Power-saving mode
Your conference station supports the Cisco EnergyWise (EW) program. Your system administrator sets up
sleep (power down) and wake (power up) times for your conference station to save energy. In the sleep state,
the LED for the sound base Mute button becomes solid gray, and the DCU powers off.
Ten minutes before the scheduled sleep time, you receive a message that the conference station will power
down at a specific time. If the power-saving mode is enabled by your system administrator, you hear your
ringtone play. The ringtone plays according to the following schedule:
• At 10 minutes before power down, the ringtone plays four times
• At 7 minutes before power down, the ringtone plays four times
• At 4 minutes before power down, the ringtone plays four times
• At 30 seconds before power down, the ringtone plays 15 times or until the phone powers down
If your conference station is inactive (idle) at the sleep time, it powers down. If your conference station is
active (for example, on a call), it waits until it has been inactive for a period of time before removing power.
After the conference station goes to sleep, press the Mute button on the sound base to wake the conference
station up. You cannot wake the conference station using the DCU. After it is inactive for a period of time,
the conference station goes back to sleep. At the set wake time, the conference station powers up.
Wake and sleep times are also linked to the configured days that you normally work. If your requirements
change (for example, your work hours or work days change), contact your system administrator to have your
conference station reconfigured.
For more information about EnergyWise and your conference station, contact your system administrator.
