Connecting cable components

You should allow 5 to 30 minutes to power up the first time because the modem must find and lock on the appropriate channels for communications. This procedure is the same no matter which cable modem you have.


  1. Cable Wall Outlet— this is your cable service outlet
  2. Coaxial Cable— this is the cable that connects your modem to the cable wall outlet in your home.
  3. Electrical Socket
  4. Power Supply — connects the power from the modem to the electrical socket
  5. Your Computer (or router)
  6. Ethernet Port - connection port on the back of your modem to plug an Ethernet cable into from your computer or your router

Due to regional power outages, Northwestel suggests using a power bar or UPS when plugging in the modem to prevent or minimize any damage to the unit or disruption in service.

  1. Turn your computer on and make sure your cable modem is unplugged.
  2. Connect one end of the coaxial cable to the cable outlet or splitter. Connect the other end to the cable connector on the back of your modem.
  3. Hand-tighten each connector to avoid damage.
  4. Plug the power cord adapter end into the +12VDC connector on the cable modem and the plug into the electrical outlet. This will turn the modem on. You do not need to unplug it when not in use.
  5. Check that the lights on the cable modem or wireless gateway front cycle through this sequence:
  • Receive flashes while scanning for the download channel and changes to solid green on the 5100 series and Cisco DPC3825 and solid blue on the 6120 and 6121 when it is connected
  • Send flashes while scanning for the upload channel and changes to solid green when it is connected.
  • Online flashes while the cable modem downloads configuration data and changes to solid green when the download is complete.
  1. Now you can reconnect your computer or router to the modem via the Ethernet port using the supplied Ethernet cable.
  2. Note: If both the Power & Receive lights are flashing then the modem has been disabled. Please call Northwestel Support at 1 888 423-2333.
