Understanding Indicators
Before setting up your USB/Ethernet Cable Modem for the first time, take a few minutes to look over this section
and familiarize yourself with the front panel LED indicators depicted below.
♦ Power This LED is lit red when the device is receiving power; otherwise, it is unlit.
♦ Link This LED is lit green to indicate that a valid connection exists between the Ethernet port on the Cable
Modem and your PC. If it is unlit, there is no valid connection.
♦ Act A blinking green LED indicates that traffic activity is passing through your cable modem port.
♦ Status This LED is lit green when either the USB or Ethernet cable is successfully connected to your PC
and a traditional coaxial cable is connected to your Cable Modem tuner. This indicates a successful
connection with CMTS. The LED will now start quickly blinking as the DCM-200 attempts to lock a
downstream frequency. If this is successful, the LED will begin to blink slowly. This indicates the modem is
waiting for authentication, setting up an upstream connection, requesting an IP through DHCP, and then
requesting a configuration file through TFTP to establish contact, in that order. When the blinking stops
and the LED remains steady, the Cable Modem is ready to transmit data through the CATV network.
NOTE: If a powered-up device is connected to a port and the port’s Link status indicator is unlit, the most
probable cause is a cabling or connection problem (for example, the wrong cable type or a bad contact)
or a device malfunction. .
Powering Up the First Time
You must allow at least 1 to 3 minutes to power up the first time because the DCM-200 must find and secure a
connection.
