The AIR-PWRINJ7 is a Cisco Multigigabit 802.3bt Power Injector. It’s designed to provide Power over Ethernet (PoE) to devices that require higher power levels, such as modern Cisco Catalyst access points. This injector supports multigigabit Ethernet speeds, ensuring that data transfer isn’t bottlenecked by the power delivery. It is very useful for situations where running new power cables is difficult or expensive.
