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)
8-port 10/100/1000M PoE Ethernet Switch with 4-port PoE and 1-port PD
Highlights:
The device is a powerful, high-performance Gigabit Ethernet Switch, with all 8 ports capable of 10/100/1000Mbps auto-negotiation operation (NWay), which means the switch could automatically negotiate with the connected partners on the network speed and duplex mode. It is ideal for micro-segmenting large networks into smaller, connected subnets for improved performance, enabling the bandwidth demanding multimedia and
imaging applications. Moreover, the 10/100/1000Mbps auto-sensing ability provides an easy way to migrate 10/100Mbps to 1000Mbps network with no pain.
This switch supports PoE pass-through, having both PD (Powered Device) and PSE (Power Sourcing Equipment) features in one single device, which means the switch could get power from the PD port by connecting to a PSE device and supply power on the 4 PSE ports for connected devices via CAT 5e or better twisted cables. By integrating the data transmitting cable and power cord, it eliminates the effort constructing your network. You could easily connect a Wireless AP or a VoIP phone (PD devices) to this switch without looking outlets for them. Over current protection and circuit shorting protection are also supported to ensure the safety.
The switch is plug-n-play without any software to configure and also fully compliant with all kinds of network protocols. Moreover, the rich diagnostic LED indicators on the front-panel provide the operating status of individual port and whole system.
