Phone Configuration Files; Phone Startup Process - Cisco DX650 Administration Manual

Phone Configuration Files

The TFTP server stores the phone configuration files that define parameters for connecting to Cisco
Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications
Manager that requires the phone to be reset, a change is automatically made to the configuration file for the
phone.
Configuration files also contain information about the image load that the phone should be running. If this
image load differs from the one that is currently loaded on a phone, the phone contacts the TFTP server to
request the required load files.
A phone accesses a default configuration file, named XmlDefault.cnf.xml, from the TFTP server when the
following conditions exist:
• You enable autoregistration in Cisco Unified Communications Manager.
• You have not added the phone to the Cisco Unified Communications Manager database.
• The phone is registering for the first time.
If the device security mode in the configuration file is set to Authenticated or Encrypted, but the phone
Note
has not received a CTL or ITL file, the phone makes four attempts to obtain the file so the phone can
register securely.
If autoregistration is not enabled and Cisco DX650 has not been added to the Cisco Unified Communications
Manager database, Cisco DX650 registration request will be rejected. Cisco DX650 displays either Telephone
service is unavailable or Lost connection to the server on the screen.
Cisco DX650 accesses the configuration file named SEPmac_address.cnf.xml, where mac_address is the
Ethernet MAC address of Cisco DX650. The description field in the Phone Configuration window of Cisco
Unified Communications Manager Administration is prepopulated when the device is first configured. The
MAC address uniquely identifies the Cisco DX650 device.

Phone Startup Process

When connecting to the VoIP network, the Cisco Desktop Collaboration Experience DX600 series phone
goes through a standard startup process. Depending on your specific network configuration, only some of
these steps may occur on your Cisco DX650.
1 Obtain power from the switch. If a phone is not using external power, the switch provides inline power
through the Ethernet cable that is attached to the phone. The Detecting network... screen appears for about
30 seconds.
The phone attempts to detect an Ethernet connection. If an Ethernet connection is detected but there is no
IP address assigned, the user is prompted to contact the administrator for assistance. If an Ethernet
connection is not found, the phone attempts to establish a wireless network connection.

2 (For a Cisco DX650 in a wireless LAN only) Scan for an access point. The Cisco DX650 scans the RF
coverage area with the radio. The phone searches the network profiles and scans for access points that
