Sep 25, 2020 With Ethernet and Lightning ports, you can connect to a secure network while continuing to charge your device. Power over Ethernet (PoE) compatibility provides another convenient way to connect and charge simultaneously with a single cable. Combining Ethernet and reliable power makes this adapter perfect for businesses using cloud-based POS. Using point-to-point copper cabling provides the opportunity to transmit low electrical power along with the data. This is called Power over Ethernet and there are several, incremental IEEE 802.3 standards. Combining 10BASE-T (or 100BASE-TX) with 'Mode A' allows a hub or a switch to transmit both power and data over only two pairs.

IEEE 802.3 is a working group and a collection of Institute of Electrical and Electronics Engineers (IEEE) standards produced by the working group defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. This is generally a local area network (LAN) technology with some wide area network (WAN) applications. Physical connections are made between nodes and/or infrastructure devices (hubs, switches, routers) by various types of copper or fiber cable.
- Connect your Mac to the internet using Ethernet. You can use Ethernet to connect to the internet, either through an Ethernet network or through a DSL or cable modem. If you’re using a modem, make sure the modem is turned on and connected to the wall jack with the cable that came with the modem.
- The Ethernet over Power adapters offer users a wide range of networking solutions over the powerline. It uses the existing power line as data transmission media terminal. The new high-speed generation of home plug adapters allows you the tranfering of data, video streaming, heavy-duty files such as photo and videos all transmitted over the.
802.3 is a technology that supports the IEEE 802.1 network architecture.
802.3 also defines LAN access method using CSMA/CD.

Q: I’ve connected the Gigabit + PoE Adapter to the iPad but I do not see “Ethernet” in the Settings app on my iPad. What do I do?
A: The first step in troubleshooting is to look at the power LED on the L6-NETPOE to see if the L6-NETPOE is receiving power from the PoE switch. (Power LED is located between the ethernet jack and the micro USB port.)

Ethernet Over Power For Mac Catalina
If the power LED is ON there are 3 possible causes of the problem:
• The Redpark Lightning cable that you are using is bad.
• You chose to use a cable that is not a Redpark Lightning cable — and your cable does not work with the L6-NETPOE.
• The PoE switch is not providing a full 15.4W to the L6-NETPOE. (The switch may be loaded with too many PoE devices and is unable to provide full power to the L6-NETPOE.)
• The Redpark Lightning cable that you are using is bad.
• You chose to use a cable that is not a Redpark Lightning cable — and your cable does not work with the L6-NETPOE.
• The PoE switch is not providing a full 15.4W to the L6-NETPOE. (The switch may be loaded with too many PoE devices and is unable to provide full power to the L6-NETPOE.)
Power Over Ethernet Line
If the power LED is OFF there are 5 possible causes of the problem:
• Your ethernet switch does not provide PoE. (If you are not sure, email the brand and model of the switch to us.)
• You are plugged into a port on the switch that is not a PoE port. (Most PoE-enabled switches have PoE ports and non-PoE ports.)
• There is a problem on your network between the L6-NETPOE and the switch. (Try plugging the L6-NETPOE directly into the switch using a short ethernet cable.)
• The PoE port on the switch may be configured to power a lower power device (i.e. a VoIP phone) and provides no power to the L6-NETPOE (because the L6-NETPOE requires too much power).
• The switch provides a non-standard version of PoE. Ubiquiti, for example, sells switches that provide 24V PoE. These switches work with certain Ubiquiti devices but are not able to power the L6-NETPOE.
• Cisco sells several series of switches that use UPOE — a Cisco extension of the PoE standard. Some early customers reported problems using the L6-NETPOE with a Cisco UPOE switch. In studying this issue with Cisco’s help we learned that UPOE switches use a proprietary method to detect powered devices. We revised the L6-NETPOE to ensure reliable detection by UPOE switches. The revised units have the code “0418” appearing on the label on the underside of the L6-NETPOE. These units have been in production since May 2018.
• Your ethernet switch does not provide PoE. (If you are not sure, email the brand and model of the switch to us.)
• You are plugged into a port on the switch that is not a PoE port. (Most PoE-enabled switches have PoE ports and non-PoE ports.)
• There is a problem on your network between the L6-NETPOE and the switch. (Try plugging the L6-NETPOE directly into the switch using a short ethernet cable.)
• The PoE port on the switch may be configured to power a lower power device (i.e. a VoIP phone) and provides no power to the L6-NETPOE (because the L6-NETPOE requires too much power).
• The switch provides a non-standard version of PoE. Ubiquiti, for example, sells switches that provide 24V PoE. These switches work with certain Ubiquiti devices but are not able to power the L6-NETPOE.
• Cisco sells several series of switches that use UPOE — a Cisco extension of the PoE standard. Some early customers reported problems using the L6-NETPOE with a Cisco UPOE switch. In studying this issue with Cisco’s help we learned that UPOE switches use a proprietary method to detect powered devices. We revised the L6-NETPOE to ensure reliable detection by UPOE switches. The revised units have the code “0418” appearing on the label on the underside of the L6-NETPOE. These units have been in production since May 2018.
