What is Perpetual PoE?

What is Perpetual PoE technology?

Perpetual PoE is a technology that allows devices to receive power from the network even when the PSE switch is rebooting. Currently, rebooting the switch causes a temporary loss of power on the ports, which leads to a complete reboot of all connected devices. This is very undesirable in the work environment. This feature is especially beneficial in critical applications such as security systems, industrial automation, and other applications where device uptime is crucial.

Traditional PoE (Power over Ethernet) technology, on the other hand, allows devices to receive power over the same Ethernet cable that is used for data transmission. This eliminates the need for separate power cables and reduces the need for additional electrical work. However, in traditional PoE networks, if the switch reboots, the devices that are connected to it will lose power, leading to downtime and potential data loss.

Advantages of Perpetual PoE

Perpetual PoE technology offers several advantages over traditional PoE networks. I name two here. The first is improved device uptime: Perpetual PoE technology allows devices to continue to receive power even in the event of a switch reboot, which improves overall device uptime and reduces downtime. 

Another is the increased reliability: By providing a secondary power supply, Perpetual PoE technology increases the reliability of the power supply to the devices and reduces the risk of power-related failures.

Applications of Perpetual PoE

Perpetual PoE technology can be used in a variety of applications where device uptime is crucial. Here are some of the main applications that can benefit from Perpetual PoE technology:

  1. Security Systems: Security systems such as CCTV cameras, access control systems, and intrusion detection systems rely on constant power to function properly. Perpetual PoE technology allows these systems to continue to receive power even in the event of a switch or power supply failure, which ensures that the systems remain operational and can continue to provide security.

  2. Industrial Automation: In industrial automation systems, such as manufacturing and process control systems, Perpetual PoE technology can ensure that devices remain powered on and operational even in the event of a power failure. This can help to prevent downtime and loss of production.

  3. Medical Devices: In healthcare applications, such as patient monitoring systems and diagnostic equipment, Perpetual PoE technology can ensure that devices remain powered on and operational, even in the event of a power failure. This can help to ensure the continuity of care for patients.

  4. Telecommunications: In telecommunications systems, such as base stations and other network infrastructure, Perpetual PoE technology can ensure that devices remain powered on and operational even in the event of a power failure. This can help to ensure continuity of service for customers.

  5. Emergency and Safety Systems: Emergency and safety systems, such as fire alarms and emergency lighting, rely on constant power to function properly. Perpetual PoE technology allows these systems to continue to receive power even in the event of a switch or power supply failure, which ensures that the systems remain operational and can continue to provide safety.

These are some examples of applications that can benefit from Perpetual PoE technology, in general, any application that relies on constant power to function properly can benefit from Perpetual PoE technology.

The future of Perpetual PoE

The future of Perpetual PoE technology looks promising as the demand for reliable and uninterrupted power supply for devices continues to grow. Potential improvements and advancements include increased efficiency, improved scalability, greater compatibility, advanced power management, and greater adoption.

In conclusion, Perpetual PoE technology is an important technology for ensuring the reliability and availability of devices in critical applications. It offers many benefits. With the technology still evolving and improving, it's likely that Perpetual PoE technology will become even more widely adopted in the future.
