Table 2-3 Cisco Unified IP Phone Startup Process
Process Step and Purpose
Step 1 Obtaining Power from the Switch.
If a phone is not using external power, the switch
provides in-line power through the Ethernet cable
attached to the phone.
Step 2 The Cisco IP Phone has non-volatile Flash memory
in which it stores firmware images and
user-defined preferences. At startup, the phone
runs a bootstrap loader that loads a phone image
stored in Flash memory. Using this image, the
phone initializes its software and hardware.
Step 3 Configuring VLAN.
If the Cisco IP Phone is connected to a Cisco
switch, the switch next informs the phone of the
voice VLAN defined on the switch port. The phone
needs to know its VLAN membership before it can
proceed with the Dynamic Host Configuration
Protocol (DHCP) request for an IP address.
If a third-party switch is used and VLANs are
configured, the VLAN on the phone must be
manually configured.
