The advantages of utilizing Power over Ethernet technology for your network are enhancing growth and maintenance capabilities. However, considerations like anticipated organizational development and device usage must be carefully considered when choosing the best PoE switch.
This article will explore the considerations that will guide you in choosing the ideal POE switch for your requirements. There is something here for everyone, regardless of expertise level as a network administrator or integrator or whether you are new to PoE.
What is the PoE switch?
A Power over Ethernet (POE) switch is a networking device that delivers both power and data to compatible devices through standard Ethernet cables. Often utilized for devices such as IP cameras, VoIP phones, and wireless access points, POE switches remove the requirement for separate power supplies, resulting in cleaner and more economical installations.
Types of PoE switch
Before getting into specifications, it's essential to recognize the different types of POE switches
Type 1 PoE
Brief information: Type 1 Power over Ethernet (PoE), defined by the IEEE 802.3af standard, delivers power up to 15.4 watts to devices over standard Ethernet cabling (Category 5 or higher). It allows network devices, such as IP cameras, VoIP phones, and wireless access points, to receive both data and power through a single cable, simplifying installation and reducing the need for separate power supplies. Type 1 PoE provides a maximum power output of 12.95 watts at the powered device, considering some power loss in the cable. This standard has facilitated the widespread adoption of PoE technology in various applications, enabling more flexible network designs and efficient power management.
Name: 2-Pair PoE, PoE The IEEE 802.3af standard 15.4W is the maximum port power.
Type 2 PoE
Brief information: Type 2 Power over Ethernet (PoE), defined by the IEEE 802.3at standard, enhances the capabilities of the original PoE by delivering power levels up to 30 watts over standard Ethernet cabling (Category 5e or higher). This allows it to support a wider range of devices that require more power, such as PTZ (pan-tilt-zoom) cameras, advanced wireless access points, and other high-powered network devices. Type 2 PoE can provide up to 25.5 watts to the powered device after accounting for power loss in the cable. This increased power capacity facilitates the deployment of more complex and energy-intensive applications in networking environments, while still maintaining the convenience of using a single cable for both data and power.
Name: PoE+The IEEE 802.3at standard 30W is the maximum port power.
Type 3 PoE
Brief information: Type 3 Power over Ethernet (PoE), defined by the IEEE 802.3bt standard (also known as PoE+), further expands power delivery capabilities, allowing up to 60 watts of power over Ethernet cabling (Category 5e or higher). This standard is particularly beneficial for high-demand devices, such as multi-band wireless access points, advanced security cameras, and LED lighting systems. Type 3 PoE can deliver up to 51 watts to the powered device, accommodating the increasing energy needs of modern network applications. By utilizing all four pairs of wires in a standard Ethernet cable for power transmission, Type 3 PoE supports a broader range of devices while simplifying installations and reducing wiring complexity, enabling enhanced flexibility in network infrastructure.
Name: PoE++, 4P PoE, 4-pair PoE, UPOE The IEEE 802.3bt standard 60W is the maximum port power.
Type 4 PoE
Brief information: Type 4 Power over Ethernet (PoE), specified by the IEEE 802.3bt standard, is the most advanced PoE classification, capable of delivering up to 100 watts of power over Ethernet cabling (Category 5e or higher). This standard is designed to support high-power applications such as high-performance wireless access points, video conferencing systems, and IoT devices requiring significant power for operation. Type 4 PoE can provide up to 71 watts to the powered device, effectively accommodating the growing demand for power-hungry technologies in modern networking environments. By utilizing all four pairs of wires in a cable, Type 4 PoE enhances flexibility and efficiency in installations, allowing for the deployment of a wide variety of devices without the need for separate power supplies, streamlining infrastructure, and reducing overall costs.
Name: PoE with Higher Power The IEEE 802.3bt standard 100W is the maximum port power.
How to choose the right PoE switch
Selecting the appropriate PoE switch requires careful consideration of future device usage and organizational expansion. As discussed below, some factors should be considered when choosing the right PoE switch.
Port Density
PoE network switches come in various configurations, typically featuring 8, 12, 16, 24, 48 ports, or more. The choice largely depends on the number of end devices your network requires. An 8-port POE switch is ideal for home use, while a 48-port switch is commonly used in enterprises and data centers, where it needs to connect numerous networking devices. However, it's also prudent to consider additional ports to accommodate future business growth.
Data rate
Your current network speed or planned upgrade significantly influences the appropriate POE switch choice. Certain POE switches are compatible with standard Ethernet speeds (10Base-T), Fast Ethernet (10Base-T and 100Base-T), Gigabit Ethernet (1000Base-T), and even higher speeds like 1G and 10G. For example, a standard power switch would suffice if you use essential devices operating on 10Base-T. However, for a setup involving high-speed applications such as video conferencing for data-intensive applications, a gigabit poe sweet could be more appropriate.
Power consumption
The total power consumption of all power network devices must fall with the PoE switch in operation, including the power used by the switch. Depending on the number of forces and the type of PoE switch, it is essential that all connected devices can receive power simultaneously. For example, if you have an 8-port PoE switch with a total power budget of 60 Watts and plan to connect to IP cameras that each require 15 watts, you need to ensure the switch can handle the cumulative demand of 60 Watts without exceeding its limit.
Power budget
Each PoE switch has a maximum power budget that dictates how much power can be allocated to connected devices. Assess the power needs of all devices, such as IP cameras and phones, to ensure their total is within the switch's budget. For example, if the budget is 100 watts, ensure the combined devices do not exceed that limit.
Conclusion
Selecting an appropriate PoE switch is essential for enhancing your network performance and ensuring effective power distribution to your devices. By evaluating these factors, such as power budget, power consumption data rate and port density, you can make a well-informed choice that addresses your current and future networking requirements.
