Booting process
RouterOS is the operating system of all RouterBOARD routers. Please see documentation: http://mt.lv/help
This device is not preconfigured other than an IP address on the Ethernet port. Other configurations has to be
applied according to the documentation manual linked above.
In case you wish to boot the device from the network, for example to use MikroTik Netinstall, hold the reset button
of the device when starting it until the LED light turns off, and the device will start to look for Netinstall servers.
In case IP connection is not available, the Winbox utility can also be used to connect to the MAC address of the
device. More information in the documentation.
Extension slots and ports
•
Three gigabit Ethernet ports (With Auto MDI/X so you can use either straight or cross-over cables for
connecting to other network devices). The J1 (first from the left) Ethernet port accepts 11-30 V DC
powering from a passive PoE injector.
•
Two miniPCIe slots for either a 802.11 wireless card or a 3G/LTE modem. Mini SIM 2FF slots available for
miniPCIe 3G/LTE modems and have no functionality when a modem is not installed.
•
One M.2 (M key) slot for PCI-e SSD disk or other devices. The mounting hole is for 2242 size cards, for
other sizes, an extender is suggested. Any speed M.2 cards will operate at 1x PCIe speed.
•
One microSD slot for a storage card.
•
One DB9 RS232 serial port for serial console access. Configured as 115200 bit/s, 8 data bits, 1 stop bit, no
parity.
USB jumper
Located right next to the USB 3.0 port. When loaded, the jumper enables the USB 3.0 port. Remove the jumper to
switch the USB 2.0 lines to the J10 (central) miniPCIe slot (USB 3.0 lines remain enabled to the USB port). This is
required if you need to use two cellular modems in the device. Normally you can use the LTE modem in the J8 (left-
hand side) slot, and use a 802.11 wireless card in the J10 slot. In this case, you can leave the jumper on, as most
wireless cards operate on a PCI express. Removing the jumper enables the use of a secondary cellular modem in
the central J10 slot, but disables the USB 2.0 functionality of the USB port, while USB 3.0 can still be used on the
USB port. Refer to the diagram below:
