Single-port PoE injector

The HP J9407B#ABA 1-port Power Injector delivers 802.3af PoE power to a single access point or network device. It is designed for locations where running an AC power supply or using a traditional PoE switch is impractical. The unit connects via one RJ-45 Ethernet output port and is finished in black. This accessory suits network installers and IT teams extending wireless coverage without new mains wiring.

Passive cooling and low draw

The injector operates without a fan, relying on passive convection for silent operation in office or ceiling-mount environments. Power consumption stays within the 802.3af limit of 45 watts delivered to the powered device. Green compliance is confirmed with RoHS certification, indicating restricted hazardous substances. No active cooling noise or high idle draw is introduced into the installation.

Replaces midspan or switch PoE

This injector upgrades a non-PoE switch or router by adding single-port PoE capability without replacing the core switch. It is worth deploying when only one or two access points need power and a full PoE switch is not justified. Buyers who need to power multiple devices from one unit or require 802.3at high-power PoE should consider a multi-port midspan or PoE switch instead.

Questions about this item

How do I connect the single RJ-45 output port on the J9407B#ABA injector to power an access point?

Plug the injector's RJ-45 output into the access point's PoE port using a standard Ethernet cable; the injector delivers 802.3af power so no separate AC adapter is needed at the AP.

Will the RoHS-compliant J9407B#ABA injector need any periodic maintenance or component replacement?

The unit has no moving parts or user-serviceable components; it is designed for continuous operation without scheduled maintenance or replacement intervals.

What is the maximum sustained power the J9407B#ABA can supply before its 802.3af limit is reached?

The injector is rated for the 802.3af standard, which provides up to 45 watts of power to the connected device under sustained load.
