LEDs
Power LED
Power LED is on when the board is powered.
User LED
User LED may be programmed at user's option. It is lit by default when the board starts up, then it is turned

User's Guide
Assembling the Hardware
First to use the board:
●
Install the board in a case;
●
Connect antenna to the MMCX/uFL connector (depending on model)
●
Connect the PoE powered Ethernet cable or plug the Power jack. Note! Antenna should be connected
before powering on the device
Powering
●
Power over Ethernet (PoE) on the Ethernet port:
10..28V DC (12..28 V suggested) non-standard PoE powering support
●
Power jack 10..28V (12..28V suggested), RB711A model only.
RouterBOARD 711 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 (
J4
). The board
does not
work with IEEE802.3af compliant 48V power injectors.
