'''Intel I211AT GbE Controller'''
Intel Ethernet I211 controller is a single port, compact, low power component that supports GbE designs. The I211 offers a fully-integrated GbE Media Access Control (MAC), Physical Layer (PHY) port and supports PCI Express 2.1 (5GT/s). The I211 enables 1000BASE-T implementations using an integrated PHY. It can be used for server system configurations such as rack mounted or pedestal servers, in an add-on NIC or LAN on Motherboard (LOM) design. Another possible system configuration is for blade servers as a LOM or mezzanine card. It can also be used in embedded applications such as switch add-on cards and network appliances.

'''Linear Technology LTC4266C Quad PoE + PSE Conrtoller'''
When connected directly to the host system or configured in Auto mode, each Si3452 high-voltage port controller provides all of the critical circuitry and sophisticated power measurement functionality for the high-voltage interfaces of four complete PSE ports. The Si3452 fully integrates robust, low-RON (0.3Ω typical) power MOSFET switches, low-power dissipation current sensing circuitry, and transient voltage surge suppression devices. The on-chip current sense circuitry and power MOSFETs provide programmable scaling of current limits to match PoE (350 mA, 15.4 W for 2 ports) and PoE+ (600 mA, 30 W for one port) power requirements on a per port basis. Each Si3452 also performs the IEEE-required powered device (PD) detection, classification, and disconnect functionality.<br>
+
The LTC4266С is a quad power sourcing equipment (PSE) controller capable of delivering PoE power to a compatible PoE powered device (PD).
The flexible architecture enables powered device disconnect detection using Silicon Laboratories proprietary dV/dt disconnect sensing algorithm. dV/dt disconnect is an alternative to DC disconnect that requires no additional BOM components, does not dissipate extra device power, and fully interoperates with all powered devices. Also provided are multi-point detection algorithms and per-port current and voltage monitoring.<br>
+
A proprietary detection/classification scheme allows mutual identification between a PoE PSE and PoE PD while remaining compatible and interoperable with existing Type 1 (13W) PDs.
Intelligent protection circuitry includes power supply under voltage lockout (UVLO), port output current limiting and short-circuit protection, thermal overload sensing and port shutdown, and transient voltage surge suppressors capable of protecting the Si3452 from a variety of harsh surge events seen on the RJ-45 interface.  
+
These PSE controllers feature low RON external MOSFETs and 0.25Ω sense resistors which are especially important at the PoE current levels to maintain the lowest possible heat dissipation.
To maximize system design flexibility and minimize cost, each Si3452 connects directly to a system host controller through an I2C serial interface.

Safety Information

  • On every use of FM-POE to deliver Power over Ethernet:
    • In conjunction with fit-PC and Intense PC computers, 12V power supply must be applied to power jack on the front panel of FM-POE. The use of PoE with the power supplied via the system board back panel may result in permanent damage to the system.
    • In Airtop systems, power should be applied to the Airtop power input instead of FACE Module power input. FACE Module power input must not be powered!
