Cisco Aironet AIR-PWRINJ3 Power Injector
Brand: Cisco · SKU: AIR-PWRINJ3 · MPN: AIR-PWRINJ3 · Category: Networking
The Cisco AIR-PWRINJ3 is a 15W Aironet Power Injector designed to increase wireless LAN deployment flexibility for Cisco Aironet Access Points and Bridges by providing an alternative powering option to local power or inline power-capable switches. It combines 48-VDC power (supplied by an external power supply or alternative source) with the data signal, sending both to the connected device over Ethernet. It is compatible with Cisco AP models 1100, 1130AG, 1200, 1230AG, 1240AG, and 521. It uses the unused wires in the Category 5 cable (pins 4/5 and 7/8) to supply inline 48-VDC power. Note: Some sources indicate this model supports older 10/100BASE-TX, while others suggest newer PoE standards like 802.3af/at/bt supporting up to 60W, which may refer to a similarly named, but technically different, newer model (AIR-PWRINJ3=). Based on the primary results for AIR-PWRINJ3, the output power is 15W and interfaces are 10/100BASE-TX.
