The Cisco^®Multigigabit 802.3bt Power Injector(Figure 1) is a reliable, standards-compliant power injector capable of powering the latest high-performance access points and other network devices.

One of the main limitations in designing your wireless network is the availability of power. Running power cabling is also a primary cost driver of wireless installations. The Cisco Power over Ethernet (PoE) Injector allows delivery of both data and power to a Cisco access point over a single Ethernet cable, allowing deployment of devices exactly where they are needed to provide the best wireless coverage at a much lower installation cost.

The Cisco 802.3bt PoE Injector provides fully compliant 802.3bt detection, with disconnect, short-circuit, and overload protection to ensure that only 802.3bt, 802.3at, and 802.3af devices receive power, and that non-compliant devices are not accidentally damaged. Using this injector, it is possible to power the latest generation of 802.11ax devices that require higher power as well as providing multigigabit support.

Regardless of the deployment scenario, powering Cisco devices with 802.3bt Power over Ethernet with multigigabit is a flexible and low-cost method to simplify the installation process while ensuring that network design is not compromised by power availability limitations.
