Before you begin, ensure all components are present:

3.2 Connecting the Phone

  1. Connect the Handset: Plug one end of the coiled handset cord into the handset and the other end into the handset port on the phone base.
  2. Connect to Network: Connect one end of the Ethernet cable to the LAN port on the back of the phone and the other end to an active network port (e.g., a wall jack or network switch). If using Power over Ethernet (PoE), the phone will power on automatically.
  3. Connect Power (if not using PoE): If your network does not provide PoE, connect an optional Mitel-approved power adapter to the power port on the phone and then to a standard electrical outlet.
  4. Initial Boot-up: The phone will power on and begin its boot-up sequence. This may take a few moments as it obtains an IP address and registers with your communication system.
