Setup
1. Connecting the Phone
Before connecting, ensure your network infrastructure is ready for VoIP devices.
- Attach the Phone Stand: Align the stand with the slots on the back of the phone and snap it into place.
- 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.
- Connect to Network:
- Ethernet (PoE): If using Power over Ethernet, connect one end of the Ethernet cable to the LAN port on the phone and the other end to a PoE-enabled switch or injector. The phone will power on automatically.
- Ethernet (Non-PoE): If not using PoE, connect one end of the Ethernet cable to the LAN port on the phone and the other end to your network switch/router. Then, connect the 5V power adapter to the phone's power port and a power outlet.
- Wi-Fi: For Wi-Fi connectivity, the phone must first be powered on (via PoE or power adapter) and connected to the network via Ethernet for initial configuration, or configured directly on the phone's interface after boot-up.
2. Initial Boot-up
Once connected to power and network, the phone will begin its boot-up sequence. This may take a few minutes. The display will show the Grandstream logo, followed by network status and SIP account registration status.
