Cisco AIR-PWRINJ7= at a Glance

High-Power Multigigabit PoE Solution

The Cisco AIR-PWRINJ7= provides a dedicated power delivery solution for compatible Cisco access points when sufficient PoE power is not available directly from the network switch.

The injector receives Ethernet data from the network and combines the data with electrical power before delivering both through a single Ethernet cable to the connected wireless access point.

Multigigabit Ethernet Connectivity

AIR-PWRINJ7= supports Ethernet connectivity at speeds ranging from 10 Mbps through 5 Gbps. This allows compatible access points to maintain high-speed wired uplink connectivity while receiving power through the same Ethernet connection.

IEEE 802.3bt PoE Power Delivery

The Cisco AIR-PWRINJ7= is designed for higher-power wireless access point deployments. It provides up to 50W of PoE power using IEEE 802.3bt technology.

• IEEE 802.3bt compliant power delivery
• Up to 50W PoE output
• 56V DC rated output
• 54–57V DC output range
• Maximum output current up to approximately 1.161A

AIR-PWRINJ7= Dimensions

The Cisco AIR-PWRINJ7= measures approximately 140 × 65 × 38.5 mm, making it suitable for compact external midspan PoE installations.

Easy PoE Deployment

AIR-PWRINJ7= can be installed between a network switch and a compatible Cisco access point. The injector receives Ethernet data from the network and adds PoE power before sending both through the Ethernet cable connected to the access point.
