- Connexió a PC (opcional): The phone includes an integrated Ethernet switch port. To connect your computer through the phone, connect an Ethernet cable from your computer to the "PC" port on the back of the phone. This allows both your phone and computer to share a single network drop.
- Connexió del telèfon: Connect the coiled handset cord to the handset and to the handset port on the phone.
- Muntatge de l'estand: Attach the phone stand to the back of the phone, ensuring it clicks securely into place.
3.2 Initial Boot-up and Configuration
Once powered on, the phone will initiate its boot-up sequence. This may take a few moments. The display will show the Cisco logo and then proceed to acquire network settings and register with your VoIP system. Configuration of the phone's features, such as line settings, speed dials, and other advanced options, is typically performed via a web-based interface accessible from a computer on the same network. Refer to your VoIP service provider's documentation or network administrator for specific configuration details.
