The filenames derive from the MAC address and description fields in the Phone Configuration window of

Cisco Unified Communications Manager. The MAC address uniquely identifies the phone.

For more information on phone configuration settings, see the "Cisco Unified IP Phone Configuration" chapter

in the Cisco Communications Manager Administration Guide.

Phone Startup Process

When connecting to the VoIP network, the Cisco Unified IP Phone 6901 and 6911 go through a standard

startup process that is described in the following list. Depending on your specific network configuration, not

all these steps may occur on your Cisco Unified IP Phone.

1 Obtain power from the switch. If a phone does not use external power, the switch provides in-line power

through the Ethernet cable attached to the phone. For more information, see

Manager Phone Addition Methods, on page 8

2 Configure VLAN. If the Cisco Unified IP Phone connects to a Cisco Catalyst switch, the switch informs

the phone of the voice VLAN defined on the switch. The phone needs to know the VLAN membership

before proceeding with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.

For more information, see

3 Obtain an IP address. If the Cisco Unified IP Phone uses DHCP to obtain an IP address, the phone queries

the DHCP server to obtainthe address. If you are not using DHCP in your network, you must assign static

IP addresses to each phone locally.

For more information, see

4 Access a TFTP server. In addition to assigning an IP address, the DHCP server directs the

Cisco Unified IP Phone to a TFTP Server. If the phone has a statically defined IP address, you must

configure the TFTP server locally on the phone; the phone then contacts the TFTP server directly.

You can also assign an alternative TFTP server to use instead of the one assigned by DHCP.

Note

For more information, see

5 Request the configuration file. The TFTP server stores configuration files that define parameters for

connecting to Cisco Unified Communications Manager and other information for the phone.

For more information, see

6 Load the stored phone image. The Cisco Unified IP Phone has nonvolatile flash memory to store 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 the software and hardware.

For more information, see

7 Contact Cisco Unified Communications Manager. The configuration file defines how the Cisco

Unified IP Phone communicates with Cisco Unified Communications Manager and provides a phone with

the load ID. After obtaining the file from the TFTP server, the phone attempts to make a connection to

the highest priority Cisco Unified Communications Manager on the list.
