detected or the modem is in
standby mode and fully lit when the modem is registered with the
network and data can be sent.
ACTIVITY – Indicates the existence of data traffic in the cable lines.
The light is off when no data traffic is present and flashing when
data activity exists.
EMAIL– This light flashes when you have mail (if available through
service provider).
Note: If all of the lights are flashing sequentially, it means the cable modem is automatically
updating its system software. Please wait for the lights to stop flashing. You cannot use your
modem during this time. Do not remove the power supply or reset the cable modem during
this process.
