9 FM-POE – Quad LAN with Power over Ethernet PSE ports
9.1 Description
FM-POE FACE Module incorporates 4 ports of GbE LAN supporting 10/100/1000BASE-T Ethernet
connectivity, compliant with IEEE 802.3/u/ab standard. All four ports compliant with IEEE 802.3af*
support PoE and PoE + PSE applications. Two additional USB2.0 downstream ports supporting data rates
up to 480Mbps for general purpose connectivity.
Note that HW Rev1.0 supports PSE Class 0 (15.4W max) per port when 2 ports populated with PD Class 0
devices (12.95W max).
10 Refer to Compatibility Matrix for products fit.
