Before You Power Up: Questions to Consider for Industrial PoE Solutions

Power over Ethernet simplifies networking by combining power and data into a single Ethernet cable, optimizing efficiency for advanced surveillance systems, industrial automation infrastructure, and high-performance wireless networks. This eliminates the need for additional power outlets and provides flexibility in device installations.

However, the demand for higher resolution devices surpasses the capabilities of 15-watt to 30-watt PoE devices. Ensuring compatibility between power power sourcing equipment (PSE) and powered devices (PDs) may not be convenient for industrial automation developments.

Imagine an upgraded PoE solution seamlessly accommodating higher power needs and ensuring PSE-PD compatibility. This evolution streamlines installations, reduces costs, and enhances adaptability in the face of technological advancements and operation expansions. In modern connectivity, let the PoE be the fuel for a more agile, efficient, and future-ready network infrastructure.

Key Considerations and Operational Strategies

PoE devices are designed to offer you valuable insights, aiding in the optimal maintenance of your PDs if you take a closer look at these usually ignored but significant details.

Strengthening Durability & Reliability

1. Should my PoE follow automation, railways, transportation, and energy industry standards?
In the context of industrial automation, transportation, and the energy industry, various standards apply to ensure safety, interoperability, and efficiency:

IEC 62443: Secures industrial automation and control systems by providing guidelines for robust cybersecurity measures.
NEMA TS-2: Specifies requirements for rolling stock traffic control systems, ensuring standardized functionality and interoperability.
IEC 61850: Addresses communication requirements for substation automation in the energy sector, establishing protocols for seamless data exchange and system integration.
EN 50121-4: Adheres to the electromagnetic compatibility (EMC) requirements related to emission and immunity of signaling and telecommunications apparatus installed in the railway environment, aiming to ensure that these systems operate reliably without interference from or to other equipment.

It's important to note that these industries often have sector-specific standards, and compliance with these standards is crucial for ensuring the reliability and safety of systems within each domain.

2. How to ensure that my PoE switches can withstand extreme temperatures and harsh environments?
EtherWAN’s hardened PoE switches ensure safe and reliable operation across a wide temperature range, from -40°C to +75°C. Most of the PoE switches are fanless, these switches are designed without internal fans, relying on passive cooling through ventilation holes. It leads to a significant reduction in power consumption and the risk of mechanical failures.

It is guaranteed that these switches can withstand high impact, thermal shock, and electrical noise resistance for optimal performance.

Achieving Seamless Compatibility

3. How can I identify a PoE solution capable of supporting my high-powered PDs?
IEEE 802.3af and IEEE 802.3at only provide 15.4 watts to 30 watts of power per port, which might be sufficient for some devices but can be limiting for high-power requirements.For devices like lighting and certain types of IP cameras, you would often consider using the high power PoE standard:IEEE 802.3bt (PoE++): Also known as 4-Pair PoE, offers even higher power levels, from 60 watts to 100 watts per port. This is especially useful for devices with significant power requirements, such as high-end PTZ (Pan-Tilt-Zoom) cameras and robust lighting solutions.

4. How many PoE ports do I need?
The number of PoE ports you need depends on the number of PDs you plan to power. Consider the power requirements of each device PD and ensure that the total power budget of your PoE switch can accommodate all devices simultaneously.

Confirm the total power consumption of all devices and ensure that the PoE switches have enough PoE power and power budget to support them.

Ease in Management

5. Can the PoE devices meet my band width requirements?
It's crucial to ensure sufficient bandwidth for optimal performance. Bandwidth determines the data-carrying capacity of the network, influencing the speed and reliability of data transmission.

Inadequate bandwidth can lead to network congestion, latency, and compromised device functionality. By prioritizing gigabit solutions, you guarantee smooth data transfer, support for high-resolution cameras & bandwidth-intensive devices, and a future-ready infrastructure that can adapt to increasing data demands.

6. Should I check the power consumption requirements before setting up my PDs?
Have you ever found yourself meticulously checking the power consumption of your PDs and configuring your PoE switches, only to realize it's a bit of a chore?

When considering the power requirements for various devices such as IIoT sensors, networked lighting systems, and IP cameras, the wattage can vary significantly. These devices swing between 15 watts to 90 watts.

PoE switches with automatic power detection do the job—no more manual inputs. IEEE 802.3bt guarantees automatic detection of power consumption, making configuration and deployment a smooth sail.

7. Can the PoE identify and remotely resolve power and transmission interruptions?
Consider a scenario where a critical IP camera, integral to a surveillance system, experiences a sudden power fluctuation. Without the PoE watchdog function, this disruption could go unnoticed, leaving a blind spot in security coverage.

While real-time alert promptly notifies you when unwanted redundant power fails to occur. Simultaneously, the system takes preemptive action to stabilize the power supply, ensuring continuous monitoring and averting potential security vulnerabilities. This scenario underscores the indispensable role of the PoE watchdog function and real-time alert in maintaining a robust and responsive surveillance infrastructure.
