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
