Yealink CP860 [23/417] Initialization process overview

Getting Started

To connect a PC or mobile device:

1. Connect one end of the 3.5mm jack cable to the PC/mobile port on the phone, and

connect the other end to the headset jack on the mobile device or the AUX/MIC

jack on the PC.

The initialization process of IP phones is responsible for network connectivity and

operation of IP phones in your local network.

Once you connect your IP phone to the network and to an electrical supply, the IP phone

begins its initialization process.

During the initialization process, the following events proceed:

Loading the ROM file

The ROM file resides in the flash memory of IP phones. IP phones come from the factory

with a ROM file preloaded. During initialization, IP phones run a bootstrap loader that

loads and executes the ROM file.

Configuring the VLAN

If IP phones are connected to a switch, the switch notifies IP phones of the VLAN

information defined on the switch (if using LLDP). IP phones can then proceed with the

DHCP request for their network settings (if using DHCP).
