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 |
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 existence of data traffic in the cable lines. The
light is off when no data traffic is present and
flashing when data activity exists. |
| Status |
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. |

Power
= Tuning - The cable modem
is functional and searching for a down stream cable
modem service channel on the system.
|
| Power
& PC Link = Ranging - The
modem is now tuned to a downstream cable modem channel
and can now receive data. Now it searches for an
upstream channel so that it can send data. |
| Power
& PC Link & Cable = Connecting - The
cable modem is now communicating start-up data both
downstream and upstream. The System is
establishing IP connectivity with your modem. |
| Power
& PC Link & Cable & Status = Configuring -
The cable modem received
its IP Address and is downloading its configuration
file from the system. |
| Power
& PC link & Cable & Status = Registering -
The cable modem
configuration is complete. It is registering its
"as configured" settings with the system.
Once complete, the lights stop flashing and the modem
enters Operational Mode. |

Reset
Switch
The reset switch can be found behind a “toothpick
hole” on the back panel. It performs two functions:
1. Basic Reset – Press and release the switch to
make it perform the same function as disconnecting the
power from the modem. It will start up again in
Initialization Mode.
2. Factory Default Reset – Unplug the modem from the
AC power. Press and hold the reset switch while
plugging the modem into AC power. Continue holding the
switch. Release the switch when all lights come on
(about 6 seconds). This will return the modem to a
factory “out of box” condition. This should only
be done if the cable modem has been taken out of
service in one location and is being reconnected to a
different service, or if instructed to do so by
system.
