RB2011UiAS-RM – The RouterBOARD 2011UiAS-RM has five Gigabit LAN ports and five Fast Ethernet LAN ports, but also has RJ45 serial port, USB port and more RAM (128MB). New batches of RB2011 series, that are shipping now, have an i letter in the product SKU. This stands for injector, meaning that LAN port #10 now has PoE output function. It can power other PoE capable devices with the same voltage as applied to the unit. Less power adapters and cables to worry about. Maximum load on the port is 500mA at 24V for 12W of output support for RBSXT series and other CPE devices. Router BOARD RB2011UiAS-RM, in comparison with RB2011L series, not only has five Gigabit LAN ports and five Fast Ethernet LAN ports, but also has RJ45 serial port, USB port and more RAM (128MB instead of 64MB).
