Cisco Desktop Collaboration Experience Power
Power Type
PoE power—Provided by a
switch through the Ethernet
cable attached to the phone

Power Outage

Your access to emergency service through the phone requires the phone to receive power. If an interruption
in the power supply occurs, Service and Emergency Calling Service dialing do not function until power is
restored. In the case of a power failure or disruption, you may need to reset or reconfigure equipment before
you can use the Service or Emergency Calling Service dialing.

Phone Power Reduction

You can reduce the amount of energy that the Cisco Desktop Collaboration Experience DX600 series device
consumes by using Power Save or EnergyWise (Power Save Plus) mode.

Power Save Mode

In Power Save mode, the backlight on the screen is not lit when the phone is not in use. The phone remains
in Power Save mode for the scheduled duration or until the user lifts the handset or presses any button. In the
Product Specific Configuration area of the Phone Configuration window on Cisco Unified Communications
Manager Administration, configure the following parameters:
Days Display Not Active
Specifies the days that the backlight remains inactive.
Display on Time
Schedules the time of day that the backlight automatically activates.
Display on Duration
Indicates the length of time that the backlight is active after the backlight is enabled by the programmed
schedule.

Guidelines
Cisco Desktop Collaboration Experience DX600 series devices support IEEE
802.3af Class 3 power on signal pairs and spare pairs.
Cisco Desktop Collaboration Experience DX600 series devices support IEEE
802.3at for external add-on devices.
To ensure uninterruptible operation of the phone, make sure that the switch
has a backup power supply.
Make sure that the CatOS or IOS version that runs on your switch supports
your intended phone deployment. See the documentation for your switch for
operating system version information.
Support for NG-PoE+: The Cisco Desktop Collaboration Experience DX600
series devices can draw more power than IEEE 802.3at, as long as there is
NG-PoE+ switch support.
