Chapter 2 Preparing to Install the Conference Station on Your Network Understanding the Conference Station Startup Process A conference station accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when these conditions exist: • You have enabled auto-registration in Cisco Unified Communications Manager • The conference station has not been added to the Cisco Unified Communications Manager Database • The conference station is registering for the first time If auto registration is not enabled and the conference station has not been added to the Cisco Unified Communications Manager Database, the conference station registration request will be rejected. In this case, the conference station will reset and attempt to register repeatedly. If the conference station has registered before, the conference station will access the configuration file named SEPmac_address.cnf.xml, where mac_address is the Media Access Control (MAC) address of the conference station. Understanding the Conference Station Startup Process When connecting to the VoIP network, the conference station goes through a standard startup process, as described in Table 2-4. Depending on your specific network configuration, not all of these process steps may occur on your conference station. Table 2-4 Conference Station Startup Process Process Step Description Related Topics 1. Obtaining power from the switch If a conference station is not using external power, the switch provides in-line power through the Ethernet cable attached to the conference station. See the "Providing Power to the Conference Station" section on page 2-2. See the "Resolving Startup Problems" section on page 9-2. 2. Loading the stored conference station image The conference station has non-volatile Flash memory in which it stores firmware images and user-defined preferences. At startup, the conference station runs a bootstrap loader that loads a conference station image stored in Flash memory. Using this image, the conference station initializes its software and hardware. See the "Resolving Startup Problems" section on page 9-2. 3. Configuring VLAN If the conference station is connected to a See the "Network Configuration Menu" Cisco switch, the switch next informs the section on page 4-5. conference station of the voice VLAN defined on See the "Resolving Startup Problems" section the switch port. The conference station needs to on page 9-2. know its VLAN membership before it can proceed with the DHCP request for an IP address. 4. Obtaining an IP address If the conference station is using DHCP to obtain an IP address, the conference station queries the DHCP server to obtain one. If you are not using DHCP in your network, you must assign static IP addresses to each conference station locally. See the "Network Configuration Menu" section on page 4-5.
