What is Power over Ethernet?

POE (Power Over Ethernet)

By Rich Tull

What is PoE Power-over-Ethernet is a term for a technology that allows data and power to be transmitted over a 100meter distance using the same Ethernet cable. For powering the system, this technology eliminates the need for a separate power line and an electrical link (AC). The technology also helps to remove the need for cables and other connection-related accessories.

What is PSE? PSE – Power Sourcing Equipment The PSE is the device that supplies power to the PDs. The key roles of the PSE are: To look for a PD in the connection section.

Classify the PD if desired.

Connect the connection section to a power source. (only if a PD is detected) On the connection section, keep an eye on the control.

End span and midspan are the two types of power source equipment identified by 802.3af.

An Ethernet switch with embedded Power over Ethernet technology is referred to as endspan.

In most cases, midspan devices are mounted between legacy switches and powered devices.

How do I know if a PoE Network Switch will work for my application?

Programming makes the difference If the switch programming is limited to all ports ON or all ports OFF then power is shared among all ports and full power output is not possible for all ports simultaneously.

If a switch’s programming allows different power levels to be allocated to individual ports then the number of ports that can provide full power will be limited to the total available switch power.

VERSITRON PoE SWITCHES The data flow in the network is regulated by these PoE switches. Since a continuous PoE network link is not needed, the switches allow data to be transmitted via cable only when it is required.

10-PORT POE FIBER SWITCH

18-PORT POE FIBER SWITCH

28-PORT POE+ SWITCH

52 PORT POE SWITCH
