Understanding PoE Switch And Its Types: Everything You Need To Know

PoE Switch

You probably know that Powered Devices (PDs) such as VoIP Phones, IP Cameras, Wireless Access Points (WAPs), etc. need both power and data to work. Pointing to the scenario when there was no PoE switch, there was a traditional way of using Non-PoE switches that only provided the data required for the powered devices. What about power? As stated earlier, power is also an essential factor when it comes to executing powered devices (PD). In that scenario, people using the PD had to connect another piece of equipment called a PoE Injector or other PSEs to a network, making networking a complicated process. To eradicate such hectic techniques in a PD networking system, PoE switches were invented.

A PoE switch is a PoE-compliant technology that provides both power and data to powered devices through an Ethernet cable. If your equipment is located in a place with insufficient outlets or network connections, PoE (Power over Ethernet) technology may be a viable option. PoE switches come in two different types: managed switches and unmanaged switches. Along with the increased use of gadgets comes an increase in cost and complexity. As a leading manufacturer of networking products in India, AE Connect offers cost-effective and high-performance managed and unmanaged PoE switches.

What distinguishes a managed PoE switch and an unmanaged PoE switch?

Control over the PoE network:

As the names indicate, the methodology of a managed switch differs significantly from an unmanaged switch. The ability to manage, prioritise, and control LAN traffic is made possible by a managed switch for the network administrator. Additionally, managed switches include enhanced capabilities that allow operators to recover data if the device or network fails. An unmanaged switch, on the other hand, is easy to use, functions similarly to a plug-and-play switch and enables powered devices to receive power and data without user involvement.

Features:

The following are frequently seen features in managed switches, although they might differ among manufacturers and models:

– SNMP & VLAN support

– Spanning tree protocol & QoS support

– Bandwidth rate limiting

– Port mirroring

Whereas the MAC address table is a special feature of unmanaged PoE switches. Keeping a MAC address table reduces the total number of broadcasts transmitted, minimizing the probability of collisions inside the domain.

Security:

Unmanaged switches are equipped with basic security elements, such as a locking port cover, to provide fundamental security and prevent any sort of direct manipulation of the device. Managed network switches, in contrast, come with cutting-edge technologies that make it easier to spot live threats, quickly neutralise them, and safeguard data and control. Managed switches can configure security features that unmanaged switches cannot.ย  802.1X authentication, port security, and private VLANs are among the capabilities available in managed switches. AE Connect offers the most secured PoE switches, whether they are unmanaged or managed.

Performance and Use

Even when used in a network of more than 100 IP cameras, managed PoE switches provide the best performance and are constantly open to configuration. When thereโ€™s a big network of powered devices in an organization, managed switches become the best-to-use PoE switches. While talking about unmanaged PoE switches, they can provide high performance in a network of up to 65 IP cameras, which makes them a good choice for start-ups and small-scale businesses. Since AE Connect has complete confidence in its best-in-class, high-performing PoE switches, AE Connect offers a warranty of three years and extended warranty support on all its managed and unmanaged PoE switches.

 

Costs:

The cost of managed PoE switches is higher due to their high-end features than that of unmanaged PoE switches, which are more widely available at lower prices. AE Connect, a renowned manufacturer of networking equipment in India, provides managed and unmanaged PoE switches that are both affordable and highly effective.

After reading the aforementioned points, you must have gotten an idea about the distinction between a managed and an unmanaged PoE switch. These switches, however, share some of the same characteristics, which are as follows.

  1. Multi-layer networking is achievable in both the managed and unmanaged switches which means multiple network-connected devices can interact with one another using them.
  1. Ethernet connections between managed and unmanaged switches are possible. Managed switches can be linked to other switches (managed or unmanaged), while unmanaged switches can be linked to each other over Ethernet.

 

What can the PoE switch power?

PoE switches are classified according to the standards that they support. You must be aware of the power requirements of your devices before picking your PoE switch. With the below information, you’ll be able to determine which standard and PoE switch the best meet your requirements.

– PoE switch that supports IEEE802.3af standard delivers up to 15.4W per port and is best suitable for low power consuming PDs like IP Phones, Basic IP Cameras, 802.11n APs, etc.

– PoE switch that supports IEEE802.3at standard delivers up to 30W per port and is best suitable for medium power-consuming PDs like IP Video Phones, PTZ HD IP Cameras, 802.11ac (WiFi 5) APs, Small Audio Speakers, etc.

– PoE switch that supports IEEE802.3bt standard delivers up to 60/90W per port and is best suitable for high power-consuming PDs like PTZ HD IP Cameras with Heaters, 802.11ax (WiFi 6) APs, Smart Building Lighting, Audio Systems, etc.

Different PoE switches from AE Connect come with the above-mentioned PoE standards, next-generation hardware, a robust power budget and a best-in-class design that delivers more power to the connected powered device.

Key factors to keep in mind when choosing a PoE switch:

When choosing the ideal PoE switch, strategic planning for organizational expansion and device usage is essential.

Before picking a PoE switch, it’s crucial to consider the network infrastructure and bandwidth, existing network equipment, present IoT, the locales of that equipment and IoT, the power setups and desired network system updates and extensions. These parameters will define the kind of PoE switch needed and whether converters or fiber optic transmission are required for improved bandwidth and long distances.

With the below points, you will get a fair idea of the important things to consider while picking a PoE switch.

Port Count:

How many ports the switch needs will depend on how many users the network has to accommodate; the larger the organisation, the more the ports needed. PoE switches typically include 8, 12, 16, 24, or 48 ports for Ethernet wiring and communication. Small or home networks often only need PoE switches with 8 to 16 ports. PoE switches of 24, 48, or more ports can accommodate the extensive and varied network system requirements of data centres, corporations, and large organisations.

Performance and Speed:

The technical specifications of the switch must be capable of supporting the network sufficiently if it is continually moving huge amounts of data, and includes wireless devices, multiple printers, real-time services, voice-over-internet, etc. In that scenario, only managed switches need to be installed for the traffic to be prioritised and managed.

Power Usage:

Along with the power used by the PoE switch, the overall power usage of all powered network devices must not exceed the operational capability of PoE switches. All powered network devices should be connected and powered at the same time, depending on the PoE switch’s port count and PoE switch type. With the proper PoE switch, data transmission can continue without interruption or signal loss. By carefully calculating the power budget, signal loss and power budget depletion can be prevented.

Emerging Network Expansion:

If the network and business are expected to expand, think about whether it will be more cost-effective to add new switches in the future, or whether one or two fully managed switches would likely be more beneficial over the long term since they can be manually configured and are more flexible.
