IP Phone Selection
Appendix A, "IP Phone Models and Selection Criteria," and Appendix D, "IPT Design Phase: IP Phone Selection Questionnaire," to gather the end users' IP Phone requirements and to determine which IP Phone models you need for each site.Power and Environmental Infrastructure" section in Chapter 4 provides the information that you need to determine the additional hardware requirements, such as the number of inline power modules and the capacity of the power supplies required in the access layer switches to support the inline power to IP Phones.In the XYZ network, at the central sites, access layer switches are Catalyst 6500 switches that have inline power capable 10/100 line cards. All IP Phones connect to the access layer switches. The remote-site access devices are either inline power capable or upgradeable to support the inline power. XYZ decided to go with the Cisco inline power standard method to supply the power to IP Phones.
