Schedule Power Save Plus (Energywise) On Cisco Ip Phone - Cisco 7821 Administration Manual

Schedule Power Save Plus (EnergyWise) on Cisco IP Phone

To reduce power consumption, configure the phone to sleep (power down) and wake (power up) if your system
includes an EnergyWise controller.
You configure settings in Cisco Unified Communications Manager Administration to enable EnergyWise and
configure sleep and wake times. These parameters are closely tied to the phone display configuration parameters.
When EnergyWise is enabled and a sleep time is set, the phone sends a request to the switch to wake it up at
the configured time. The switch returns either an acceptance or a rejection of the request. If the switch rejects
the request or if the switch does not reply, the phone does not power down. If the switch accepts the request,
the idle phone goes to sleep, thus reducing the power consumption to a predetermined level. A phone that is
not idle sets an idle timer and goes to sleep after the idle timer expires.
To wake up the phone, press Select. At the scheduled wake time, the system restores power to the phone,
waking it up.
