Providing Power to the Conference Station Chapter 2 Preparing to Install the Conference Station on Your Network Understanding How the Conference Station Interacts with Cisco Unified Communications Manager Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco Unified Communications Manager software sets up and tears down calls between conference stations, integrating traditional private branch exchange (PBX) functionality with the corporate IP network. Cisco Unified Communications Manager manages the components of the IP telephony system-the conference stations, the access gateways, and the resources necessary for such features as call conferencing and route planning. Cisco Unified Communications Manager also provides: • Firmware for conference stations • Authentication and encryption (if configured for the telephony system) • Configuration file • Conference station registration • Call preservation, so that a media session continues if signaling is lost between the primary Cisco Unified Communications Manager and a conference station For information about configuring Cisco Unified Communications Manager to work with the IP devices described in this chapter, refer to Cisco Unified Communications Manager Administration Guide, Cisco Unified Communications Manager System Guide, and to Cisco Unified Communications Manager Security Guide. For an overview of security functionality for the conference station, see the "Understanding Security Features for Conference Stations" section on page 1-7. Note If the conference station model that you want to configure does not appear in the Phone Type drop-down list in Cisco Unified Communications Manager Administration, go to the following URL and install the latest support patch for your version of Cisco Unified Communications Manager: http://www.cisco.com/kobayashi/sw-center/sw-voice.shtml Related Topic • Telephony Features Available for the Conference Station, page 5-1 Providing Power to the Conference Station The conference station can be powered with external power or with Power over Ethernet (PoE). External power is provided through a separate power supply. PoE is provided by a switch through the Ethernet cable attached to a conference station. Note When you install a conference station that is powered by an optional external power supply, do the following: • Use a power interface cable to attach to the PoE cable and LAN wall port. See the "Installing the Conference Station" section on page 3-4 for instructions on how to attach the power interface cable. • Connect the power supply to the conference station and to a power outlet before you connect the Ethernet cable to the conference station. When you remove a conference station that is powered with external power, disconnect the Ethernet cable from the conference station before you disconnect the power supply.
