PoE (or Power over Ethernet) technology allows you to deliver both power and data over a single cable. This helps you to save on equipment and cabling costs. It also provides you with more installation flexibility since you won’t be restricted to setting up end devices next to power outlets. There are many devices that utilize PoE technology including powered devices (PD), such as IP cameras or access points, and power sourcing equipment (PSE), such as NVRs with built-in PoE switches, Powerline adapters, or standalone PoE injectors.
There are different types of PoE: PoE, PoE+, and the relatively new UPoE and higher-power PoE standards. Each PoE standard allows for an increasing amount of maximum power that can be delivered to each device (or per each port of a connected PoE switch).
| Standard | Type | Max. Power per Port |
| 802.3af | PoE | 15.4W |
| 802.3at | PoE+ | 30W |
| 802.3bt | PoE++* / UPoE* | 60W |
| 802.3bt | 4PPoE* | 95W |
When planning your projects, remember to confirm total PoE budget. If you have two PoE ports, but only a 20-watt PoE budget, both ports will not be able to supply the full 15.4 watts of power to those ports simultaneously. Luckily, most PoE end devices do not require the full PoE budget the standard allows.
PoE devices do not usually use the maximum amount of power that their respective PoE standards allow. For example, a port on a PoE switch supplies up to 15.4 watts of power, but your PoE camera may only need 9 watts of power. However, each PoE device is assigned a PoE class, and this may affect your total available PoE budget.
| Class | Standard | Type | Max. Power Available |
| 0 | 802.3af | PoE | 15.4W |
| 1 | 802.3af | PoE | 4.0W |
| 2 | 802.3af | PoE | 7.0W |
| 3 | 802.3af | PoE | 15.4W |
| 4 | 802.3at | PoE+ | 30W |
| 5 | 802.3bt | PoE++* / UPoE* | 45W |
| 6 | 802.3bt | PoE++* / UPoE* | 60W |
| 7 | 802.3bt | 4PPoE* | 75W |
| 8 | 802.3bt | 4PPoE* | 95W |
Your device’s PoE class will let your PoE switch know the maximum amount of power that PoE device may require. However, if your PoE device needs less than the maximum wattage to operate, the PoE switch may still reserve the amount of maximum wattage based on the PoE class.
For example, TRENDnet’s 8MP 4K H.265 PoE IR Bullet Network Camera (TV-IP318PI) is a PoE camera with a maximum power consumption of 7.5 watts. However, since the PoE camera is designated as a class 3 PoE device, the connected PoE switch may reserve the full 15.4 watts power maximum. This would reduce your PoE switch’s total available PoE power budget by 15.4 watts, instead of just 7.5 watts.
If you’re unsure what class your PoE end device is, a good rule of thumb is to round up (based on the maximum wattage available per class). Note that not all PoE switches will reserve power based on the PoE class; some PoE switches may determine available power based on current PoE load.
Dueltek will be conducting it's annual stocktake soon. During this period we will not be able to despatch products, but our sales team will still be available to receive orders and offer technical support.
Please be advised that the Dueltek warehouse will be closed from Monday 15 July 2019 and re-opening 8am Thursday 18 July 2019.
Thank you for you continued support and understanding.

Mechanical & Electrical Properties:
A network switch’s basic function is to connect devices together on your computer network. Network switches are available with varying amounts of ports and features to meet the needs and demands of your working project.
Switches are already “smart” devices; after receiving data, the switch sends that data to a specific device on the network (and not a blanket transmission to all connected devices). This is particularly useful as the switch is able to receive data from all connected devices and transmit that data to specific devices simultaneously.
There are two types of switches: unmanaged and managed. Amongst those, managed switches are further broken down by varying sub-categories. Simply put, managed switches feature network controls that allow you to customize, manage, and monitor your network. Conversely, unmanaged switches are “plug and play” solutions, designed only to increase port density and cannot be further configured.
TRENDnet offers both unmanaged and managed switches (Layer 2/Layer2+ and Web Smart). Today, not much differs between Layer 2 and Web Smart switches; both Layer 2 switches and Web Smart switches feature a graphical user interface (GUI), however, only Layer 2 switches offer a command line interface (CLI).
The CLI and GUI each have their own advantages and disadvantages. However, a command line interface is generally viewed as more efficient, allows for more control over the system, and is easier to use for remote access. However, it is designed for more advanced network administrators.
Simple Network Management Protocol is for monitoring the status and management of devices connected to the network.
Virtual LAN configurations group devices together to isolate traffic, improve network performance, add an extra layer of security, and reduce unnecessary network traffic.
Quality of Service allows you to prioritize your network traffic and improve performance (commonly used in VoIP and video applications).
Rapid Spanning Tree Protocol and Spanning Tree Protocol are used for redundancy in the network and to prevent looping. RTSP recovers the network from a failed link and locates a new network path in significantly less time than STP.
Port mirroring helps to identify and troubleshoot network problems by mirroring data traffic to a designated port on the switch.
IGMP snooping eliminates network congestion caused by multicast traffic. IGMP snooping ensures that multicast data is only forwarded to specific devices that exclusively request the multicast data rather than sending that data to all the devices connected to the network (commonly used in IPTV applications).
Class
There are several types of switches, each providing different levels of management. Unmanaged switches allow you to expand your network easily with no special configuration or specialized networking knowledge. Unmanaged switches simply increase the number of ports (or available connections) to your network by increasing port density.
Web smart and layer 2 managed switches have additional features such as VLAN support, PoE controls, traffic analysis, and multicast support. EdgeSmart switches are basic web smart switches that offer only the most commonly used management features to help reduce both cost and setup complexity.
There are many different levels of managed switches (and not all are discussed here, such as Layer 3 switches); the type of switch you need and the best switch for your network will depend on the features required for your project. (See TRENDnet Managed Switches 101 Whitepaper for more info on managed switches).
Speed
Required bandwidth will determine whether you need a 10G, 2.5G, Gigabit, or 10/100 switch. Fast Ethernet or 10/100 switches are more cost-effective, but Multi-Gigabit and Gigabit switches can provide better scalability. Choose a speed that is enough for your current project, but plan for the future and consider extra bandwidth.
Specialized Switches
Look for specialized switches, such as industrial switches or AV switches, to meet the unique needs of your custom networking project(s).
Determine how many devices that need to be connected in order to identify the number of ports you’ll need. For your surveillance solutions, we recommend reserving 2 additional ports for your NVR and/or network bridge/client.
The form factor that you choose will come down to both your own personal preference and the switch’s application. Desktop and wall-mountable switches are great when you want to save space; they are generally more affordable and are quieter since most desktop and wall-mount switches do not have internal fans. Rackmount switches are ideal when you want to integrate it into a new or existing server room or rack. DIN-rail switches are usually reserved for industrial applications.
Plastic or metal?
Having trouble deciding which type of housing is best for you? Metal switches are more durable, but plastic switches are a cost-effective solution.
Knowing the class of the switch chosen in step one helps us identify the possible feature set of that switch. However, regardless of class, switches can have varying features, and the features you want will depend on your project’s needs. Review the switch features to make sure you choose the best switch for your network.
Unmanaged switches have no management features. Managed switches include a variety of features for traffic management, troubleshooting, access controls, and monitoring. Some common features include LACP, VLAN, QoS, IGMP snooping, and bandwidth control per port. Once you’ve chosen your switch, double-check that it offers the features you need, as switches can have differing feature sets even within the same class.
