Start Up Sequence
After the Cisco Unified IP Phone Expansion Module 7915 is
installed, upon startup the buttons all show a steady amber
light. The Cisco logo, load name, segment name, and download
percentage are displayed. After the firmware is installed, the
LCD screen refreshes and the buttons all go off and any line
appearances are displayed in the LCD screen. You can then start
using the Expansion Module.
