3. Setup
Follow these steps to set up your Akuvox SP-R50P IP Phone for first-time use.
- Attach the Phone Stand: Align the tabs on the phone stand with the slots on the back of the phone base unit. Slide the stand into place until it clicks securely.
- Connect the Handset: Plug one end of the coiled handset cable into the handset jack on the side of the phone base unit and the other end into the handset.
- Connect to Network and Power:
- Using PoE (Power over Ethernet): If your network switch supports PoE, connect an Ethernet cable from the LAN port on the back of the phone to a PoE-enabled port on your network switch. The phone will power on automatically.
- Using a Power Adapter (Optional, not included): If PoE is not available, connect a compatible 5V DC power adapter (not included) to the power jack on the back of the phone, then plug the adapter into a power outlet. Connect an Ethernet cable from the LAN port on the back of the phone to your network router or switch.
- Initial Boot-up: The phone will power on and begin its boot-up sequence. The LCD screen will display the Akuvox logo and then proceed to load the operating system. This may take a few moments.
- Network Configuration: Once booted, the phone will attempt to obtain an IP address via DHCP. If your network requires static IP configuration or specific SIP server settings, these can be configured via the phone's web interface or directly on the phone's menu (refer to Section 4.2 for menu navigation).
