3 MNG-2000 Cable Modem Front
The front of the MNG-2000 cable modem include five LED's that are marked POWER, STATUS, UP,
DOWN and LAN. These are used in indicating the operating status of the cable modem.
3.1
LED
POWER
When the DC adaptor plug is connected and power applied to the MNG-2000 cable modem, all
five LED's will light up briefly before the POWER LED lights up. This indicates that power has
been correctly applied to the modem.
While the POWER LED lights up, the cable modem copies its operating program from the flash
memory to the dram memory. The LED will remain constantly on as long as power is applied.
3.2
STATUS LED
The STATUS led remains flashing while the modem is being initialized. After initialization is complete
and normal operation is possible, the STATUS LED remains green. The STATUS LED needs to
remain green in order for the Internet access to work properly.
After power is applied to the cable modem and its operating program is copied to DRAM, the modem
searches for the downstream channel.
3.3 UP LED
After the MNG-2000 cable modem as found the downstream channel, the DOWN LED will turn
green. During the time that data traffic is flowing through this downstream channel, the DOWN will
begin flashing.
3.4 DOWN LED
The MNG-2000 cable modem acquires upstream channel information from the downstream channel
and performs ranging in order to transmit data on the upstream channel properly. The UP LED will turn green
following completion of ranging and the modem is now ready transmit data. When transmit is in progress, the
UP LED will flash. If the upstream channel is lost, the UP LED will turn off.
