Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network Understanding the Phone Startup Process Table 2-3 Cisco Unified IP Phone Startup Process Step Description Related Topics 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. See the "Providing Power to the Cisco Unified IP Phone s 7906G and 7911G" section on page 2-4. See the "Resolving Startup Problems" section on page 9-2. 2. Loading the Stored The Cisco IP Phone has non-volatile Flash Phone Image. 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. See the "Resolving Startup Problems" section on page 9-2. 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. See the "Network Configuration Menu" section on page 4-7. See the "Resolving Startup Problems" section on page 9-2. 4. Obtaining an IP Address. If a third-party switch is used and VLANs are configured, the VLAN on the phone must be manually configured. If the Cisco IP Phone is using DHCP to obtain an IP address, the phone queries the DHCP server to obtain one. If you are not using DHCP in your network, you must assign static IP addresses to each phone locally. See the "Network Configuration Menu" section on page 4-7.
