We have only one DX-650 phone for testing. When phone goes into sleep mode it starts behave abnormal (in sleep mode its keep flickering or keep flashing continuously) when phone is out of sleep mode every thing works fine.
Is there any specific settings required for DX-650 sleep mode ? or what problem do cause this ?
Can u refer the DOC in Table 2 which talks about Sleep Mode
EnergyWise on the Cisco Desktop Collaboration Experience Setup
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 timer expires.
To wake up the phone press Lock. At the scheduled wake time, the system restores power to the phone, waking it up.
The following table explains the Cisco Unified Communications Manager Administration fields that control the EnergyWise settings. You configure these fields in Cisco Unified Communications Manager Administration in the Product Specific Configuration area of the Phone Configuration window Device >Phone.
