MikroTik RB411GL with 680MHz Atheros CPU, 32MB RAM, 1x Gbit LAN, 1 miniPCI, RouterOS L4
The board has a direct-input power jack J801 (5.5mm outside and 2mm inside diameter, female, pinpositive plug) and can as well be powered with PoE. All power inputs are always active, but only one should be used at the same time.
RouterBOARD 411 is equipped with a reliable 14W onboard power supply with overvoltage protection. 9..28 V DC input voltages are accepted, but when powered over long cables, it is suggested to use at least 18V. The system is tested with 24V solar/wind/RV systems with 27.6 charge voltage. Overvoltage protection starts from about 28V (up to 100V), so the board will not be damaged if connected to a 48V or 60V power line.
RouterBOARD 411 series boards are compatible with non-standard (passive) Power over Ethernet injectors (except power over datalines) and accept powering over up to 100m (330 ft) long Ethernet cable connected to the Ethernet port (J602). The board does not work with IEEE802.3af compliant 48V power injectors.
