How to Connect to the Wired Network

Follow the steps below to connect to the CMU Wired Network. Note: IT Staff or Student Organizations who maintain network registrations for their group should follow alternate Network Registration guidance.

Before you start, do either of the following apply to you? If so, proceed directly to Step 2: Connect the Ethernet Cable.

  • You are connecting to the wired network in a registrar classroom. Outlets in Registrar Classrooms are already active.
  • You have a CMU phone with an unused ethernet cable attached. You can connect your computer to your phone via this cable to take advantage of your phone's active outlet. Note: Do not unplug the ethernet cable that connects your phone to the outlet.

If neither applies, follow these steps to activate your outlet:

  1. Connect to the CMU network. If you are off campus, connect to VPN first before proceeding.
  2. Visit CANDO.
  3. Click Enter Cable and Network Distribution Operations Application (left).
  4. Log in with your Andrew userID and password, then authenticate with DUO when prompted. CANDO displays a list of your previous activations.
  5. On the sidebar, double-click CANDO Navigation >  Activations > New Activation
  6. Click New Activation (left). The New Activation tab displays.
  7. Select the LocationBuilding, and Room from the appropriate drop-downs.
    Note: CANDO displays a list of available outlets and their activation statuses. If the outlet you wish to activate is already active, proceed to Step 2: Connect the Ethernet Cable.
  8. Click the outlet you wish to activate and click Request Activation to submit your request. Note: Outlet activation may take up to two business days.

Note: This completes the student activation process.

Note: The following options may not be available for students.

  1. Your Configuration Details should autopopulate based on your location. Click Save to apply.
  2. To customize configuration details click the Network drop-down and select the name of your building.
  3. Click Template and select the appropriate option. If unsure of the template, select Single Host (User or Server).
  4. Click Save. A summary of your outlet activation will display.
  5. Click Expires On and set an expiration date for the activation, if desired.
  6. Click Save.

Once the outlet has been activated:

  1. Connect your ethernet to your computer.
    Note: If your computer doesn't have an ethernet port, you will need an adapter.
  2. Connect the other end of the ethernet cable to wall outlet.
