CP-PWR-CUBE-3 Description
The CP-PWR-CUBE-3 is a Cisco Power Cube 3 local AC-to-DC power adapter for Cisco phones on desks and in rooms without PoE. The adapter powers the Cisco Unified IP Conference Phone 8831 and the Cisco Unified IP Phone 6900 Series, and it connects to the wall through a separate Cisco AC country cord. A Cisco Unified IP Conference Phone 8831 daisy-chain configuration requires a power cube.

Application Scenarios
In a meeting room where the access switch cannot supply 802.3af PoE, the adapter powers a Cisco Unified IP Conference Phone 8831 from a wall outlet through the matching country cord.
When two Cisco Unified IP Conference Phone 8831 units are daisy-chained across a larger table, the adapter supplies the local power that configuration requires.

CP-PWR-CUBE-3 is the local power adapter documented for the Cisco Unified IP Conference Phone 8831 and the Cisco Unified IP Phone 6900 Series, while CP-PWR-CUBE-4 is the AC-to-48V DC power cube listed as an optional supply for the Cisco IP Phone 8800 desk phones. The 8831 daisy-chain configuration requires a power cube and is documented with CP-PWR-CUBE-3, so those room designs stay on this model. CP-PWR-CUBE-4-S is the CP-PWR-CUBE-4 design with a power switch and shares its 8800 Series phone context, so 8800 desk phones that need a switched adapter use CP-PWR-CUBE-4-S.
Ordering Checklist
- Cisco Unified IP Conference Phone 8831: CP-PWR-CUBE-3= powers the 8831 locally and is required for a daisy-chain configuration. A two-unit 8831 room design without the power cube cannot be daisy chained.
- Cisco Unified IP Phone 6900 Series: CP-PWR-CUBE-3= is the local adapter for 6900 phones as an alternative to 802.3af PoE. A 6900 desk without PoE needs a local adapter.
