Internet Protocol over Ethernet (IPoE) is a method of delivering an IP payload over an Ethernet-based access network or an access network using bridged Ethernet over Asynchronous Transfer Mode (ATM) without using PPPoE. It directly encapsulates the IP datagrams in Ethernet frames, using the standard RFC 894 encapsulation. In IP over Ethernet (IPoE) scenario, a PC is connected to the Ethernet interface of a BRAS through a Layer 2 device (such as LAN Switch). When the PC accesses the IPv4 network, a user IP packet is encapsulated into an IPoE packet on the Ethernet interface. The IPoE packet is forwarded to the BRAS through the Layer 2 device. The BRAS then authenticates the user and authorizes user services based on physical or logical information carried in the IPoE packet, such as the MAC address, VLAN ID, and Option 82 (line information).

As you can see above, if DHCP Relay Agent is used, then DHCP messaging will be changed. Here, Resident Gateway sends a DHCP Discover Message as broadcast. This broadcast Discover Message is received by Relay Agent BSR and it is sent to DHCP Server directly. DHCP Server replies with DHCP Offer including an IP offer to BSR and BSR sent this offer as broadcast. Resident Gateway sends DHCP Request to BSR this time. This shows the acceptance of the IP. This time and BSR will send it to DHCP Server. Lastly, DHCP Server sends DHCP Offer to Relay Agent BSR and it send it as broadcast again. Resident Gateway receives this IP and uses. (Source:

Having the capability of IEEE 802.3at Power over Ethernet standard, the IPOE-162 can directly connect and inject power via RJ45 Ethernet cable to any IEEE 802.3at end-nodes like PTZ (Pan, Tilt & Zoom) network cameras, PTZ speed dome cameras, color touch-screen voice over IP (VoIP) telephones, multi-channel wireless LAN access points and other network devices. (Source:Planet IPOE-162S is an Industrial High Power PoE Splitter that can split the 48~56V DC over the existing Ethernet cable into the selectable 12V or 24V DC power output. It supports passive 10/100/1000Mbps Ethernet connection ability and complies with IEEE 802.3at High Power over Ethernet standard that supports up to 25-watt output power to powered device. To fulfill the growing industrial applications, the IPOE-162S is designed to work under the operating temperature range from -40 to 75 degrees C (-40 to 167 degrees F). The IPOE-162S is an ideal solution to transferring power to traditional network device with high power demand directly without the need to install additional power outlets and electrical cabling in the industrial environment.
