PoE Powered Switche (PD)
PD: A switch that is itself supplied with PoE
Switches that have PoE outputs are nothing new - but it becomes interesting when switches themselves are supplied with PoE, i.e. they have a PoE input. Why is this important? Imagine you are using a manageable PoE switch with many ports in a storey cabling system, which now connects the switches to the to the workstations. If you now use a PoE Powered Switch at the workstations, you can save all power supplies. In addition, you can switch the ports of the PD switches on or off using the manageable switch, for example time-controlled. Of course, this also offers a security aspect: no power supply - no access to data on IP phones, computers, etc. Or let's look at another case: You want to install an access point or IP camera at a location in the building where there simply is no power outlet nearby. Here, a PD switch is used which can be controlled by a manageable switch, as in the previous example. Even more extreme is the case in a large warehouse: let's say the nearest power connection is 700 meters away, but you still have to install an IP camera in the back corner. No problem with the LT PoE Switch (with 90W!)
and a LT PoE repeater that can refresh the PoE signal every 100 meters - 6 times in a row!
Smart-Managed PoE Powered Switche (PD)
Unmanaged PoE Powered Switche (PD)
Unmanaged PoE Powered Switches (PD) for indoor switch cabinets/power distribution boards "Hager etc"
ALLNET Switch unmanaged 5 Port - 5x GbE - PoE Budget 85W - 4x PoE af/at out 1xPoE bt 90W in - Fanless, DIN, PD-Input - ALL-SG8005PD-BT90
Highlights:
The ALLNET ALL-SG8005PD Gigabit PoE+ Extender/Switch is a compact, high-performance device harnessing the latest network standards to extend your Ethernet signal up to 100 meters per device. With the capability to reach a total range of up to 500 meters, this extender offers flexibility and versatility.
Operating via Power over Ethernet (PoE), this amplifier eliminates the need for a separate power supply. This feature allows its deployment in locations without existing power cables or outlets, expanding range or connectivity effortlessly. The 4 PoE ports provide a maximum budget of 85W PoE power. Port 2 delivers up to 60W, while ports 3-5 can supply a maximum of 30W per port. Furthermore, ports 2-5 support both PoE and non-PoE compatible devices, ensuring flexible utilization.
This solution is ideal for ensuring a reliable network connection in cabinets or electrical enclosures. The additional ports can accommodate IoT devices or other smart home endpoints, further enhancing the versatility and applications of this extender.
The switch offers the option to toggle between two operating modes via a switch: OFF-Normal mode or ON-VLAN & 250M PoE. In VLAN & 250m PoE mode, devices cannot communicate with each other, also known as Port Isolation. Moreover, the network range for 100Mbps devices extends to a maximum of 250m, while Gigabit devices maintain a range of 100m."
