According to a 2025 study on artificial intelligence (AI) in manufacturing from Redwood, an automation platforms leader, most manufacturers are exploring AI-driven automation, but only 20% are prepared to use it across their enterprise. The majority have automated less than 50% of their core operations, limiting their return on investment (ROI). The study explains that the stumbling block to full automation is a siloed environment that limits the flow of information. Almost 80% of manufacturers still rely on manual data entry to move data between systems.
Moving to more integrated automation on the factory floor requires a robust infrastructure capable of transmitting large volumes of data in real time. A fully integrated PoE factory floor enables seamless automation by delivering both power and high-speed data over a single Ethernet cable, bridging operational gaps without overhauling existing infrastructure.
Power over Ethernet (PoE) technology facilitates data delivery at speed, while powering devices cost-effectively. A PoE factory enables manufacturers to transition from siloed solutions to integrated automation while leveraging existing architecture.
What is Power over Ethernet (PoE)?
PoE technology allows power and data to be sent over a single Ethernet cable. The latest standards from the Institute of Electrical and Electronics Engineers (IEEE 802.3bt) define how eight copper wires or four twisted pairs should be configured for power and data transmission. Using Category 6 or higher Ethernet cables, factories can transmit gigabytes of data and power devices needing up to 90W without replacing their entire network.
PoE managed switches can automatically detect non-PoE devices and refrain from sending them power. Because the IEEE standards ensure backward compatibility, the latest technology can coexist with older infrastructures. The technology provides manufacturers with a migration path to full automation.
Building an Automated PoE Factory
Manufacturers often struggle to unify workflows, deliver accurate data, and scale operations efficiently. These challenges limit productivity gains from AI and automation. Factories that incorporate PoE devices into existing solutions can benefit from simplified infrastructure, increased reliability, and greater flexibility for integrated automation.
Simplified Infrastructure for a PoE Factory
A streamlined infrastructure is easier to install, manage, and maintain. Network expansion does not require additional electrical work to deploy new devices. Instead, network engineers can run Ethernet cable, connect devices, and configure them as needed. Fewer cables reduce complexity during troubleshooting, shortening the time to resolution.
Integrating technologies is not always straightforward. Factories often need workarounds to get components to communicate. Because of their backward compatibility, PoE solutions can bridge the gap between old and new technologies. They can also leverage existing devices through auto-detection of PoE and non-PoE endpoints, and eliminate power transmission to non-PoE devices.
Greater Flexibility on the Factory Floor
Many existing factories were not designed for AI, IoT expansion, or high-bandwidth data transmission. Even small infrastructure changes can be costly in legacy environments.
For example, upgraded equipment may require additional sensors to report friction-induced heat and prevent unnecessary shutdowns. However, certain locations may not support an external power source for sensors. Rather than paying for expensive rewiring, manufacturers can deploy PoE-enabled sensors that do not require a separate power supply. With greater flexibility, PoE solutions can be deployed in hard-to-reach locations or positioned for cost-effective network expansion.
Increased Reliability on the PoE Factory Floor
The 2025 survey found that 60% of automated factories saw a 26% reduction in unplanned downtime. AI’s predictive analytics used operational data collected by temperature, vibration, and humidity sensors to determine when equipment was at risk of failure. Without appropriately placed sensors, accurate data would be unavailable.
PoE technology increases reliability by using managed switches that auto-detect whether a connected device is responding and recycle the connection to bring it back online with minimal impact on operations. For critical activities, PoE solutions can be connected to an uninterruptible power supply (UPS) to ensure ongoing operations even during a power outage.
Improved Power Management
PoE systems can be configured to manage power going to specific connected devices in the network. Switches can stop delivering power to inactive or unresponsive devices, preventing power from being supplied to devices not in use. PoE supports power scheduling for connected devices and enables per-device power usage monitoring. Granular controls provide greater energy efficiency.
AI capabilities can optimize power consumption through data analysis and algorithms. Occupancy and lighting sensors can trigger AI-driven heating and cooling systems to lower temperatures and turn off lights to save power. AI can adjust conditions on the factory floor based on environmental and operational data.
Readily Scale Operations
PoE’s flexibility means factories can quickly scale operations. Whether it’s adding sensors or increasing surveillance, PoE-enabled devices can be deployed anywhere on the network. As an enterprise grows, it can leverage PoE’s plug-and-play capabilities for rapid implementation, enabling agile operations.
Deliver Accurate Data
AI-driven manufacturing relies on data to generate insights and predict behaviors. If data is missing or is inaccurate, the results can be faulty, leading to ineffective and even costly decisions. The latest PoE standards support transmission of gigabytes of data in seconds. With sufficient bandwidth, no data is lost because of excessive network traffic. Accurate transmissions improve network performance because messages do not have to be retransmitted, reducing the burden on an already overloaded network.
Unify Workflow
To achieve AI-driven automation, factories need unified workflows. Data transfer cannot be delayed while data is entered manually. AI requires complete, real-time information to realize its productivity gains. By using PoE technology, manufacturers can extend their networks to ensure accurate data collection and delivery cost-effectively.

Realizing a Fully Integrated PoE Factory
Manufacturing complexities make integrated automation challenging. Upgrading existing infrastructure to meet AI’s power and data demands can be time-consuming, disruptive, and costly. For example, a factory may operate on a local Ethernet network but connect to the outside world, including other company facilities, using fiber. Finding a solution, such as PLANET’s IGT-2205AT-E media converter, can ease the connectivity challenge.
These industrial-grade units are designed to operate in environments with extreme temperatures, ranging from -40 to 75 degrees Celsius. It has two copper and two fiber-optic ports in an IP40-rated case, and a redundant power system. Its features can help manufacturers realize an integrated PoE factory by leveraging existing technology, deploying advanced solutions, and integrating AI automation.
