Understanding the Startup Process
When connecting to the VoIP network, the Cisco Unified IP Conference Station
goes through a standard startup process.
Table 1-2 describes the startup process.

Startup Process Step Description
1 . Loading the Stored Station
Image
The Cisco Unified IP Conference Station has non-volatile Flash
memory in which it stores firmware images and user-defined
preferences. At startup, the Cisco Unified IP Conference Station
runs a bootstrap loader that loads a station image stored in Flash
memory. Using this image, the station initializes its software and
hardware.
2. Configuring VLAN If the Cisco Unified IP Conference Station is connected to a Cisco
Catalyst switch, the switch next informs the conference station of
the voice virtual local area network (VLAN) defined on the switch.
The Cisco Unified IP Conference Station needs to know its VLAN
membership before it can proceed with the Dynamic Host
Configuration Protocol (DHCP) request for an IP address.
3 . Obtaining an IP Address If the Cisco Unified IP Conference Station is using DHCP to obtain
an IP address, the station queries the DHCP server to obtain one.
4 .
Accessing TFTP Server In addition to assigning an IP address, the DHCP server also points
the Cisco Unified IP Conference Station to a TFTP server. You
must configure option 150 on the DHCP server for the TFTP
information to be passed from the server to the client.
If the Cisco Unified IP Conference Station has a statically-defined
IP address, you must manually configure the IP address of an
alternate TFTP server; the Cisco Unified IP Conference Station
uses this alternate TFTP server to receive its information.
