Power Outage

Your accessibility to emergency service through the conference station is dependent on the
conference station being powered. If there is an interruption in the power supply, Service and Emergency
Calling Service dialing will not function until power is restored. In the case of a power failure or
disruption, you may need to reset or reconfigure equipment before using the Service or Emergency
Calling Service dialing.

Understanding Conference Station Configuration Files

Configuration files for a conference station are stored on the TFTP server and 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 conference station to be reset, a change is
made to the conference station's configuration file automatically.
Configuration files also contain information about which image load the conference station should be
running. If this image load differs from the one currently loaded on a conference station, the conference
station contacts the TFTP server to request the required load files.
