24-Port 1U Rack Mount Passive PoE Injector

Model : LNK-POE-24P

Overview

The device in focus is a high-density 24-Port 1U Rack Mount Passive PoE Injector, engineered for large-

scale network deployments—capable of delivering stable remote power to up to 24 terminal devices

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

dedicated 24-Port 1U Rack Mount Passive PoE Injector, it adopts a 1U standard rack-mount design,

seamlessly fitting into data center server racks or network cabinets to optimize space utilization and

align with industrial-grade equipment room deployment norms.

This 24-Port 1U Rack Mount Passive PoE Injector serves as a cost-efficient upgrade solution to add

PoE capabilities to any non-PoE Ethernet switch or router, eliminating the need for costly infrastructure

replacement. It specializes in injecting electrical power into CAT-5, CAT-6, or CAT-7 Ethernet cables,

leveraging the mature passive PoE transmission mechanism: standard Ethernet uses 2 of the 4 twisted

pairs for data, while the injector utilizes 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 24 ports features

isolated power output, avoiding mutual signal disruption or cascading failures even when fully loaded

with devices.

Widely compatible with mainstream network equipment, the 24-Port 1U Rack Mount Passive PoE Injector

is ideal for powering high-density device clusters, including 4K IP cameras (dome, bullet, and high-speed

PTZ models), enterprise-grade IP videophones with multi-line support, WiFi 6/6E access points, and small

IoT gateways. Its 24-port configuration perfectly suits large-scale scenarios such as campus-wide surveillance

systems, multi-floor office network coverage, chain retail regional headquarters, and industrial park IoT device

deployments—centralizing power management and drastically reducing cable clutter.

Designed for operational efficiency and cost savings, this 24-Port 1U Rack Mount Passive PoE Injector supports

plug-and-play operation with no software configuration required, enabling rapid deployment by on-site technicians.

It eliminates the need for 24 separate power adapters and extra electrical wiring, slashing material costs and

installation manpower by over 60%. Equipped with a rugged metal chassis for heat dissipation and structural

stability, it ensures 24/7 reliable operation in high-load environments. Whether deployed in medium-to-large

enterprises, educational institutions, or smart city sub-systems, the 24-Port 1U Rack Mount Passive PoE Injector

combines high port density, rack-mount convenience, and passive PoE reliability to deliver a scalable, budget-

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

Features

► Panel 24 integrating passive POE injector suitable for powering up to 24 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
