In this article, we will be talking about some of the best PoE switches and injectors available out there on the market. These two are essential components in building or modifying your LAN network; especially for POE devices. They help you to use PoE functionality. Before we discuss the differences between POE switch and injector, let us first understand what PoE functionality is.
Power over Ethernet (PoE):
The term PoE is used to describe several networking standards and ad-hoc systems. Altogether, these standards allow passing electricity through the twisted pair (commonly used in most LAN networks) along with the data. It eliminates the requirement of additional power cord since a single twisted pair cable is enough for providing both data connection and required electricity. This technique is commonly used to power various networking devices such as Wireless Access Points (WAP), IP Camera, VoIP phones, etc.
PoE Switch v/s PoE Injector Difference:
What is PoE Switch:
PoE switch provides the same functionality any conventional network switch does. However, the only difference is that a PoE switch comes with build in Power over Ethernet (PoE) injection. Whenever you connect such PoE switch with other networking devices, it automatically checks if these devices are PoE compliant and power them up if they are. Thus, using a PoE switch is the handy way of adding PoE functionality to your network.
What is PoE Injector:
PoE indicators are generally used for adding PoE capability to existing Non-PoE network links. Using PoE injector, we can activate both Poe injector and Non-PoE Ethernet devices. When deploying a network, injectors are the most versatile solution since they are handy when the number of required PoE ports are limited. PoE injectors are as well used for adding PoE to a specific device on the network.
What to choose?
You should remember following aspects while choosing a PoE Injector or Switch:
PoE switches do not offer additional ports and require a little modification to existing networks. On the other hand, PoE injectors do not expect much change on the net, and they can be easily mounted anywhere
If there are only a few devices you need to power up, you should go with the injector. However, if the requirement is high or you need to add PoE to the entire network, then we recommend PoE switches
If PoE switch goes down, all connected devices will go down. However, in case an injector goes down, only one device will be affected
Replacing a PoE injector is simple, however, replacing a PoE switch will cause production downtime on active network
This might be enough for understanding significant differences between PoE switches and PoE injectors. Now, let us have a look at some of the best PoE switches and PoE injectors available out there in the market. We have covered all the essential specs and details, which will help you to choose the right product according to your requirement:
It is an integrated power over Ethernet Plus a.k.a (PoE+) switch with options for Layer-3 routing (static). The configuration software is secure and supports IP Telephony as well. Overall, it is a midrange, budget switch with additional features which you might or might not use. If you are familiar with the Linksys UI, then your setup experience would be a breeze.
If you have additional IP based security cameras or Access points, this switch is a good option.
Just like the Linksys router, the NetGear router also comes with managed POE+ capabilities. It has advanced smart networking features, such as access control, DiffServ & LACP. It also supports Link aggregation which is useful for higher logical bandwidth.
The L3 routing capability is excellent for VOIP and other network communications. The web interface can be quickly learned and easily accessible.
We recommend this device for non-technical users who are looking for a plug and play device.

The DGS-1100 is an absolute winner in the eight-port affordable POE+ switch category. It comes equipped with L2 switching features such as VLAN & QoS, along with easy to use intuitive management interface. The switch immediately recognizes FE vs. gigabit-ethernet appliances plugged into it, and depending on the interface speed of the device, either the amber or the green LEDs on the switch ports light up respectively, giving you immediate visual verification of what the speed is.
DLink provides a lifetime warranty on the device and is also a fanless solution. Since the device is passively cooled, there will not be any noise from the device whatsoever. Whats more, the company also provides a lifetime warranty on the switch which is always helpful.
In case if you do decide to purchase it, ensure to flash the switch with the latest firmware. Check out its specifications below:
