The initialization process of the IP phone is responsible for network connectivity and
operation of the IP phone 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 take place:
Loading the ROM file
The ROM file resides in the flash memory of the IP phone. The IP phone comes from the
factory with a ROM file preloaded. During initialization, the IP phone runs a bootstrap
loader that loads and executes the ROM file.
Configuring the VLAN
If the IP phone is connected to a switch, the switch notifies the IP phone of the VLAN
information defined on the switch (if using LLDP or CDP). The IP phone can then proceed
with the DHCP request for its network settings (if using DHCP).
adapter. Make sure the switch/hub is PoE-compliant.
The IP phone can also share the network with another network device such as a PC
(personal computer). It is an optional connection.
Important! Do not unplug or remove the power while the IP phone is updating firmware
