Cambium N000045L056A PoE injector for wireless

The Cambium Networks N000045L056A is a Power over Ethernet injector designed to supply both data and power over a single Gigabit Ethernet cable. It accepts a 24 V DC input and delivers a 56 V DC output at 625 mA, compliant with the 802.3at standard. This device is built for deploying wireless access points and other powered devices where AC outlets are unavailable.

Installers needing 24 V DC input with 802.3at output

This injector suits network installers who have a 24 V DC power source on site and require standard 802.3at PoE+ delivery to compatible wireless equipment. It is not intended for environments where only AC mains power is present or for devices that demand a higher current budget than the 625 mA rated output.

24 V DC to 56 V DC conversion at Gigabit speeds

The defining specification is the voltage conversion from a 24 V DC input to a regulated 56 V DC output while maintaining Gigabit Ethernet throughput. This specific input and output voltage pairing determines whether the unit matches the power infrastructure and the powered device requirements at the installation point.

Questions about this item

What does the 802.3at standard cap the output at for this injector?

The injector delivers 56 VDC at 625 mA, staying within the 802.3at power budget for compatible wireless devices.

What physical mounting features does the N000045L056A include?

The compact housing has integrated wall-mount tabs with keyhole slots for direct screw mounting on a flat surface.

How is the injector installed and what step is often missed?

Connect the 24 VDC source to the DC input, then run a Gigabit Ethernet cable from the data-out port to the powered device; the step often missed is verifying the 24 VDC supply is live before plugging in the Ethernet link.
