12-Port 1U Rack Mount Passive PoE Injector with Power couples: 4.5 (positive pole) / 7.8 (negative pole)

12-Port 1U Rack Mount Passive PoE Injector

Model : LNK-POE-12P

Overview

The device in focus is a high-density 12-Port 1U Rack Mount Passive PoE Injector, engineered for medium-

to-large-scale network deployments—capable of delivering remote power to up to 12 terminal devices

simultaneously via Ethernet wiring, with transmission distance extending to 100 meters (328 ft). As a dedicated

12-Port 1U Rack Mount Passive PoE Injector, it features a 1U standard rack-mount design, perfectly fitting into

data center server racks or network cabinets to save space and align with standardized 机房 (equipment room)

deployment requirements.

This 12-Port 1U Rack Mount Passive PoE Injector serves as a cost-effective upgrade tool to add PoE capabilities

to any non-PoE Ethernet switch or router, eliminating the need to replace existing network infrastructure. It specializes

in injecting electrical power into CAT-5, CAT-6, or CAT-7 Ethernet cables, adopting the mature passive PoE transmission

mechanism: standard Ethernet uses 2 of the 4 twisted pairs for data, while the injector leverages unused pins 4/5 for

positive power and 7/8 for ground—ensuring zero interference between 10/100M data transmission and power delivery.

Each of its 12 ports operates with isolated power output, avoiding mutual signal disruption or cascading failures even

when fully loaded.

Widely compatible with mainstream network equipment, the 12-Port 1U Rack Mount Passive PoE Injector is ideal for

powering IP cameras (dome, bullet, or high-definition PTZ models), enterprise-grade IP videophones, dual-band WiFi 6

access points, and other passive PoE-enabled devices. Its 12-port configuration supports centralized power supply for

large-scale clusters—such as a 12-camera office building surveillance system, multi-floor retail WiFi coverage network,

or campus classroom IP communication setup—greatly reducing cable clutter and simplifying power management.

Designed for operational efficiency and cost savings, this 12-Port 1U Rack Mount Passive PoE Injector supports plug

-and-play operation with no software configuration required. It eliminates the need for 12 separate power adapters

and extra electrical wiring, drastically cutting material costs and on-site installation manpower. Whether deployed in

small-to-medium enterprises, educational institutions, or chain retail headquarters, its combination of 12-port capacity,

1U rack-mount convenience, and passive PoE reliability makes the 12-Port 1U Rack Mount Passive PoE Injector a flexible,

budget-friendly solution for extending power and network connectivity to distributed edge devices.

Features

► Panel 12 integrating passive POE injector suitable for powering up to 12 devices.

► The RJ45 connectors on one side are connected Ethernet ports with no power (switch) on the opposite side of the device used to connect power for Ethernet cable.

► Are used to power the two unused pairs of the Ethernet cable

► Power couples: 4.5 (positive pole) / 7.8 (negative pole)

► 19” 1U Rack Mount
