Cisco Unified IP Phone Power Injector
Integrated Power for Better Performance

Cisco Unified IP Phone Power Injector:

The Cisco Unified IP Phone Power Injector is a single-port midspan power injector with an integrated power supply that has been specifically designed and tested for use with all Cisco Unified IP Phones (including Gigabit versions). This product may be used asan alternative to the existing Cisco phone power supply (CP-PWR-CUBE-3=), and can support a maximum distance of 100 meters between an unpowered switch and a Cisco Unified IP Phone.

Product Overview

The Cisco® Unified IP Phone Power Injector increases the deployment flexibility of Cisco Unified IP phones by providing an alternative powering option to local power, multiport power patch panels, and inline-power-capable switches.

Cisco Unified IP Phone Power Injector (Front, Back, and Stacked Views)

The Cisco Unified IP Phone Power Injector is a midspan power injector designed and tested for use with Cisco Unified IP phones. The Cisco Unified IP Phone Power Injector sits between a switch port and the Cisco Unified IP phone, providing inline power capability to an unpowered switch port. It supports Cisco midspan power, IEEE 802.3af modes for supplying power to the attached phone, and 10/100/1000BASE-T Ethernet connections. Figure 2 shows the maximum distance of the Cisco Unified IP Phone Power Injector between a Cisco Unified IP phone and an Ethernet switch.
